Abstract

Various polyvinyl chloride thin films containing captopril and several metal (cobalt, copper, and nickel) oxide nanoparticles were produced. Low concentrations of both captopril (0.5% by weight) and metal oxides (0.01% by weight) were used to produce transparent films. The role played by both captopril and metal oxide nanoparticles as ultraviolet blockers for photodegradation of polyvinyl chloride was investigated. The addition of both metal oxides and captopril to polyvinyl chloride films enhances the stability of polymeric materials more than captopril alone. Observation of weight loss, changes in infrared spectra and surface morphology of blends on irradiation showed that a combination of captopril and nickel oxide nanoparticles efficiently blocks ultraviolet light and provides a high level of protection to polyvinyl chloride.
