A Comparative Study of the Photostabilization of Polyvinyl Chloride with Nano and Micro Nickel Oxide
AI summary Read the abstract
Researchers examined nano and micro nickel oxide (NiO) as photostabilizing additives for polyvinyl chloride (PVC) films, synthesizing NiO nanoparticles via chemical methods and characterizing them by XRD and FESEM, then testing composite PVC-NiO films under UV irradiation at doses from 0 to 300 hours. FTIR and UV-VIS spectroscopic analyses revealed differences in photodegradation behavior between nano and micro NiO additives, with implications for producing photodegradable or photostabilized PVC materials.
NiO nanoparticle synthesis by chemical method and characterized by XRD with crystal size 11.72 nm and grain size 13 nm from FESEM image also NiO micro used ,two NiO as an additive to evaluate the possibility of producing photodegradable polymers, the practical application of solid-phase photocatalytic degradation of polyvinyl chloride (PVC- NiO composite films) was investigated. PVC has a negative impact on the environment since its polymer degrades slowly, yet it has a wide range of industrial applications and the amount used shows no evidence of diminishing use. Thus, a synthesis of modified PVC- NiO micro and nano has been studied with 0, 50, 100, 150, 200, 250, and 300 (hours) as irradiation time and a number of spectroscopic analyses such as FTIR and UV-VIS. Additionally, the effects of adding nanostructures to PVC chains on optical stability testing procedures were examined through indices (ICO, IPO, and IOH), weight loss measurements, UV and viscosity.

Application of Metal Oxides Nanoparticles to Enhance Ultraviolet Light Resistance of Polyvinyl Chloride Films
AI summary Read the abstract
Metal oxide nanoparticles were applied to plastic films to investigate whether they could accelerate UV-driven degradation in environmental conditions. The nanoparticles acted as photocatalysts, generating reactive oxygen species under UV light that broke down polymer chains faster than UV exposure alone. This approach offers a potential strategy for reducing the persistence of plastic waste in outdoor environments.
