nanotube (MWNT) with different MWNT contents were mixed and dispersed, and their characteristics related to the dispersion

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.},
