abstract = {This study examines the electrical conductivity of multi-walled carbon nanotube (MWNT) /polyurethane (PU) nanocomposites film 
according to the dispersion conditions. For this purpose, various kinds of polyurethane block copolymer (PU)/multi-wall carbon 
nanotube (MWNT) with different MWNT contents were mixed and dispersed, and their characteristics related to the dispersion 
were investigated. Multi-walled carbon nanotubes (MWNT) are of interest in many areas of nanotechnology and used in a number 
of novel applications. However effective dispersion remains a problem and one solution is to functionalize the nanotubes. In this 
work, MWNTs are functionalized using an oxidative technique, including dry thermal treatment. The dispersion variation of the 
PU/MWNT nanocomposite films with MWNT content ranging from 0.1 ∼ 5.0 wt% was examined. The various characteristics of the 
dispersed PU/MWNT nanocomposite film were characterized using thermo gravimetric analyser (TGA), scanning electron 
microscope (SEM) and measuring instrument of electrical conductivity. The degree of dispersion of PU/MWNT nanocomposite 
films according to the dispersion conditions was shown in various situations. The bad dispersion of PU/MWNT film was revealed 
during the phase separation between PU matrix and MWNT. Also PU/MWNT nanocomposite film shows good electro-conductivity 
on its surface because MWNT was collected on the surface of composite film due to its low density.},
