To satisfy high-end and demanding application requirements, phenolic resin modification always stays the research focus in this field. This review involved two main characteristics of phenolic resins, toughness and heat resistance.

In the field of modern material science, resins—as a critical class of polymer materials—have seen increasingly widespread application of modification technologies. Resin modification not only significantly enhances mechanical properties, thermal resistance, chemical corrosion resistance, and other physical and chemical characteristics but also plays a vital role in developing high-performance composite materials. This paper aims to explore in depth the functions and applications of resin modification, providing references for research and industrial practices in related fields.

1. Definition and Importance of Resin Modification

Resin modification refers to the process of adding or altering chemical components within the resin to obtain polymer materials with specific properties. Such modifications can strengthen mechanical properties, improve thermal stability, enhance chemical resistance, and better adapt the material to specialized application scenarios.

2. Main Methods of Resin Modification

Resin modification encompasses diverse approaches, including:

1. Blending Modification: Physically or chemically combining different resin types to form new composite materials. This approach effectively leverages the advantages of various resins while compensating for the limitations of single resins.
2. Graft Modification: Chemically grafting functional monomers onto resin molecular chains to impart new functional characteristics.
3. Filling Modification: Adding fillers (e.g., glass fiber, carbon fiber, diatomaceous earth) to enhance mechanical strength and thermal stability.
4. Surface Treatment Modification: Applying physical or chemical treatments (e.g., coating, electroplating, anodizing) to the resin surface to improve corrosion and wear resistance.
5. Radiation Modification: Using radiation (e.g., gamma rays, X-rays) or electron beams to alter the molecular structure and improve performance.

3. Functions of Resin Modification

1. Enhancing Mechanical Properties: Blending or filling modifications can substantially improve tensile strength, compressive strength, and impact toughness.
2. Improving Heat Resistance: Graft or radiation modification enables resins to maintain stability at higher temperatures.
3. Enhancing Chemical Resistance: Filling or surface treatment modifications boost acid, alkali, and solvent resistance.
4. Upgrading Electrical Insulation: Modified resins exhibit significantly enhanced electrical insulation properties, suitable for electronics and electrical equipment.
5. Expanding Application Fields: Modified resins enable the creation of composites with specialized functions, broadening their use in aerospace, automotive manufacturing, new energy, and other sectors.

Resin modification technology is a cornerstone of material science, optimizing and elevating resin performance through diverse methods. As technology advances and market demands evolve, resin modification will continue to develop and improve, contributing further to human progress.
