Atmospheric Pressure Plasma Functionalization of Dry-spun Multi-walled Carbon Nanotubes Sheets and its application in CNT-Polyvinyl Alcohol (PVA) Composites
Published online by Cambridge University Press: 31 May 2013
Abstract
Robust sheets comprised of aligned multi-walled carbon nanotubes (MWNTs) drawn from spin-able carbon nanotube (CNT) arrays were developed. Surface modification of these sheets was carried out via an atmospheric pressure plasma jet as a post-treatment process. Helium/Oxygen plasma was utilized to produce carboxyl (-COO-) functionality on the surface of the nanotubes. Raman Spectroscopy, X-Ray Photoelectron Spectroscopy (XPS) and Fourier Transform Infrared (FTIR) Spectroscopy confirm the presence of functional groups on the nanotube surface. Composite laminates made from functionalized CNT sheets in a polyvinyl alcohol (PVA) matrix demonstrate increase in tensile strength over those made with pristine sheets used as reinforcement material.
