As global worries about plastic pollution grow, biodegradable plastics are increasingly seen as a solution for a more sustainable environment. Cellulose fiber (CNF), derived from sources such as wood, starch, and bacteria, are emerging as frontrunners, attributed to their inherent biodegradability and commendable mechanical properties. This research delves into the formulation of polyolefin elastomers, specifically PE and PP compounds, fortified with 40wt% CNF. We elucidate the ramifications of CNF dispersion on the Young's modulus and tensile stress of POE, emphasizing the emergence of micro-aggregates or intricate networks within the polymer composites. The dispersion dynamics and aggregation tendencies of CNF, contingent on its content, were scrutinized through SEM/EDS images. Insights from this investigation hold potential for developing rubber-based materials with enhanced mechanical robustness and biodegradability, thereby addressing conventional plastics' limitations.
