Abstract

Abstract: PLA and PLA/MMTHTCC nanocomposites were synthesized via ringopening polymerization with zinc lactate as a green catalyst. The composite was characterized using FTIR spectrum, Xray diffraction (XRD), TG analysis ,scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The thermal degradation kinetics was analyzed using Kissinger′s method and Ozawa′s method, and the apparent activation energy was obtained. Because a fraction of PLA was intercalated into MMTHTCC, the PLA/MMTHTCC composite possessed a higher thermal degradation activation energy than that of neat PLA, the peak temperature of thermal decomposition of PLA/MMTHTCC was 35.18 ℃ higher.

Key words: poly lactic acid, green synthesis, intercalation composites, Characterization, thermal degradation
