I am using SU-8 to be a mold on glass substrate and then pour PDMS on the top of this mold to build up a microfludic device. After developing SU-8, the whole mold is stripped. The reason why I guess is that the interfacial area bewteen SU-8 and glass is pretty small, therefore the adhesion is not good. Is there any product that can enhance the adhesion between SU-8 and glass. Lunghao -- Dept.of Mechanical Engineering Univ. of Colorado Boulder
