  • Patent number: 9624385
    Abstract: The purpose of the present invention is to provide a copolymer allowing for an antifouling coating composition used for the formation of an environment-friendly antifouling coating film. The antifouling coating composition gives the coating film increased water resistance and can maintain the stable dissolution property and antifouling performance of the coating film without causing coating film defects such as a crack during long-term seawater treatment. An aspect of the present invention provides a copolymer for an antifouling coating composition, including a copolymer (A) having, on a side chain, a group represented by chemical formula (1) and having, on terminal, at least one of a group represented by chemical formula (2) and a group represented by chemical formula (3).

  • Patent number: 9617434
    Abstract: This invention relates to amphiphilic hydrogel particles for antifouling paint, which are environmentally friendly and in which anti-corrosion and antifouling effects can be maximized through a single coating process. The amphiphilic hydrogel particles are fabricated by encapsulating conducting polymer particles having anti-corrosion functionality with functional nanoparticles having antifouling functionality and then immobilizing the functional nanoparticles on a hydrogel matrix, whereby the conducting polymer particles contained in the functional nanoparticles are slowly and continuously released or the release rate thereof can be controlled so as to release the corresponding particles in a specific environment, ultimately maintaining long-term functionality. The conducting polymer particles contained in the amphiphilic functional nanoparticles can exhibit anti-corrosion functionality, thus maximizing anti-corrosion and antifouling effects through a single coating process.

  • Patent number: 9486560
    Abstract: Biodegradable polymer-coated surgical meshes formed into pouches are described for use with cardiac rhythm management devices (CRMs) and other implantable medical devices. Such meshes are formed into a receptacle, e.g., a pouch or other covering, capable of encasing, surrounding and/or holding the cardiac rhythm management device or other implantable medical device for the purpose of securing it in position, inhibiting or reducing bacterial growth, providing pain relief and/or inhibiting scarring or fibrosis on or around the CRM or other implantable medical device. Preferred embodiments include surgical mesh pouches coated with one or more biodegradable polymers that can act as a stiffening agent by coating the filaments or fibers of the mesh to temporarily immobilize the contact points of those filaments or fibers and/or by increasing the stiffness of the mesh by at least 1.1 times its original stiffness.
