Study on the Properties of Nano-TiO2/Polybutylene Succinate Composites Prepared by Vane Extruder

Different proportions of nanoscale TiO2 (nano-TiO2)-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 TiO2 addition. TiO2 almost has no effect on the crystallization and melting behavior of PBS. Nevertheless, the introduction of TiO2 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 TiO2 addition. POLYM. COMPOS., 35:53-59, 2014. (c) 2013 Society of Plastics Engineers
