Functional surfaces through the creation of adhesion and charged patterns on azopolymer surface relief gratings
We show that an azopolymer can be used to create a supramolecular architecture in a parallel process with patterned surface properties. By illuminating with an interference pattern, we created adhesion and charge patterns that reflect the molecular ordering. We studied the recording process in two l...
