Abstract

This study investigated the fiber dispersion characteristics and physical property changes of HwBKP-PP composites through repeated hydrophobization and recycling of cellulose fiber. The gas-grafted paper was disintegrated and then gas-grafted again to achieve uniform dispersion of the cellulose fibers with PP. With each gas grafting repetition, the interfacial affinity between the hydrophobized fibers and PP improved, leading to enhanced tensile strength and melt flow index of the HwBKP-PP composite material due to the improved fiber dispersibility. However, recycling of hydrophobic paper resulted in the loss of fines in the recycled paper, so that increase in average fiber length caused fiber agglomeration, resulting in poor dispersibility, and subsequently decreasing the tensile strength and melt flow index of the composite.
