| Abstract: | This study explored the thermal behavior of PLLA–PPG nanocomposite with added organoclay. The modified clay was evenly dispersed into the matrix of LPG1000 to synthesize the nanoscale polymer. Thermogravimetric analysis and differential scanning calorimetry were used to measure the thermal properties of the PLLA–PPG copolymers. Wide-angle X-ray diffraction was used to identify the crystal structure of PLLA–PPG copolymer. The crystal growth of PLLA–PPG copolymer with various proportions of added clay was observed by using polarized optical microscopy and transmission electron microscopy. The results show that adding clay could enhance the thermal stability of LPG1000 and significantly change its crystal property. |
