Preparation and Characterization of Regenerated Nanocomposite Made from Bacterial Cellulose/PMMA

摘要

Bacterial cellulose (BC)/Polymethylmethacrylate (PMMA) nanocomposite was prepared by immersing regenerated BC membrane (RBC) in PMMA aqueous solution followed by oven-drying process. The regenerated membrane was obtained through a simple approach by phase inversion method using bacterial cellulose and lithium chloride (LiCl)/dimethylacetamide (DMAc) as solvent. The structure of the membrane was investigated by the scanning electron microscopy (SEM). It shows very smooth, dense and homogeneous surface but owing layer structure. Tensile test results indicate that BC/PMMA nanocomposite has higher tensile strength compared with neat PMMA sheet. After dipping treatment, its light transmission could attaining 89.4%. Consequently, the obtained RBC/PMMA nanocomposite may be potentially used as the substrate of flexible Organic Light Emitting Diode (OLED) and packaging materials.
