Polymer Brush Patterns

Surface-initiated synthesis Chemically modified substrate surface Eliminates the need for expensive photolithographic tools

详细技术说明

Researchers at the University of California, Davis have developed a novel method for the preparation of patterned polymer brushes. The formation of a patterned surface is achieved by using a microcontact printing technique followed by surface-initiated synthesis of polymer brushes within the framework of the pattern. In contrast to the production of complex patterns in polymer films on surfaces that combine spin-casting and photolithographic techniques, polymer films patterned by microcontact printing and surface-initiated synthesis are not limited by the stability of spin-coated films to solvents and chemical reaction, and difficulties in preparing uniform films over large areas and complicated topographies.
