Abstract

This study explores the impact of natural weathering on the mechanical, structural, morphological, and aesthetic properties of linear low-density polyethylene (LLDPE) composites reinforced with 15% palm petiole fibers (PPF) subjected to successive chemical treatments. Composites were exposed to Biskra, Algeria’s arid conditions for 360 days. FTIR analysis identified carbonyl peak formation, signifying oxidation, while weight loss measurements revealed enhanced biodegradability in treated composites, with weight loss proportional to exposure duration. SEM micrographs demonstrated pronounced surface deterioration in sodium hydroxide and hydrogen peroxide-treated composites compared to acetylated variants, which exhibited better resistance. Notably, UV-induced cross-linking in the polymer matrix and fiber recrystallization improved tensile strength and Young’s modulus. These findings highlight the potential of chemically treated PPF/LLDPE composites for sustainable applications in arid environments, balancing enhanced mechanical performance with biodegradability.

期刊介绍： Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
