Non-biodegradable property of plastic materials become a serious environmental problem as increase of plastic wastes. Therefore, cellulose fibers from wood, starch, and bacteria has received a huge attention due to their biodegradability, flexibility, and mechanical properties. In this work, we fabricated polyolefin elastomer, PE, PP compounds that contain 40 wt% of cellulose nanofiber (CNF). Dispersed CNF impacts on Young’s modulus and tensile stress of POE forming micro aggregation or networks in the polymer mixtures. The dispersion and aggregation of CNF was observed by SEM and EDS images by the contents of polymer and CNF. This study can be applied to rubbery materials that need high mechanical properties and biodegradability such as gasket of vehicles, shoe sole, and packaging overcoming the problems of ordinary plastics.
