Fabrication of uniform thin coatings of multi-walled carbon nanotubes (MWCNTs) by electrophoretic deposition (EPD) on semiconductor (silicon) substrates with 3-aminopropyl-triethoxysilane (APTES) surface functionalization has been studied extensively in this report. The gradual deposition and eventual film formation of the carbon nanotubes (CNTs) is greatly assisted by the Coulombic force of at...

This study proposes the use of carbon nanotubes (CNTs) as reinforcement to enhance the mechanical properties of a polylactide-caprolactone copolymer (PLC) matrix. Biological interaction of PLC-CNT composites with human osteoblast cells is also investigated. Addition of 2 wt % CNT shows very uniform dispersion in the copolymer matrix, whereas 5 wt % CNT shows severe agglomeration and high porosi...

a fiber coating from polyaniline (pani) was electrochemically prepared and employed for solid phase micreoextraction (spme). the pani film was directly electrodeposited on the platinum wire surface using cyclic voltametry (cv) technique. the same method was applied for the preparation of spme fiber coated by polyaniline multiwalled carbon nanotubes (pani/mwcnts) composite. the concentration of ...

Conventional micro-fiber-reinforced composites provide insight into critical structural features needed for obtaining maximum composite strength and stiffness: the reinforcements should be long, well aligned in a unidirectional orientation, and should have a high reinforcement volume fraction. It has long been a challenge for researchers to process CNT composites with such structural features. ...

carbon nanotube (cnt), due to extraordinary mechanical properties, is an effective stiffener as reinforcement in resin for fabricating of nanocomposites. it is demonstrated by adding a small amount of cnt to the matrix, the elastic modulus of matrix increases remarkably. in this paper, the elastic modulus of cnt reinforced nanocomposites is obtained two-dimensionally using a finite element meth...

In this article, direct coating of ZnO on PECVD-grown multi-walled carbon nanotubes (MWCNTs) is achieved using atomic layer deposition (ALD). Transmission electron microscopy investigation shows that the deposited ZnO shell is continuous and uniform, in contrast to the previously reported particle morphology. The ZnO layer has a good crystalline quality as indicated by Raman and photoluminescen...

We report correlated measurements of cyclic loading behavior with electrical resistance of energystoring carbon nanotube (CNT) springs under tensile loading. Tests are conducted on fibers of MWCNTs fabricated from 6 mm tall forests. The highest measured strength and stiffness of the fibers are 0.5 N/tex and 24 N/tex. The resistance and stress responses of the fibers during loading to failure an...

This paper discuss about the critical review on design of carbon nanotube based MEMS piezoresistive pressure sensors, use of different types of carbon nanotubes such as multi-walled carbon nanotubes (MWCNTs), single-walled carbon nanotubes (SWNTs) and vertically aligned carbon nanotubes (VANTs), sensing mechanism, applications, etc. The structural deformation of the piezoresistive nano structur...

The objective of this paper is to provide a fracture mechanics characterization mortar nanocomposites reinforced with multiwall carbon nanotubes (MWCNTs). critical stress intensity factor, KIc, the strain energy release rate, GIc, effective crack length, ac, and tip opening displacement, CTODc are determined using three-point bend specimens. It was established that reinforcement MWCNTs provides...

BACKGROUND Removal of pathogens from water is one way to prevent waterborne illness. In this paper, we developed dual functional carbon nanotube (CNT) modified filters for bacterial capture and inactivation, utilizing multi-walled CNTs (MWCNTs) to coat on commercially available filters and making use of the exceptional adsorption property of CNTs to adsorb a natural antimicrobial peptide-nisin ...
