Abstract
The low strain and toughness of tetrahydrofuran (THF)-cast poly(vinyl chloride) (PVC) film were mitigated by introducing TiO2 nanoparticles at loading below 0.8 wt%. The thus obtained PVC/TiO2 composite showed superb elongation at break (383%) and toughness (64.7 J m-3) due to modified molecular interactions between nanoparticles and PVC chains.

Tetrahydrofuran(THF)를 이용하여 제조한 poly(vinyl chloride)(PVC) 필름의 낮은 인장률과 인성이 TiO2 나노입자를 0.8 wt% 미만의 농도로 첨가하였을 때 향상되었다. 제조된 PVC/TiO2 복합재료는 383%의 우수한 인장률과 64.7 J m-3의 인성을 나타냈는데, 이는 PVC 고분자 사슬과 나노입자 사이에서 분자간 인력이 작용하기 때문이다.

Keywords: poly(vinyl chloride); TiO2; inorganic nanofiller; high strain
