To improve the miscibility of native rice starch granules and poly(butylene adipate-co-terephthalate)(PBAT), rice starch was hydrolyzed by a mixture of α-amylase and amyloglucosidase. The obtained porous rice granular starch was then mechanically blended with PBAT by single screw extruder. Many pits and holes on the surface of starch granules were observed by scanning electron microscopy (SEM). The rough surface of the rice starch granules improved the compatibility of the polymers in the blends, which consequently increased the tensile strength and the elongation at break. In addition, SEM also revealed that the porous granules were homogeneously distributed in the polymer matrix with no appearance of gaps.

In order to confirm the feasibility of porous rice starch granules and PBAT blends as biodegradable composites, their degradability were carried out. Enzymatic degradability evaluation showed that α-amylase degradation of starch increased as the starch content in the blend increased. Burial test of the blends for 1-4 months was carried out and the rate of degradation of the PBAT/porous starch blend was confirmed to be slower than those of PBAT/native rice starch blend. Observation of the film blends structure by scanning electron microscope revealed that the starch was dispersed in a PBAT matrix. Furthermore, changes in the film surface after enzyme treatments were observed. The results obtained from the degradability of the porous starch granules and PBAT blends showed that this bio-composite was relatively slow, regarding as controllable degradation material.
