Electrical, Thermal, Mechanical and Morphological Properties of Poly(4-methyl-1pentene) Nanocomposites Filled with Electrically Conductive Tin Dioxide

초록

We fabricated electrically conductive nanocomposites consisting of poly(4-methyl-1-pentene) (PMP) filled with antimony-doped tin dioxide (ATO) nanoparticles and investigated their electrical, thermal, mechanical properties, and microstructure. Additionally, the effects of electron beam irradiation on the properties of the prepared PMP/ATO nanocomposite films were compared. The percolation threshold of the nanocomposites formed by the solution-mixing method was about 25 wt%, and the corresponding volume resistivity was 5.1 x 10(8 )Omega<middle dot>cm. With increasing electron beam irradiation dose, the tensile and thermal properties of the PMP/ATO nanocomposites changed significantly, while the thermal stability and volume resistivity were relatively unaffected.
