Abstract:

Plastic waste cause a problem for environmental conservation, plastic materials are resistance against degradation by microorganisms so remain in the environment for many years. Biodegradable polymer could solve this problem. In this article, biodegradability of Linear Low Density Polyethylene (LLDPE) with chitosan was studied. Polyethylene grafted maleic anhydride (PE-g-MA) used as a compatibilizer. Samples with different levels of chitosans (as 3.7%, 7.4%, 10%, 15% and 20%) with constant amount of PE-g-MA were prepared. In all samples amount of compatibilizer are the same. The biodegradation of blends was studied with soil burial and exposure to mould growth. Biodegradation determined by weight lose, the change in mechanical properties of the sheets, mould growth and SEM test. The results showed that with increasing chitosan content biodegradability of blends increased. Biodegradation of the samples due to soil burial after 11 months revealed that the weight of the blends was decreased by increasing the chitosan level.
