Mechanical and Biodegradable Properties of Nano Multicomponent

A novel multicomponent nanobiodegradable composite consisted corn starch, high density polyethylene (HDPE), linear low density polyethylene (LLDPE) and nanoclay cloisite 30B were prepared by melt mixing. Polyethylene grafted maleicanhydride (PE-g-MA) was used as a compatibilizer in this composites. The results showed that in addition 3% wt of nano clay in the composites, a good dispersion of the nano particles and a combination of intercalated and nearly exfoliatedstructure was obtained in the sample by microstructure study of X-ray diffraction. Mechanical properties of the bio composites showed that the tensile strength, Young’s modulus and elongation at break increase when a cloisite 30B was used as a reinforcement. Biodegradation studied in activated sludge samples were tested by weight loss methods and scanning electron microscope (SEM) observed holes and cracks on the surfaces can be considered as signs of the samples biodegradation
