Poly(butylene adipate-co-terephthalate)(PBAT) is a promising biodegradable polymer based on fossil resources, with high flexibility and softness. However, the price of PBAT is too high, thus blending with low-price resins is required. Starch is one of the most abundant natural food sources, has been considered an attractive biopolymer filler because of its low cost, high biodegradability. In this study, thermoplastic starch(TPS) is prepared by plasticizing tapioca starch with glycerol and maleic anhydride in order to enable melt processing, then blended with PBAT to achieve PBAT/TPS composites. And effect of maleic anhydride on TPS and performance of PBAT/TPS composite are evaluated by Fourier transform infrared spectroscopy(FT-IR), melt flow index(MFI), scanning electreon microscopy(SEM), water contact angle, thermal and mechanical analysis. The experimental results show that maleic anhydride improve processability of TPS and promote interfacial adhesion between TPS and PBAT phase. |
