Core Application Areas and Typical Scenarios

1. Semiconductor Photoresists

ArF Photoresist: As a matrix resin monomer, it is combined with γ-butyrolactone methacrylate (GBLMA) and 3-hydroxy-1-adamantyl acrylate (HADA) to prepare high-sensitivity photoresists with a resolution of 0.5 μm. Its adamantane structure regulates the dissolution rate through acidolysis, achieving a development contrast of 3.8 after exposure to 193 nm laser, meeting the requirements of advanced processes.

Negative Photoresist: After forming an inclusion complex with cyclodextrin, it can construct a supramolecular crosslinking network that maintains colloid softness even in a -30°C freezing environment. It is used for automatic labeling of refrigerated blood bags, solving the problem of traditional acrylate adhesives becoming brittle at low temperatures.

2. Optical Materials

High Refractive Index Coating: Combined with isosorbide diacrylate, it can prepare a transparent resin with a refractive index of 1.58, used for smartphone camera lenses. Its light transmittance (88%) and scratch resistance hardness (4H) are superior to commercially available PMMA materials.

UV-curing Lens: Adding 5-10% MAM to the UV curing system can improve the refractive index uniformity of the lens to Δn<±0.0005, suitable for micro-nano optical elements in AR/VR devices.

3. Biomedical Field

Drug Synthesis Intermediate: Used as a key raw material for synthesizing novel drugs with antibacterial, antiviral, and anticancer properties; its unique structural characteristics play an important role in the construction of drug molecules.

Biodegradable Materials: Combined with polylactic acid block polymers, it can prepare eco-friendly tapes that fully degrade within 30 minutes after getting wet, solving the application limitations of traditional acrylate adhesives in open-air operations.

4. Smart Responsive Materials

Thermosensitive Hydrogel: Copolymerized with N-isopropylacrylamide, it can construct a smart hydrogel with a Lower Critical Solution Temperature (LCST) of 32°C, used for drug sustained-release systems. Its swelling ratio (500%) and mechanical strength (264 kPa) are superior to ordinary PNIPAM gels.

Photoresponsive Polymer: By introducing MAM via radical polymerization, a photoresist that undergoes volume shrinkage (shrinkage rate 12%) under 365 nm light irradiation can be prepared, used for precision molding of Micro-Electro-Mechanical Systems (MEMS).
