Abstract
The aim was to study the effect of incorporating cellulose nanofiber on biodegradation of poly(vinyl alcohol) nanocomposite in a controlled composting environment. The nanocomposite was prepared by freeze-drying and the effect of (5, 10, 20 and 30%) CNF loading on biodegradation properties nanocomposite in controlled composting was characterized. Biodegradation tests were carried out using the standard ASTM D6340-98 which specifies a method for determining the carbon dioxide evolution. The results indicated that the biodegradation of PVA was increased with the introduction of CNF into a polymer matrix. With the addition of 5, 10, 20 and 30% of cellulose nanofiber, rate of biodegradation of nanocomposite increased. Furthermore, loss mass measurements showed that the presence of CNF led to an increase of biodegradability of PVA-based materials. With the addition of 5, 10, 20 and 30% of cellulose nanofiber respectively, increase in the amount of loss mass of the nanocomposite was observed with 4.78, 5.23 and 6.72%.
