Abstract

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.
