STUDY ON EXTRACTION OF CORN STRAW AND CORN CELLULOSE AND THE DEGRADATION PERFORMANCE OF REGENERATED FILM
In this paper,corn straw and corn cob are sifted into outer layer and inner layer,respectively.Then,the cellulose was separated by acid and alkali method,dissolved in ionic liquid AmimCl,cellulose film was regenerated in water from the solution of cellulose/AmimCl.At last,the cellulose content,degree of polymerization(DP)and the degradation were studied.This study provides a chance to prepare Functional cellulose Regenerated film using relatively cheap and large amount of corn byproduct as cellulose resources.The result showed that the content of cellulose in the outer layer of corn straw is higher than the inner layer.The cellulose content in the outer layer of corn cob is higher than that in the inner layer of corn cob; The Dp of corn straw cellulose is the highest among corn straw cellulose,corn cob cellulose and corn leaf; Corn straw regenerated film can be degraded in the soil and completely degraded in just 15 days.
