A comprehensive review on modified phenolic resin composites for enhanced performance across various applications

Abstract Phenolic resin (PR), renowned for its strong adhesive properties, superior heat resistance, and excellent chemical stability, finds extensive applications in industries, such as electronics, coatings, and textiles. However, with the advancement of technology, the need to modify PR to meet higher standards in specialized fields has become a significant research focus. Current research on PR modification emphasizes both physical methods, including filler enhancement and fiber reinforcement, and chemical methods, such as copolymerization, grafting, and cross‐linking. This review provides an in‐depth examination of the progress in PR modification research from both physical and chemical perspectives, highlighting the improved performance post‐modification. Additionally, we summarize the latest advancements in the application of PR composites and predict future trends and growth prospects. This review aims to guide the design and implementation of modified PR composites for enhanced performance across various domains. Highlights Physical/chemical modifications enhance PR composites for high‐end use. Advancements in PR composites guide future material design trends. Modifications improve mechanical, thermal and corrosion resistance properties.
