Study on the properties of nano‐TiO₂/polybutylene succinate composites prepared by vane extruder

Abstract

Different proportions of nanoscale TiO 2 (nano‐TiO 2 )‐filled polybutylene succinate (PBS) composites were prepared by vane extruder. The crystalline, thermal, dynamic viscoelastic, mechanical, and UV‐resistance properties of the composites were studied, and X‐ray diffraction, differential scanning calorimetry, and thermogravimetric analysis were conducted. Results show that the crystalline structure of the PBS composites did not change with TiO 2 addition. TiO 2 almost has no effect on the crystallization and melting behavior of PBS. Nevertheless, the introduction of TiO 2 has improved the thermal stability, tensile modulus, flexural modulus, and flexural strength of the PBS composites. The UV resistance of the composites has also been significantly enhanced with TiO 2 addition. POLYM. COMPOS., 35:53–59, 2014. © 2013 Society of Plastics Engineers
