ADHESIVE FILM, ELECTRONIC DEVICE INCLUDING THE SAME, AND VEHICLE INCLUDING THE ELECTRONIC DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240318046 titled 'ADHESIVE FILM, ELECTRONIC DEVICE INCLUDING THE SAME, AND VEHICLE INCLUDING THE ELECTRONIC DEVICE
The patent application describes an adhesive film created by curing a composition containing a high-molecular-weight acrylic polymer, a low-molecular-weight acrylic polymer, a cross-linking agent, a photoinitiator, and a molecular weight regulator.
- The high-molecular-weight acrylic polymer has a weight average molecular weight of 700,000 or more.
- The low-molecular-weight acrylic polymer has a weight average molecular weight of less than 500,000.
- The adhesive film has a degree of stress relaxation and creep properties within specific ranges.
- The film also exhibits a modulus at 25°C ranging from 0.04 MPa to 0.70 MPa.
Potential Applications: - This adhesive film could be used in the manufacturing of various products requiring strong adhesion properties. - It may find applications in industries such as automotive, electronics, and construction.
Problems Solved: - Provides a solution for creating adhesive films with specific mechanical properties. - Offers a formulation that balances high and low molecular weight acrylic polymers for optimal performance.
Benefits: - Enhanced adhesion and mechanical properties. - Improved stress relaxation and creep resistance. - Versatile applications across different industries.
Commercial Applications: Title: Innovative Adhesive Film Technology for Enhanced Product Performance This technology could be commercialized for use in the production of automotive parts, electronic devices, and construction materials, among other applications.
