title: Preparation of O2 Plasma Treated Polycaprolactone/Nano TiO2 Composites and In Vitro Bioactivity.
abstract: Polycaprolactone (PCL)/TiO2 composite films (PTCFs) were prepared by a solvent casting method at various concentrations of TiO2 (1, 3, 5, and 10 wt%) and then treated using oxygen plasma. The hydrophilicity of the oxygen plasma treated PTCFs increased as the treatment time was increased, due to the oxygen induced production of polar species at the surface of the PTCFs. In vitro bioactivities of the composite films were examined by immersion in simulated body fluid for up to 7 days. It was found that the oxygen plasma treatment significantly influenced the in vitro bioactivity of the PTCFs.
