To address the toughness limitations of thermosets, researchers have explored various toughening strategies, including the incorporation of toughening agents such as rubbers, thermoplastics, and liquid crystal polymers, as well as the modification of monomer and resin network structures.

In the field of modern materials science, thermoplastic resins play an irreplaceable role due to their unique physical and chemical properties across numerous applications. with advancements in technology and societal development, the demands for material performance have become increasingly stringent. Traditional thermoplastic resins can no longer meet these escalating requirements, making the modification of thermoplastic resins to enhance their properties an urgent challenge to address.

The modification of thermoplastic resins involves improving their performance by adding, mixing, or altering their molecular structures. Such modifications not only enhance properties like heat resistance, chemical corrosion resistance, and mechanical strength but also expand their application range—from conventional plastics to high-performance composites, biomedical materials, and beyond.

Modification strategies for thermoplastic resins can be approached from multiple angles. First, adjusting the material composition by incorporating different fillers or reinforcing agents can improve mechanical properties. For example, adding glass fibers significantly boosts tensile strength and rigidity, while carbon fibers drastically increase tensile strength and modulus. Inorganic fillers such as talc powder or mica powder can reduce water absorption and coefficient of expansion, thereby improving dimensional stability.

Second, modifying the molecular structure through copolymerization or introducing functional monomers offers another route. For instance, copolymerization can incorporate functional groups (e.g., carboxyl or hydroxyl groups) into the resin, enabling chemical reactions with polymer chains to form cross-linked networks. This enhances heat resistance and mechanical strength.

Third, functionalization via grafting or copolymerization introduces specialized properties. Grafting techniques can integrate photosensitive groups for light-curable resins, while copolymerization can introduce antibacterial groups to impart antimicrobial properties.

Finally, processing techniques such as melt extrusion or injection molding allow modified resins to be fabricated into products tailored to specific applications.

In practice, modification schemes must align with specific needs. For high-temperature applications, heat-resistant fillers or copolymers with thermally stable groups are selected; for high-strength requirements, reinforcements like carbon fibers or high-modulus copolymers are used.

modifying thermoplastic resins is a multidimensional and layered process. By comprehensively optimizing composition, structure, and processing, their performance can be substantially improved to meet diverse demands. In the future, resin modification will undoubtedly play a pivotal role in advancing materials science and driving human progress.
