Abstract
Plasticizer is and additive for plastic to improve its elasticity and flexibility. In this experiment the composites based on chitosan-starch were synthesized at different weight ratios (7/3; 8/2; 9/1; 10/0)by using 12.28 - 24.24% volume of glycerol as Plasticizer. This paper studies the influence of Plasticizer on mechanical and chemical properties of chitosan-strach plastic film. The films were observed on the aspect of mechanical characteristic (tensile strengh, elongation at break), and %swelling. The mechanical characteristic of the film were characterized by autograph and swelling test. The alternation of chemical structure was studied by FTIR. The result showed the higher of chitosan-starch ratio increased the tensile strengh and the elasticity of film but decreased in %. Otherwise, the addiction of Plasticizer increased the elasticity of film and % swelling. These results suggested that these two film forming components were an interaction existed, a greater intensity was observed and the amino group bang of chitosan molecule in the FTIR spectrum shifted from 16o1 cm-1 in chitosan to 1590 cm-1 in composite films
