Preparation and Characterization of Nanocellulose-PVA Membranes from Peanut Shells Using Electrospinning

Abstract

The membrane structure design is critical to the development of high-performance hemodialysis membranes applications and many others in various fields. In this study, bifunctional thin-film Nano fibrous composite membrane was synthesized, consisting of cellulose nanocrystalline (CNC) and poly vinyl alcohol (PVA) hydrogel as a separation layer. CNC was prepared from agriculture waste by 30% hydrolysis followed by sonication. The structural characteristics revealed the nanoscale structure. They showed two diffraction peaks at 15.2209° and 22.5071° indicating typical type I cellulose crystalline planes, transforming cellulose to nano cellulose crystalline structure. Electrospinning was used for prepare nanofibrous membranes from CNC reinforced with PVA to produce nanofiltration membranes. Membranes with ratios 8:2, 7:3 and 5:5 were successfully prepared with the 5:5 CNC:PVA membrane having a fiber network average width of 48.67nm.
