High-Strain PVC Film Plasticized by TiO₂ Nanoparticles

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.
