Biodegradable polymer blends of poly(lactic acid) (PLA) and poly(butylene adipate- co-terephthalate) (PBAT) and their hybrids with trisilanolphenyl POSS(TSP-POSS) were prepared by a melt mixing in an internal mixer. Phase morphology, mechanical, thermal and rheological porperties of the hybrids were investigated by means of FE-SEM, tensile test, DSC, DMA, Izod impact test and small amplitude oscillatory shear rheometry. It was shown that addition of small amount of POSS into the PLA/PBAT blend improved the tensile strength, tensile modulus as well as izod impact strength. |
