Article Preview

The objective of this study was to reinforce biodegradable polyvinyl alcohol (PVA) with nano cellulose fibrils generated from poplar and cotton through mechanochemical treatment. A method used a combination of acid and alkali treatment to obtain cellulose from poplar and cotton. The cellulose of both fibers was further processed by grinder treatment. PVA/nano cellulose composite was prepared successfully by an immersion method. The cellulose nanofibers and nanocomposite films were characterized with scanning electron microscope (SEM), tensile testing machine, ultraviolet-visible spectrophotometry (UV-vis). SEM showed the diameter of the cellulose was range between 30-100 nm and exhibited a high aspect ratio of over 1500. The mechanical properties of PVA were improved significantly and the two plant nanofibers had the similarly reinforcing effects in the matrix. Cellulose nanofibers as a future resource have tremendous potential since they are one of the most abundant organic resources on the earth.
