Abstract

A comparison investigation was made on thermal decomposition behaviors of poly (lactic acid) (PLA) hybrids with two different metal oxides of TiO2 and ZnO by means of thermogravimetric analysis. Experimental measurements were conducted with a scanning rate of 5–20 K/min in nitrogen. Abstracted from non-isothermal decomposition data, thermal degradation temperatures of PLA/metal oxide hybrids were obtained and compared so as to investigate the effects of two metal oxides. The activation energy Ea for PLA thermal decomposition was calculated by using the Kissinger method and the results implied that the metal oxide added had greatly changed the PLA thermal stability and the service lifespan was predicted based on the Ea values.
