In this work magnetic particles are synthesized by in situ formation of magnetite in the gel phase through coprecipitation of Fe(II) and Fe(III) in alkaline media. Preparation parameters of Fe<sub>3</sub>O<sub>4</sub> nanoparticles are full tested by orthogonal test. The study is devoted to synthesis and characterization of the structure and properties of Fe<sub>3</sub>O<sub>4</sub> nanoparticles and magnetic field sensitive polymer gels composed of cross-linked PVA and magnetite. The structure and properties of magnetic field sensitive polymer gels and Fe<sub>3</sub>O<sub>4</sub> nanoparticles are studied by X-ray diffraction (XRD), transmission electronmicroscopy (TEM), vibration sample magnetometery (VSM), electron microscope (EM) and infrared (IR).The ability of this magneto-elastic magnetic field sensitive polymer gels to deflect in the presence of a magnetic field was explored in this study. The dependence of deflection on the iron oxide concentration and magnetic field strength was also investigated. Finally, one approach on how to make a soft finger of robot were discussed.
Ionic polymeric gels are three-dimensional networks of cross-linked macromolecular polyelectrolytes that swell or shrink in aqueous solutions in addition of alkali or acids, respectively. Linear reversible dilation and contraction of the order of more than 1000 per cent are observed in a laboratory for polyacrylonitrile fibers. It is experimentally observed that swelling and shrinking of ionic gels can also be induced electrically. Thus, direct computer control of large expansions and contractions of ionic polymeric gels by means of a voltage gradient appears to be possible. A mechanism is presented for the reversible nonhomogeneous large deformations and in particular for bending of strips of ionic polymeric gels in the presence of an electric field. Exact expressions are given relating the deformation characteristics of the gel to the electric field strength or voltage gradient, gel dimensions and other physical parameters such as the resistance and the capacitance of the gel strip. It is concluded that direct voltage control of such nonhomogeneous large deformations in ionic polymeric gels is possible.<<ETX>>
Vanadium dioxide (VO2) is a dark blue inorganic compound and excellent material with a high potential for smart window application due to its characteristic. A research to study the effect of different rotation per minutes (rpm) of spin coater on VO2 thin films was conducted. A suitable precursor was formed by mixed a vanadium oxytripropoxide with isopropanol into the clean beaker and mixed slowly. Part of the process, spin coater and heat treatment were used to form a thin layer of VO2 on ten pieces of quartz substrates by applied a standard operation set up. The samples then were characterized by Field Emission Scanning Electron Spectroscopy (FESEM) for thickness measurement via cross section process and surface morphology of the grains. The range of measured thickness and size of grain were 520nm to 1960nm and 300nm to 349nm respectively. The results shown that, the quality of the fabricated VO2 in terms of thickness and surface morphology were inversely proportional with rpm of the spin coater.
This paper describes a novel method to fabricate micrometer sized gel patterns. The method involves spin-coating a pre-gel solution on a surface that was chemically treated to modulate its surface energy, creating highly hydrophobic areas on a hydrophilic substrate. Following spin coating, the gel solution self organizes on the hydrophilic sites. This method offers the advantages of high resolution, self-alignment to pre-patterned electrodes, and a simple straightforward fabrication process. The gel features are incorporated into microfluidic channels. The overall purpose of this approach is to create a simple, affordable, microfluidic device, which incorporates "smart" hydrogel elements.
The effect of the pre-heating temperature on the deposition of c-axis oriented thin ZnO films has been investigated, after fixing a low annealing temperature. The deposition process is optimized to be compatible with silicon /silicon-dioxide substrates, to make piezoelectric coatings for integrated smart sensors. Deposition is carried out on glass and oxidized silicon substrates. The dependence of the c-axis orientation on the pre-heating temperature has been studied by applying experimental design and response surface techniques. The films are synthesized by the sol-gel method. The effect of the deposition conditions on the characteristic (002) peak is determined by X-ray diffraction analysis. Surface uniformity and grain size is observed by SEM. It is observed that the pre-heating temperature has a strong effect on the orientation of the film.
Fe3O4 nanoparticles can be prepared by chemical co-precipitation. By using them in artificial muscle, it can be droved by magnetic field. Characterization was also performed by X-ray Diffraction (XRD), Transmission Electron Microscope (TEM) and Vibration Showpiece Magnetor (VSM). Fe3O4 is dispersed in polyvinyl alcohol (PVA) hydrogel to make new type intelligent hydrogel - magnetic field sensitive polymer gels. Observe gel's surface through EM (Electron Microscope). IR (Infrared) of PVA and Fe3O4 nanoparticles magnetic sensitive polymer gels is detected. The different proportion Fe3O4 and Fe3O4 magnetic field sensitive gels were tested in magnetic field for observing their deflection. Utilize the characterization of different deflection to make a finger of robot by changing the proportion of Fe3O4.
Four ionic liquids (ILs), trihexyl (tetradecyl) phosphonium methanesulfonate ([mes<sup>-</sup>]), trihexyl (tetradecyl) phosphonium dodecylbenzenesulfonate ([dbs<sup>-</sup>]), trihexyl (tetradecyl) phosphonium chloride([Cl<sup>-</sup>]) and tetrabutyl phosphonium methanesulfonate ([tbt<sup>+</sup>]), were chosen to add to plasticized poly(vinyl chloride) (PVC) gels for improving actuation behavior at low electric fields. It was found that the IL trihexyl (tetradecyl) phosphonium chloride ([Cl<sup>-</sup>]) is best matched to PVC gels, and the amount of IL is an important factor for PVC gel actuation. With less than 0.01 wt% of IL the PVC gel can actuate similarly to the gel without IL, but less than half of the DC voltage is required. It was also found that PVC gel with a minute quantity of IL not only maintained the deformation properties of the PVC gel without IL, but also enhanced the dielectric constant and decreased the interfacial resistance. However, increasing the amount of IL from 0.01 to 0.02 wt% resulted in one way bending and delayed recovery response, while more than 0.02 wt% resulted in almost no actuation response. The reason for these observations was confirmed as being accumulation of electric charges in the PVC gel interior with increased IL content. The accumulated ionic liquid resists migration of electric charges and causes smaller deformation or recovery response.
In the present article we report copper (Cu) doped ZnO (p-type) thin-film based heterojunction diodes grown on p/n-Si substrate. Sol-gel spin coating method has been used to deposit the Cu doped ZnO thin films on p/n-type silicon. The p-type nature of the deposited Cu doped ZnO thin films have been confirmed by hot point probe method. The electrical parameters of the as fabricated devices have been gauged from I-V characteristics. The ZnO based devices on Si platform are expected to be deployed in future generation smart systems for UV/gas sensing and photovoltaic applications.
The thin films of lead titanate (PbTiO<sub>3</sub>) have been prepared on ITO coated glass substrate by means of storage element for DC power application. The solution was prepared by modified sol-gel process that involved sonication process to ensure the uniform nanoparticulates formation before ageing stage take parts. In the need to compensate the lead loss, extra 10mol% of Pb content was added to the solution. The thin films were deposited at high spin speed around 3500 rpm at 30 seconds with multiple coating processes. Microstructural observation was done through scanning electron microscopy that shows the existence of zero layers between PbTiO<sub>3</sub> and ITO electrode and the film thickness was about ~420nm. Besides that, electrical properties of PbTiO<sub>3</sub> thin films were measured by using impedance spectroscope analyzer and 2-points probe solar simulator for dielectric and i-v characteristic respectively. It was found that the dielectric constant value achieved 153 at 1000 Hz plus with approachable of 0.723 energy loss. It is certainly noticed that the thin films was in ohmic behavior where the current density was about 10<sup>-9</sup>A/cm<sup>2</sup>.
Stimuli-responsive polymer gels and their application to smart materials have been widely studied. On the other hand, as a novel biomimetic gel, we developed gels with an autonomous self-oscillating function like a heart muscle, which was firstly reported in 1996. We designed the self-oscillating polymers and gels by utilizing the oscillating reaction, called the Belousov- Zhabotinsky (BZ) reaction as a chemical model of the TCA cycle. The self- oscillating polymer is composed of a poly(N-isopropylacrylamide) network in which the metal catalyst for the BZ reaction is covalently bonded. In a closed solution containing the reactants other than the catalyst, the polymer gel undergoes spontaneous cyclic swelling-deswelling changes without any on-off switching of external stimuli. Their potential applications include several kinds of functional material systems, such as biomimetic actuators and mass transport surface. Here recent progress on the novel polymer gels is introduced.
