Polycarbonate (PC) is one of the most widely used engineering thermoplastic owing to excellent physical and chemical properties. However

environment factors such as light

oxygen

temperature and humidity result in changes of the performance of polycarbonate. In order to improve performance of anti-aging of polycarbonate materials

it must be completely understood the mechanism of the aging process

and then purposefully modified. Three polycarbonate material aging reaction mechanism of physical aging

light oxygen aging and thermal oxygen aging are analyzed in this paper. At the same time

the structure and properties of polycarbonate changes caused by aging changes are introduced. Finally the paper also reviews the new progress of polycarbonate aging behavior research in recent years and a new interpretation of classical theory

puts forward future research direction at the same time.
