―This study studies on the physical property of MWNT/PU composit e film for electrostatic dissipation (ESD) function by dispersing multi-wall carbon nanotubes (MWNT) in dimethylfor mamide (DMF) and by combining it with polyurethane(PU). For this purpose, four kinds of MWNT were selected and the composit e films were made by dispersion processing, and their physical properties were measured and investigated in terms of electrica l conductivity. For dispersion parameters, four MWNT contents(0 .5, 1, 2, 5wt%) and two dispersion times(30min, 120min) were select ed. The dispersion property and the electrical conductivity of MWNT/PU film was measured using a UV-Vis spectrometer and condu ctivity measuring apparatus. Finally, their physical properties according to the dispersion conditions were analyzed and discus sed with various processing conditions.
