Carboxymethyl Cellulose

Plastik Biodegradable adalah bahan plastik yang dibuat dari bahan berbasis bio (alam) seperti pati, kitosan, rumput laut, asam poli laktat, protein dan sebagainya. Pati merupakan simpanan karbohidrat dalam tumbuh-tumbuhan dan merupakan  karbohidrat  utama  yang  dimakan  manusia di seluruh dunia. Dari hasil analisa pengaruh konsentrasi sorbitol degan carboxymethyl cellulose pada pembuatan plastik dari ampas tebu dan pati ampas tahu dapat di simpulkan bahwa dapat digunakan sebagai bahan pengental, pembentuk gel, perekat, dan ikatan pada bioplastik. Pengaruh konsentrasi sorbitol sebagai plasticizer untuk mengurangi kerapuhan, meningkatkan fleksibilitas dan ketahanan. Pengaruh konsentrasi carboxymethyl cellulose dan sorbitol dapat memperlambat degradasi plastik di dalam tanah dan membutuhkan waktu yang cukup lama.

Layer Assembly

The application of an oppositely charged dual polymer system is a promising approach to enhance paper strength. In this work, modified chitosan (MCN), a cationic polymer, and carboxymethyl cellulose (CMC), an anionic polymer, were used sequentially to improve paper strength. The adsorption of MCN on cellulose fibers was analyzed via polyelectrolyte titration. The formation of MCN/CMC complex in water and the deposition of this complex on silicon wafers were investigated by means of atomic force microscope and quasi-elastic light scattering techniques. The results showed that paper strength was enhanced slightly with a layer-by-layer assembly of the polymers. However, if the washing stage, which was required for layer-by-layer assembly, was eliminated, the MCN/CMC complex was deposited on fibers more efficiently, and the paper strength was improved more significantly. The significant improvement was attributed to the extra development of fiber bonding, confirmed further by scanning electron microscope observation of the bonding area of fibers treated with or without washing. However, the brightness of papers was somewhat decreased by the deposition of the complex on fibers. Higher paper strength also was achieved using rapid drying rather than air drying.
