  • Simulation of carbon nanotubes polymer based piezoresistive flexible pressure sensor for ultra sensitive electronic skin

    The design and sensitivity of a piezoresistive pressure sensor based on single-walled carbon nanotubes-polymer nanocomposite and multi-walled carbon nanotubes-polymer nanocomposite has been investigated. The paper dwells on the nuances of modeling flexible piezoresistive pressure sensor using COMSOL Multiphysics Finite Element Modeling (FEM) software. The response of each of the above sensor has been simulated for pressure loading (0-130 Pa). The simulation results show an increase in the resistance of piezoresistive material with an increase in the application of pressure. The obtained piezoresistive response of both carbon nanotubes based sensors is compared.

  • The Effect of Ultrasonic Dispersion on the Surface Chemistry of Carbon Nanotubes in the Jeffamine D-230 Polyetheramine Medium

    This paper studies changes in the surface chemistry of carbon nanotubes (CNTs) where they are under ultrasonication process in Jeffamine D-230 polyetheramine medium. Jeffamine is used as a curing agent in the nanocomposite manufacturing process. In the nanocomposite technology, ultrasonication process is employed as a method for dispersion of CNTs in a suspension. This research tries to investigate the effect of ultrasonic dispersion with different time and energy on the surface chemistry of CNTs by Fourier transform infrared spectroscopy. The results show ultrasonication of CNTs in the Jeffamine medium leads to significant oxidation and hydration along creating new chemical bonds on the CNTs surface.

  • A generalized model for the signal propagation along single- and multi-walled carbon nanotubes with arbitrary chirality

    The paper presents a self-consistent semi-classical model describing the electrical behavior of carbon nanotube interconnects. The model deals with the general case of arbitrary chirality and takes rigorously into account the effects of nanotube size and chirality on its electrical parameters. The general model includes as particular cases the models currently used in literature to describe metallic carbon nanotubes with small radius. The analysis of bundles of single-walled and multi-walled carbon nanotubes is carried-out. The model is also used to derive a semi-analytical approximation for the number of equivalent conduction channels in a multi-walled carbon nanotube shell.

  • Properties of carbon nanotubes loop antenna at Terahertz range

    It is the first time this paper investigates the fundamental characteristics of the loop antenna formed single-walled carbon nanotubes from 1.0~10 terahertz frequency region using finite integral methods. The armchair single- walled carbon nanotubes can be considered due to their metallic conducting. The surface current dense, electric field and magnetic field distribution, scattering coefficient, input admittance, radiation patterns and gain are presented and compared to carbon nanotubes dipole antenna with the same size of the perimeter of the loop antenna. The results demonstrate that carbon nanotubes loop antenna with a radius of 15 μm takes on the resonant frequency properties from 7.35 terahertz to 7.46 terahertz in the center frequency of 7.4 terahertz, corresponding scattering coefficient less than -10dB. The maximum gain of carbon nanotubes loop antenna is 5.7 dB. All results is can be used for the design of carbon nanotubes antenna in the terahertz region.

  • Piezoresistive pressure sensor based on carbon nanotubes/epoxy composite under cyclic loading

    Pressure sensors are highly required and used in many engineering applications. However, commercial pressure sensors have many disadvantages in terms of sensitivity, durability and scalability. Therefore, carbon nanotubes/polymer based nanocomposites are intensively being used for force/pressure sensing application owing to their remarkable piezoresistive properties. In this paper, we report an easy-synthesized piezoresistive pressure sensor based on multi-walled carbon nanotubes (MWC-NTs)/epoxy based nanocomposites. The proposed sensor exhibit pressure sensitivity up to -0.7% up to 670 kPa with the sensitivity of 13 kPa-1, high durability and small hysteresis over 100 cycles. The proposed sensor can be widely used and integrated in engineering systems where pressure/force information is needed.

  • Sensitive <formula formulatype="inline"><tex>${\rm NH}_{3}{\rm OH}$</tex></formula> and HCl Gas Sensors Using Self-Aligned and Self-Welded Multiwalled Carbon Nanotubes

    We present the design and fabrication of sensitive and responsive and HCl sensors based on multiwalled carbon nanotubes (MWCNT). The sensors consisted of self-aligned and self-welded MWCNT bridges grown between 18 mum-high silicon posts with 2-6 mum gaps using metal-catalyzed chemical vapor deposition technique (CVD). The 5-10 MWCNTs spanning the gap showed excellent ohmic electrical contacts and mechanical bonding strengths in excess of 0.1 muN/CNT. The conductivity of the MWCNTs changes as oxidizing and reducing gases are physically adsorbed on their large surface-to-volume ratio structures. Since carbon atoms in CNTs do not have any dangling bonds, the interaction between CNTs and gas molecules does not lead to chemical reactions and the process is reversible. Provided that the starting MWCNTs have high resistivity, they have nearly exponential sensitivity in detecting gases and owing to their very small volume and reversible interaction with gases, they can have a very fast response time. In our experiment, upon exposure to ammonia and hydrochloric gases at room temperature, the electrical conductivity of the self-welded carbon nanotube bridges exhibited a dramatic change. The growth process, test results, and the gas sensitivities will be discussed.

  • The preparation of carbon nanotubes by DC arc discharge process using Xylene-Ferrocene as a floating ctalyst presusor

    A new synthesizing method, a floating catalyst technique, was studied to produce carbon nanotubes in a dc arc discharge process. The Xylene-Ferrocene (catalyst precursor) was directly introduced into the DC arc chamber by carrying gas. Experimental results showed that multi-walled carbon nanotubes (MWNTs) and single-walled carbon nanotubes (SWNTs) can both be synthesized using this technique. The quantity of synthesized MWNTs and SWNTs varied depending on the process conditions, such as the flow rate of ferrocene, pressure, process current and voltage. The yield of SWNTs was improved by increasing the flow rate of Xylene-Ferrocene due to the high density of the catalyst precursor but decreased by lowering process current due to poor activation ability of catalyst.
