Preparation of cellulose copolymer grafted polylactide(PLA) by the microwave method

Abstract

We prepare polylactide-cellulose (PLA -cellulose) by microwave irradiation method with lignocellulose as raw material and characterized by infrared spectroscopy (IR) and Xray diffraction. The results show that polylactide can be graft on to the cellulose surface by microwave irradiation method. The grafting rate can be achieved nearly 350% when the proportion of the amount of cellulose and lactide from 10-90wt%. The cellulose-based copolymer has hydrophobic segments and can be used to release hydrophobic drugs.
