Abstract
Poly-tert-butyl methacrylate-co-methyl methacrylate thin film surfaces were patterned and subjected to surface treatment by UV radiation and NaOH exposure, in order to tailor hydrophilic/hydrophobic conditions. The polymer has potential applications as elements of advanced biosensors and other bio-active devices. The topographies and surface chemistries on the micro- and meso-scales of thin films have been characterized by scanning force microscopy operated in the normal contact imaging mode as well as the lateral force and force versus distance modes.
