摘要：
Hybrid polymer-semiconductor nanostructured films were obtained by co-electrodeposition of poly(vinyl acetate-co-crotonic acid) and CdS or CdTe nanoparticles (NPs) stabilized with 1-thioglycerol (TGL) or thioglycolic acid (TGA). Composite films were enriched with negatively charged NPs stabilized with TGA. Relative uptake of these NPs increased with electrodeposition time and increase in NP concentration in solution, while the variation in electric field had little effect on NP electrodeposition. No substantial aggregation or NP growth occurred in the electrodeposition process and during film formation. Electrodeposited films showed higher quality and better properties of NPs compared to the cast films obtained from the same solutions. Electrodeposition of hybrid polymer- semiconductor films on patterned substrates was demonstrated.
