ultraviolet degradable plastics, biopolymers, microspherical glass, degradation promoters, electrochemical impedance spectroscopyAbstract
This study investigates the effect produced by microspherical glass additives on ultraviolet-induced degradation of polymethyl methacrylate films using electrochemical impedance spectroscopy. Ultraviolet exposure accelerates film degradation, which is enhanced by microspherical glass through light concentration and catalytic activity, promoting photoionization and free radical formation. Electrochemical impedance spectroscopy shows reduced impedance and curve flattening in films with microspherical glass after prolonged ultraviolet exposure, indicating faster coating failure than in pure polymethyl methacrylate. These findings support microspherical glass as a safe degradation promoter, aiding sustainable plastic design.
