  • Patent number: 9732249
    Abstract: A novel material is provided herein which is suitable for use in a precursor of a polymer coating material that coats a polymer on a surface of a base material to provide the base material with surface modification and/or functionality assignment. A composite material characterized in that a compound having a polymerization initiation site containing a halogen group is incorporated in a crosslinked structure comprising a catechol derivative or a phenol derivative represented by the following formula (I). In the formula (I), R may be interrupted by an oxygen molecule and represents a hydrocarbon group with 2 to 20 carbons that has at least one double bond site, and A represents a hydrogen atom, a hydroxyl group, or an alkoxy group with 1 to 20 carbons.
    Type: Grant

  • Publication number: 20090092814
    Abstract: The present invention provides a method for manufacturing a polymer thin film having high strength, flexibility, accuracy, and a large surface area. A method for manufacturing a polymer thin film, comprising: providing a layer of thermally-crosslinkable resin composition on a support; cross-linking a thermoplastic resin in the layer of thermally-crosslinkable resin composition thus provided; and after the thermoplastic resin is cross-linked, separating the support from the layer of thermally-crosslinkable resin composition.

  • Publication number: 20090029137
    Abstract: A method for producing a polymer thin film, comprising providing a composition that contains a polymerizable compound having at least two (meth)acryl groups on a support to form a layer, chain-polymerizing the polymerizable compound, and separating the layer from the support. The produced polymer thin film has high strength, flexibility and accuracy.
