Abstract This paper reports the photo degradation of polystyrene (PS) by using zinc oxide (ZnO) as photo catalyst. Virgin PS is not responsive to degradation by ultra violet (UV) light because of the presence of phenyl rings in its repeating units. ZnO acts as an UV absorber and helps in transferring the absorbed energy to various bonds of PS and causes degradation. The concentration of ZnO followed by the dispersion within the PS matrix has been found to be the key as the maximum weight loss… Expand

Photo-catalytic and biotic degradation of polystyrene packaging film: Effect of zinc oxide photocatalyst nanoparticles and nanoclay.
TLDR
Synergistic effect of zinc oxide nanoparticles as photocatalyst and organonanoclay (ONC) as biodegradable promoter on the degradation of polystyrene (PS) film was investigated and higher photo- and biodegradation efficiency of PS-ONC-ZnO nanocomposite was found. Expand
XPS studies of poly(acrylic acid) grafted onto UV photo-oxidized polystyrene surfaces
UV photo-oxidation of polystyrene was achieved with 253.7 and 253.7/184.9 nm radiation in the presence of an atmospheric pressure of oxygen and analyzed by X-ray photoelectron spectroscopy as a… Expand
Vacuum UV photo-oxidation of polystyrene
Abstract Polystyrene (PS) was treated with vacuum UV (VUV) (λ = 104.8 and 106.7 nm) photo-oxidation and X-ray photoelectron spectroscopy detected a controlled increase in the atomic percentage of… Expand
Surface characterization of polystyrene treated with ozone and grafted with poly(acrylic acid)

Styrene monomer migration from polystyrene based food packaging nanocomposite: Effect of clay and ZnO nanoparticles.
TLDR
Organoclay and zinc oxide nanoparticles (ZnO-NPs) were used for decreasing of the SM migration into food simulants (10 and 50% ethanol) and a used GC-FID method for measuring of the migrated SM showed good precision and accuracy. Expand
