A new biocomposite was preformed between bacterial cellulose(BC)pellicle and polyethylene glycol(PEG)at different concentrations(0%,5,10%,15%and 20%)and different molecular weight(600,1000 and 2000).The structure and ...A new biocomposite was preformed between bacterial cellulose(BC)pellicle and polyethylene glycol(PEG)at different concentrations(0%,5,10%,15%and 20%)and different molecular weight(600,1000 and 2000).The structure and mechanical properties of BC/PEG biocomposite were investigated.The results indicated that the properties of the BC were improved by the addition of PEG.The morphology of the BC and BC/PEG blend was examined by a scanning electron microscope(SEM).These showed that PEG was coated with a large pore size fibril on the BC and the BC/PEG was dense with an even and smooth surface.All the Fourier transform infrared spectroscopy(FT-IR)thermograms of BC/PEG showed the same functional groups as typical BC and PEG.The DSC result showed that the thermal stability improved which might be associated with a weak interaction between BC and PEG,and may be useful for applications.展开更多
