Poly(butylene succinate)(PBS)/TS-1 zeolite hybrid composite (PTHC) were synthesized without conventional catalyst. The objective of this study was to investigate how can affect the water uptake feature of TS-1 zeolite on physical, rheological properties and enzymatic hydrolysis for PTHC. TS-1 zeolite can act as catalyst as well as reinforcement filler, resulted that PTHC showed remarkable increase in physical properties. The rheological properties of PTHC with high zeolite contents showed low values of complex viscosity compared with PTHC with low zeolite contents due to volatilization of water released from the zeolite pores. In case of enzymatic hydrolysis for several weeks, the enzymatic hydrolysis rates of PTHC were significantly accelerated with increasing TS-1 zeolite contents compared with Homo PBS. This result indicated that TS-1 zeolite can act as the role of carrier for enzyme activation, resulting enzymatic hydrolysis occur from amorphous area of surface into inside film. |
