Processing And Characterization Of Helical Carbon Nanotube Paper Based Thermoplastic Nanocomposite Films

Abstract

Straight carbon nanotubes have been widely studied for their capability of enhancing the mechanical, electrical and thermal properties of a host polymer matrix. However, there is a lack of research on the incorporation of helical carbon nanotube into the polymer matrix. The peculiar helical configuration of carbon nanotubes could greatly improve the interfacial bonding between carbon nanotubes and polymer matrix. In this study, helical carbon nanotube paper-based thermoplastic polyurethane nanocomposite films were fabricated through spray deposition process. Helical carbon nanotube paper was sprayed onto a substrate first and then thermoplastic polyurethane resin was sprayed on the paper to make the final nanocomposite films. This process is capable of making a thin sheet of thermoplastic nanocomposites with high carbon nanotube loadings. The smallest thickness can be 40μm. Electrical resistivity measurement showed enhanced electrical properties of resulting nanocomposite films. Thermo gravimetric analysis indicated that helical carbon nanotubes effectively improved the thermal stability of thermoplastic polyurethane.
