Abstract :
We prepare polylactide- cellulose (PLA-cellulose) by microwave irradiation method with lignocellulose as raw material and characterized by infrared spectroscopy (IR) and X-ray 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.
