Polyamide 12/Trisilanolphenyl-POSS (PA 12/POSS) composites were prepared via melt-compounding. WAXD results indicated that PA 12 crystallized into -form when slowly cooling from melt and the presence of POSS did not influence the crystalline structure of PA12. Both PA 12 and PA 12/POSS composites underwent Brill transitions when they were heated from room temperature to melt point. Real time-FTIR patterns showed that an absorption band at 697 cm-1 ascribed to Amide V ( ) mode was emerged along with the disappearance of Amide VI ( ) band at 628 cm-1 with the increase of the temperature for PA 12 and PA 12/POSS composites, which suggested that the -form crystalline has transformed into form. The Young’s modulus of the composites increases with the POSS loadings increasing and is nearly twice times of that of pure PA12 when 5.0 wt% POSS was added.
