Quick Cite

Paragraph starter

Research indicates that the adhesion between natural fibers and polymer matrices is a critical factor in composite performance. For instance, studies on flax fibers have shown that their inherent hydrophobicity, due to substances like cutins, hinders effective bonding. Oxidative chemical treatments, which remove these hydrophobic components and increase cellulose content, have been demonstrated to significantly enhance fiber wettability and, consequently, interfacial adhesion. This leads to demonstrably improved physical and mechanical properties in the resulting composite materials, suggesting that surface modification is a key strategy for optimizing natural fiber composites.
