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... | Find, read and cite all the research you need on Tech Science Press
Highlights
Cellulose (C6H10O5)n is a linear natural biocomposite and an organic compound comprised of a glucose unit linked by β(1,4)-glycosidic
The bacterial cellulose (BC) was produced by Acetobacter xylinum Thailand Institute of Scientific and Technological Research (TISTR) 086 by consuming sugar or carbohydrates from oil palm shoot juice as their main food
After BC was treated with polyethylene glycol (PEG), PEG slowly penetrated into the BC networks and when the surrounding water of polyglucosan chains was substituted with PEG, it led to the formation of bonds between hydroxyl groups of BC and PEG
Summary
Cellulose (C6H10O5)n is a linear natural biocomposite and an organic compound comprised of a glucose unit linked by β(1,4)-glycosidic. It is isolated from vascular plants [1]. PEG is inexpensive and significantly less hazardous than other organic solvents [11] In addition it has hydrophilicity and thermal stability in the membranes [12]. 2.3 Preparation Biocomposite of BC/PEG (Mw 600, 1000 and 2000 g/mol) The wet BC pellicle was expelled to remove some of the free water. Distilled water was responsible for cleansing the surface of biocomposite BC so as to eliminate excessive PEG.
