Effect of clay on melt crystallization, crystallization kinetics and spherulitic morphology of poly(trimethylene terephthalate) nanocomposites

- PTT/clay exfoliated nanocomposites films were prepared by novel two-step approach.
- It has been shown that the incorporation of clay accelerates the rate of crystallization and increases the total crystallinity of PTT nanocomposites compared to neat PTT.
- FTIR results showed that the amorphous trans conformation transforms into the crystalline gauche conformation with increasing clay content and crystallization temperature.
