采用熔融挤出法和溶剂溶解法制备了聚乳酸（PLA）/蒙脱土（MMT）和PLA/蒙脱土（PLA/MMT）复合材料。考察了有机/无机配比和无机物种类对复合材料性能的影响。通过TGA和DSC对复合材料的热稳定性进行了评价，并通过SEM对复合材料的形貌进行了表征。通过动态力学分析（DMA）评价弹性模量。与纯PLA相比，PLA/无机复合材料的力学性能和热性能均有显著提高。
In this study polylactide (PLA)/perlite and PLA/montmorillonite (MMT) composites were prepared by melt extrusion and solvent dissolution methods. The effects of organic/inorganic ratios and the kind of inorganic compounds on the characterization of the composite materials were investigated. The thermal stability of the organic–inorganic composite materials was evaluated by TGA and DSC, and the morphology of these composites was measured as SEM images. The modulus of elasticity was evaluated by Dynamic mechanical analysis (DMA). The PLA/inorganic composites exhibited remarkable improvement of mechanical and thermal properties when compared with those of the pure PLA.
