Ageing of plasticized poly(lactic acid)/poly(β-hydroxybutyrate) blend films under artificial UV irradiation and under real agricultural conditions during their application as mulches‡

AbstractA number of poly(lactic acid-co-glycolic acid)/polyurethane (PLGA/PU) blend films with various PU mole contents were prepared by casting the polymer blend solution in chloroform. The surface morphologies of the PLGA/PU blend films were studied by scanning electron microscopy (SEM). The thermal, mechanical and chemical properties of the PLGA/PU blend films were investigated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), tensile tests and surface contact angle tests. The results revealed that the introduction of PU could markedly modify the properties of PLGA films.

In this study, poly (lactic acid) (PLA)-TiO2nano particle nano composites were prepared and the severe aggregation of TiO2nano particles in polymer matrixwere reduced by themodification of TiO2surface 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 TiO2additionexhibit the high transparency. SEM micrographs of the nano composites showed of the TiO2nano particles were uniformly dispersed in polymer matrices. Photodegradation of PLA-TiO2nano particle nano composites were also investigated. The results indicated that nano composites could be efficiently photodegraded by UV irradiation in comparison with pure PLA.
