Sb 2 O 3 nanoparticles were prepared using CMC as the stabilizing agent. The nanocomposite was fabricated with Sb 2 O 3 /CMC nanoparticles as the filler in a GPS matrix. Characterization of Sb 2 O 3 /CMC nanoparticles revealed that Sb 2 O 3 (about 84 wt.‐%) was encapsulated by CMC (about 16 wt.‐%) with the size of about 30–50 nm. Because there was good interaction between the Sb 2 O 3 /CMC filler and the GPS matrix, Sb 2 O 3 /CMC nanoparticles could be uniformly dispersed in the GPS matrix at a low filler loading level, resulting in obvious improvement in tensile strength and UV absorbance, and in the resistance of water vapor permeability. However, introduction of the nanoparticles into the matrix, decreased the elongation at break and the thermal stability of the nanocomposites.
