This article with 29 references in details reviewed the degradation mechanism of cellulose material and the classification of bio degradation plastics prepared from natural high molecular cellulose material; stated the researching status and development of this kind of plastics out and in the country, and narrated the methods to research the degradation mechanism of this type of plastics.

Cellulose material is abundant in resource and has good reactivity, excellent degradable property and non-toxicity.

In our country, there are many project in the advance research has been proceeded, however, as the cellulose synthesis and the functional cellulose are late to investigate, at the same time, it seems to lack in ability for the cellulose structure research.

Catalytic cracking oil slurry after filtration separation can be used to manufacture carbon black,needle coke,carbon fibrous material,plasticizer and so on.

At the same time,the theoretic ideas and technical route of wood carbon fibrous materials prepared by using wood-phenol liquefaction product were introduced on the base of wood liquefaction and nano-spinning technique,which will develop a new pathway for the preparation of wood-materials with n.
