Abstract

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 × 108 Ω·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.


안티몬이 도핑된 산화주석(ATO)으로 충전된 폴리(4-메틸-1-펜텐)(PMP) 전기전도성 나노복합체를 제작하여 전기적, 열적, 기계적 특성 및 미세구조 연구를 진행하였다. 또한 제작된 PMP/ATO 나노복합체 필름의 전자선 조사에 따른 물성 변화를 비교하였다. 용액 혼합법에 의해 형성된 나노복합체의 퍼콜레이션 임계치는 대략 25 wt%였으며, 이 때의 체적저항 값은 5.1×108 Ω·cm을 나타냈다. 전자선 조사량이 증가함에 따라 PMP/ATO 나노복합체의 인장 및 열적 특성은 크게 변했지만 상대적으로 열안정성과 체적저항에는 큰 영향을 미치지 않았다.
