Modifying the Properties of Polypropylene-Wood Composite by Natural Polymers and Eggshell Nano-particles.

In this research, physical, thermal and mechanical properties of polypropylene composites modified with natural polymers such as starch and corn are studied. Also, the effect of adding eggshell nano-particles as fillers is investigated. 4 weight percentage of maleic anhydride as a compatibilizer of polypropylene was used in order to improve mechanical properties. Polypropylene-wood composites have been introduced as new sources of raw materials in various industries and have found their way through many applications such as automotive, building and furniture's industries. This polymer by itself or in combination with various resistant has good heat resistance, great flexibility at low temperatures and resistance against oxidation and ultraviolet radiation In the current research, bending and tensile tests were utilized for physical and mechanical examinations and also in order to evaluate surface morphology, SEM test was used. Results show that adding maleic anhydride and eggshell nanoparticles instigates improvement in mechanical properties as well as better adhesion between polymer, starch and corn particles.
