One other strategy of degradation is photodegradation, which is when a molecular bond is broken by the absorption of photon radiation (i.e. light). Resulting from cellulose acetate carbonyl teams, the molecule In a natural way absorbs light-weight at 260 nm,[186] nevertheless it includes some impurities that may absorb light. These impurities are acknowledged to soak up gentle in the much UV light-weight region (< 280 nm).[187] The ambiance filters radiation from the sun and enables radiation of > three hundred nm only to get to the area. Hence, the first photodegradation of cellulose acetate is taken into account insignificant to the entire degradation approach, because cellulose acetate and its impurities soak up light-weight at shorter wavelengths. Research is focused on the secondary mechanisms of photodegradation of cellulose acetate that can help make up for some of the limitations of biodegradation.
