Abstract
Poly(butylene adipate-co-terephthalate) (PBAT) and thermoplastic starch (TPS) were blended by using maleic anhydride (MA) as a compatibilizer. Preferentially, TPS could be reacted with MA to obtain maleated thermoplastic starch (MTPS). Then PBAT/MTPS blends were blown films using blown technique. From dynamic mechanical analysis, the shifting of the glass transition temperatures toward each other suggested that PBAT was partially miscible with MTPS. From wide angle X-ray diffraction analysis, the degree of crystallinity of PBAT/MTPS films was decreased with increasing MTPS content. From rheological measurements, the melt elasticity and viscosity of the PBAT/MTPS blends increased. It was benefit to extrude blend and blow film. The contact angle values of bipolar liquid water were range from 100.2 to 77.7 ° decreased with increasing MTPS content from 0 to 50 %. The PBAT/MTPS films could satisfy the requirement for applying in our life.
