Preparation and characterization of biodegradable polycaprolactone/ titanate nanotubes composites

The objective of this study was modification of biodegradable polycaprolactone with TiO2 nanotubes as filler in the purpose to improve processing and /or other desired properties. Composites of biodegradable PCL with 0.5, 1.0 and 2.0 wt. % titanate nanotubes were prepared by melt mixing using a laboratory Brabender mixer. Final specimens for all investigations (size 40 mm x 12mm x 1.5 mm) were obtained by compression molding the materials in a hot-plate of a laboratory hydraulic press Dake Model 44-226 at 140°C. TiNT was prepared by hydrothermal synthesis from nano TiO2 particles and dried TiNT nanopowder was employed in preparation of PCL/TiNT composites. The effects of TiNT on the thermal properties (DSC), viscoelastic properties (DMA) and morphology (SEM, LM) were studied. From DSC results, Tm slightly increased, Tc increased while crystallinity (c) decreased with TiNT content in compare with neat PCL. DMA measurements show that the Tg and storage modulus increased in PCL/TiNT composites. SEM and LM results showed that the aggregates were formed.
