Plastic waste is appearing as a serious threat to environment, because of its non-biodegradable property. Therefore, cellulose fibers from wood, starch, and bacteria attracted the attention of many research groups due to its biodegradability, flexibility, and mechanical properties to overcome the problems of ordinary plastics. In this work, we fabricated polyolefin elastomer (POE) compounds that contain 80phr of cellulose nanofiber (CNF). To disperse CNF into POE, we adopted two types of POE as a base resin and found optimal composition of them. Dispersed CNF improves Young’s modulus and tensile stress of POE forming micro aggregation in the POE mixtures. The dispersion and aggregation of CNF was observed by SEM and EDS images by the contents of POE 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. |
