ABSTRAK

Biodegradable biocomposites films made from a mixture of poly L- lactide acid PLLA and MCC microcrystalline cellulose with a weight ratio of MCC 02.557.5 and 10 by using solvent blending techniques. The aim of this study is to investigate the effect of MCC addition on the transparency dispersion thermal stability and mechanical properties of biocomposite products. The transparency of biocomposite films decrease with the addition of MCC filler dispersed in the PLLA matrix. The SEM results show that the more filler addition the more PLLA matrices that are filled by filler. Thermogravimetric analysis showe that the addition of MCC increase in thermal stability of biocomposites film. Most stable biocomposite film is reached by the composite with MCC content of 5 wt with Tonset 30935oC. Mechanical tests on biocomposite test include tensile strength and elongation at break. The value of tensile strength of biocomposite films decrease with the increasing MCC content the highest value of tensile strength is 39 Mpa which is for neat PLLA. The elongation at break in the biocomposite films decrease with the addition of MCC the highest value of elongation at break is 11 which is for neat PLLA.
