Abstract
Date palm seeds (DPS), a plentiful agricultural waste in Arab countries, present a promising, sustainable, economical reinforcement polymer composite material. This review addresses critical gaps in understanding innovative procedures to improve the mechanical and sustainability properties of DPS-reinforced polymer composites. While the promise of DPS is highlighted by recent research, it frequently lacks a comprehensive analysis of the long-term durability, optimum processing conditions, and environmental influence.
In this review, the influence of filler loading, particle size, nanomaterial additions, treatment conditions, and polymer matrix selection on composite mechanical properties is investigated particular attention is given to innovative strategies containing Ultrasonic-assisted alkaline pretreatment followed by silane coupling agents addition, this technique enhances composite adhesion by combining a chemical modification and a more effective alkaline treatment, which leads to significant enhancements in tensile strength and biodegradability. Furthermore, the mechanical characterization and potential applications of these materials were investigated, including automotive, construction, packaging, and biomedical industries, and strategies for optimizing recycling processes to minimize environmental impact. By uniting recent advancements and recognizing main knowledge gaps, this review will provide a pathway for future research focused on maximizing the efficient utilization of DPS in advanced polymer composites, thus contributing to eliminating reliance on synthetic fibers and endorsing a circular economy.
