Preparation and Properties of Nanocomposites Based on Poly (Lactic Acid)and Modified TiO2

摘要：

In this study,poly(lactic acid)(PLA)-TiO2 nano particle nano composites were prepared and the severe aggregation of TiO2 nano particles in polymer matrixwere reduced by themodification of TiO2 surface with propionic acid and n-hexylamine.The resulting products were characterized by FT-IR,DSCand SEMtechniques so as to have a better understanding of bondingbetween the polymer and nano particles.All of nano composites with a wide range of TiO2 additionexhibit the high transparency.SEM micrographs of the nano composites showed of the TiO2 nano particles were uniformly dispersed in polymer matrices.Photodegradation of PLA-TiO2 nano particle nano composites were also investigated.The results indicated that nano composites could be efficiently photodegraded by UV irradiation in comparison with pure PLA.
