Manufacturing and characteristics analysis of PU/MWNT film for electrosatic dissipation

Abstract

This study surveys the characteristics of the nanocomposite film for PU/MWNT. For this purpose, several kinds of PU/MWNT nanocomposite films were prepared with four kinds of MWNT, MWNT contents and two kinds of dispersion times and ESD (Electrostatic Dissipation) films composed with polyurethane (PU) block copolymer and selected multi-walled carbon nanotube (MWNT) were also prepared by disperse processing with various MWNT contents and dispersion times, and their mechanical and chemical properties were investigated with electrical conductivity. The tensile properties and chemical properties of PU/MWNT nanocomposite films were measured using UV-visible spectrometer and discussed with the manufacturing conditions of nanocomposite film. Furthermore, the PU/MWNT films were made by dispersing with five kinds of CNT content and six kinds of dispersion time under the DMF (dimethylformamide) solution, and the mechanical properties of the PU/MWNT films were analyzed by Instron and discussed with various dispersion conditions.
