Aging mechanism of wood-plastic composite was: light and heat break down the long molecular chains of wood flour and plastic; the free radicals reacted with the oxygen, which generated carbonyl groups, hydroperoxides and so on; the free radicals also had cross linking reaction, which generated alkoxy; Water destroyed the interface of wood flour and plastic, hydrolyzed ester additives, extracted the small molecule additives and degradation products; Microorganism degraded cellulose, semicellulose, lignin and ester additives; degradation product from different component accelerated the aging, which could be exampled by the fact that HCl from degradation of PVC accelerated the hydrolyzation of cellulose and semicellulose.

Treatment by different methods, samples in original state, free of wax, free of lignin and hemicellulose were obtained. Then, they were attached on the surface of new cleaved mica and measured by tapping mode AFM. It was found that the main structure of straw cell wall is composed of buddles of cellulose microfibrils, and hemicellulose links them together to form a network structure, on the surface of the network lignin aggregate together to form a protect level. The AFM result consistency very well to the theoretical model of cell wall proposed by Vincent.
