Core Application Areas and Technical Value

　　1. Semiconductor and Microelectronic Materials

　　ArF Photoresist Matrix Resin: When compounded with α-butyrolactone methacrylate (GBLMA) and 3-hydroxy-1-adamantyl acrylate (HADA), it can prepare photoresists with a resolution of 70 nm. Its adamantane structure regulates the dissolution rate through acid-catalyzed deprotection reactions, achieving a development contrast of 4.2 after 193 nm laser exposure, meeting the requirements of 14 nm advanced processes.

　　Low Dielectric Constant Packaging Materials: Copolymerized with fluoroacrylate, it can prepare packaging resins with a dielectric constant (ε) as low as 2.8, used for 5G chip interconnect layers, reducing signal transmission loss (30% lower than traditional epoxy packaging materials).

　　2. Optical and Display Materials

　　High Transparency Heat-Resistant Resin: The homopolymer has a light transmittance of 92% (400-800 nm) and haze < 0.5%, usable for LED packaging lenses, with no yellowing after long-term use at 150℃ (Yellowing Index YI < 1).

　　VR Device Optical Films: Blended with polycarbonate (PC), it can improve the scratch resistance hardness (pencil hardness 4H) and flexibility (no cracks after 180° bending 1000 times) of the film material, suitable for Fresnel lenses in VR headsets.

　　3. High-Performance Coatings and Adhesives

　　High-Temperature Anti-Corrosion Coatings: Copolymerized with silicone acrylate, the resulting coating maintains adhesion at 250℃ (cross-cut test grade 0) and salt spray resistance reaches 1000 hours (ASTM B117 standard), used for anti-corrosion of engine exhaust pipes.

　　UV-Curable Structural Adhesive: Adding 10-15% AdA can increase the shear strength of the adhesive layer to 28 mPa (aluminum substrate), while maintaining temperature cycle stability from -50℃ to 180℃, used for bonding aerospace components.

　　4. Biomedical Materials

　　Degradable Hydrogels: Copolymerized with polyethylene glycol diacrylate (PEGDA), it constructs pH-responsive hydrogels (swelling rate increases by 200% at pH < 5), used for drug targeted release systems in tumor microenvironments (weakly acidic).

　　Tissue Engineering Scaffolds: Forming porous scaffolds through double-bond polymerization, the hydrophobicity of adamantane groups can regulate cell adhesion behavior (cell viability > 90%), suitable for cartilage tissue repair.
