Fabrication and characterization of ZnO-NP-doped gelatin/PEG/chitosan composite films for the pharmaceutical and photocatalytic degradation of dyes
Composite films of gelatin/polyethylene glycol/chitosan (GPC) doped with varying amounts (0.5–2.5% w/w) of zinc oxide nanoparticles (ZnO-NPs) were prepared by a solution casting/ultrasonic method. The ZnO-NPs with average crystallite sizes of 10.20 nm were successfully synthesized by the co-precipitation method, and th...
