Abstract
Abstract The renewable discovery resulting from the synthesis of nanocomposites using nano fibrillated cellulose (NFC) as a nanofiller and poly (vinyl alcohol) (PVA) as a matrix with the addition of carboxymethyl cellulose (CMC) additives demonstrates good potential for food packaging applications. NFC was synthesized through a mechanical homogenization method from microfibrillated cellulose (MFC) and was effectively characterized by its physical properties, including density and particle size. Subsequently, PVA/CMC/NFC nanocomposites were created using a mechanical homogenization method with various CMC concentrations (0, 0.5, 1, and 2%) and a 90:10 ratio of PVA/CMC to NFC. The resulting nanocomposites were also characterized for their physical properties. It was found that adding CMC 2% increased the density of the solution. Then, these nanocomposites were used to apply as a coating paper. Micro photo characterization was carried out on the nanocomposite to examine the nanocomposite’s morphology on the paper and evaluate the nanocomposite’s performance as a coating paper. The results indicate that the nanocomposite has an uneven particle size distribution and demonstrates agglomeration with increased CMC concentration. This is due to hydrogen bonding interactions among PVA, CMC, and NFC, the adhesion properties to the paper, and the ratio between PVA, CMC, and NFC in solution.
