4-Biphenylmethanol acrylate

Core Application Areas and Typical Scenarios

1. OCA Optically Clear Adhesive

High-end Display Lamination: As a key monomer for OCA optically clear adhesive, it can be combined with polyurethane acrylate to prepare a transparent adhesive with a refractive index of 1.56, used for interlayer lamination of OLED screens. Its light transmittance (92%) and haze (<1%) are superior to commercially available PMMA-based adhesives.

Impact Resistance: Adding 5-10% BPMA can increase the impact strength of the OCA adhesive layer to 50 J/m, solving the cracking problem of flexible screens during drop tests.

2. Photoresists and Microelectronic Materials

High-resolution Photoresist: Combined with adamantyl acrylate, it can prepare ArF photoresist with a resolution of 110 nm. Its acidolysis reaction rate regulation capability (contrast 3.5) meets the requirements of advanced processes.

Electronic Packaging Materials: Participating in the modification of epoxy resins can reduce the dielectric constant of packaging materials (ε≈3.0) and improve the high-frequency signal transmission efficiency of 5G base station chips (signal delay reduced by 15%).

3. High-performance Coatings and Adhesives

High-adhesion Coatings: Copolymerized with polyurethane acrylate, the resulting coating exhibits adhesion to metals (such as aluminum, copper) (cross-cut test grade 0) significantly better than ordinary acrylate coatings. Moreover, its salt spray resistance (500 hours without rust) is improved by 30%, making it suitable for anti-corrosion in marine engineering.

UV-curable Adhesives: Adding 5-15% BPMA can improve the flexibility of the adhesive layer (elongation at break reaches 150%) while maintaining high shear strength (>15 MPa), used for interlayer bonding of flexible electronic devices.

4. Biomedical Materials

Degradable Hydrogels: Copolymerized with polyethylene glycol diacrylate (PEGDA) to construct pH-responsive hydrogels (swelling rate increases by 200% when 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 the biphenyl group can regulate cell adhesion behavior (cell viability > 90%), suitable for cartilage tissue repair.
