Graphene, the newest member of the carbon’s family, has proven its efficiency in improving polymers’ resistance against photodegradation, even at low loadings equal to 1 wt% or lower. This protective role involves a multitude of complementary mechanisms associated with graphene’s unique geometry and chemistry. In this review, these mechanisms, taking place during both the initiation and Exposure to UV light can also make plastic parts more brittle and susceptible to breakage, cracking, deformation, or disintegration. While almost no material is entirely resistant to UV light, some can absorb UV radiation. Adding stabilizers or additives can improve UV resistance for plastics that can’t absorb UV light. These non-UV-resistant Aromatic amino acids (such as tyrosine, phenylalanine, and tryptophan) could absorb UV-B radiation; therefore, these are more vulnerable to the direct effects of UV-radiation [49,50]. Glutamate is an important substrate for amino acid metabolism and is used for the synthesis of other amino acids; in consequence, the content of glutamate tends
While many pure plastics cannot absorb UV radiation, the presence of catalyst residues and other impurities will often act as receptors, causing degradation. The Electromagnetic Spectrum What is the effect of UV light on plastics? The UV light breaks down the chemical bonds in a polymer by photodegradation.
Similarly, in PE and PP the presence of chromophores in PVC due to impurities can absorb UV radiation and generate free radicals. The free radicals form hydroperoxides that can break the double bonds of the backbone chain and generate smaller degradation products (Law 2016; Yang et al., 2018).
Dose We Use Glass/plastic? For training purpose in educational institute we can use the glass cuvette but due to the property of glass to absorb UV light mostly below 350nm make it not suitable W2Lno4.
