What does UV-Vis spectroscopy identify?
UV radiation causes photooxidative degradation which results in breaking of the polymer chains, produces free radical and reduces the molecular weight, causing deterioration of mechanical properties and leading to useless materials, after an unpredictable time.
What is UV vis spectroscopy of polymers?
UV-Vis spectroscopy is a valuable technique for analyzing polymers, providing insights into their electronic structure, composition, and molecular interactions. When applied to polymers, UV-Vis spectroscopy is used to study the absorption of ultraviolet and visible light by polymer molecules.
What is the effect of UV on polymers?
UV-Vis spectroscopy is based on the interaction between light and matter. When light passes through or is absorbed by a molecule, it can cause the molecule to vibrate. The wavelength of light that is most strongly absorbed by a molecule is called the absorption maximum.
What is the purpose of the UV-Vis spectroscopy?
Ultra Violet-Visible Spectroscopy (UV-VIS) UV-VIS spectroscopy, like FTIR, is a technique which is useful in the identification of pure drug compounds. Many molecules contain chromophores which will absorb specific wavelengths of ultra violet or visible light.
How does ultraviolet radiation affect polymers?
Some familiar examples of UV-induced polymer degradation are the yellowing and “chalking” of PVC pipes installed outdoors, the fading of colors in signage and posters that are exposed to the sun, the chalking and embrittlement in the insulation of wires that are exposed to sunlight or in a UV-C system, and, of course,
