Facile fabrication of polycaprolactone/h-MoO3 nanocomposites and their structural, optical and electrical properties

摘要: Hexagonal molybdenum oxide (h-MoO3) nanocrystals with a flower-like hierarchical structure were successfully incorporated into polycaprolactone (PCL) matrix by simple solution casting technique. Initially, the PCL was prepared catalytic ring-opening polymerization (ROP) of e-caprolactone (e-CL) under solvent free condition. Thiosemicarbazide and 4-phenylthiosemicarbazide based metal (Zn2+ Cu2+) complexes employed as catalysts for ROP e-CL. The reaction conditions optimized in detail. resultant used to fabricate PCL/h-MoO3 nanocomposites. h-MoO3 three different weight percentages (1, 3 5 wt%) chosen. structural, functional morphological properties nanocomposites investigated various spectroscopic microscopic techniques. merit realized from improved AC conductivity, dielectric optical compared pure PCL.
