In modern materials science, epoxy resins are widely utilized across various fields due to their excellent mechanical properties, chemical stability, and electrical insulation characteristics. unmodified epoxy resins often exhibit limitations such as brittleness and poor heat resistance. To address these challenges, modification techniques for alicyclic epoxy resins have emerged. By incorporating alicyclic compounds, the performance of epoxy resins is enhanced to better adapt to complex and variable application environments. This paper reviews the recent advances in the modification of alicyclic epoxy resins.

Alicyclic compounds, owing to their unique molecular structures and physicochemical properties, significantly improve the heat resistance, chemical resistance, and mechanical properties of epoxy resins. For instance, the cyclic structure of alicyclic epoxy compounds provides higher thermal stability, enabling modified epoxy resins to maintain performance at elevated temperatures. Additionally, the presence of alicyclic groups enhances chemical stability, ensuring structural integrity under harsh conditions.

Modification methods for alicyclic epoxy resins are diverse, primarily categorized into chemical modification, physical modification, and functionalization modification:

Chemical modification involves incorporating alicyclic compounds into the epoxy resin molecular chain via chemical reactions to alter its structure.
Physical modification combines alicyclic compounds with epoxy resins through physical processes such as melting or solution treatment to form composites.
Functionalization modification introduces functional groups during modification to impart new properties, such as conductivity or magnetism.

Research progress in alicyclic epoxy resin modification focuses on the following aspects:

Development of Novel Alicyclic Compounds: Recent studies have synthesized new alicyclic epoxy compounds with higher thermal stability and lower melting points. For example, researchers at the Institute of Chemistry, Chinese Academy of Sciences, have developed a series of compounds that expand options for epoxy resin modification.
Optimization of Modification Processes: Researchers have refined modification techniques by adjusting reaction conditions, controlling reaction times, and selecting appropriate solvents to improve efficiency and reduce costs.
Application Studies of Modified Epoxy Resins: Modified alicyclic epoxy resins demonstrate promising potential in fields such as electronic packaging, aerospace, and automotive manufacturing. For example, they exhibit superior adhesion and reliability in electronics and enhanced high-temperature and radiation resistance in aerospace applications.
Environmentally Friendly Modifiers: With growing environmental awareness, the development of biodegradable alicyclic compounds for epoxy modification has become a research focus to minimize ecological impact.

The modification of alicyclic epoxy resins represents a cutting-edge research direction in materials science. As new compounds and optimized processes continue to emerge, coupled with in-depth application studies, this technology is poised to drive significant advancements in materials science.
