摘要：The novel biodegradable poly (epsilon-caprolactone)/TiO2 nanocomposites were prepared by in situ polymerization of epsilon-caprolactone in the presence of modified-TiO2 nanoparticles as initiator. The molecular weight of poly (epsilon-caprolactone) (PCL) matrix was dependent on the amount of the TiO2 fillers. The incorporation of TiO2 did not significantly affect the crystalline structure of PCL. An astounding nucleating effect of TiO2 on PCL crystallization was observed. The enhanced thermal stability of PCL nanocomposites was observed.
