  • Method for surface engineering
    Patent number: 6706320
    Abstract: A process for modifying the surface of a substrate containing a polymeric material by contacting the surface with the modifying agent to bond the modifying agent to the surface the process comprising providing a solution of the modifying agent in a solvent and subjecting the solution of the modifying agent to a zone of elevated temperature to vaporize the solvent and provide diffuse contact between the modifying agent and the surface of the substrate.
    Type: Grant
    Filed: February 12, 2001
    Date of Patent: March 16, 2004
