Laminate and Coating Composition - A simplified explanation of the abstract

This abstract first appeared for US patent application 18553630 titled 'Laminate and Coating Composition

The abstract describes a laminate with thermally stable hydrophilicity and a coating composition for such a laminate. The laminate includes a substrate, a first layer with a binder and inorganic nanoparticles, and a hydrophilic second layer with a binder containing a cured product of a binder precursor with a high amount of tri- or higher functional (meth)acrylate monomer, and inorganic nanoparticles with a (meth)acryloyl group.

  • The laminate exhibits thermally stable hydrophilicity.
  • The first layer contains a binder and inorganic nanoparticles.
  • The second layer is hydrophilic and is placed on top of the first layer.
  • The binder in the second layer contains a high amount of tri- or higher functional (meth)acrylate monomer.
  • The inorganic nanoparticles in the first layer have a (meth)acryloyl group.

Potential Applications: - Medical devices - Optical coatings - Anti-fogging surfaces - Water purification systems

Problems Solved: - Maintaining hydrophilicity under thermal conditions - Enhancing durability of coatings - Improving adhesion to substrates

Benefits: - Increased performance in various applications - Extended lifespan of coated surfaces - Enhanced functionality in humid environments

Commercial Applications: Title: "Thermally Stable Hydrophilic Laminate: Commercial Applications and Market Implications" This technology can be used in medical equipment, optical devices, and consumer goods to improve performance and durability in various conditions.

Questions about the technology: 1. How does the high amount of tri- or higher functional (meth)acrylate monomer contribute to the stability of hydrophilicity in the laminate? 2. What are the specific advantages of using inorganic nanoparticles with a (meth)acryloyl group in the first layer of the laminate?


Original Abstract Submitted

Provided is a laminate that may exhibit thermally stable hydrophilicity, and a coating composition that may be used for such a laminate. A laminate according to one embodiment of the present disclosure includes: a substrate; a first layer disposed on at least one surface of the substrate, the first layer including a binder and an inorganic nanoparticle; and a hydrophilic second layer disposed on the first layer, the binder containing a cured product of a binder precursor containing 30 mass % or greater of a tri- or higher functional (meth)acrylate monomer relative to a total amount of the binder, and the inorganic nanoparticle having a (meth)acryloyl group.
