Question

What is photo degradation what are its effect

Answer 1

Answer:

Photodegradation is degradation of a photodegradable molecule caused by the absorption of photons, particularly those wavelengths found in sunlight, such as infrared radiation, visible light, and ultraviolet light.

However, other forms of electromagnetic radiation can cause photodegradation.

Answer 2

Photodegradation causes chain scission in the polymer material which results in the loss of important physical properties such as impact strength, tensile strength, elongation at break, etc. and can be observed as cracking, chalking and color changes.
