Another strategy of degradation is photodegradation, which is when a molecular bond is damaged with the absorption of photon radiation (i.e. light). Due to cellulose acetate carbonyl teams, the molecule Obviously absorbs light-weight at 260 nm,[186] nevertheless it includes some impurities which could soak up light-weight. These impurities are identified to absorb light-weight while in the far UV light-weight region (< 280 nm).[187] The environment filters radiation in the sun and lets radiation of > three hundred nm only to reach the area. As a result, the primary photodegradation of cellulose acetate is considered insignificant to the full degradation process, because cellulose acetate and its impurities take up light at shorter wavelengths. Study is centered on the secondary mechanisms of photodegradation of cellulose acetate to aid make up for many of the restrictions of biodegradation.
