Laser-enhanced adhesion and thin film formation

UV-laser irradiation of polymers leads to different types of surface modifications, including the formation of structures with sub-micrometer dimensions. These structures may influence the adhesion of surface coatings. In this paper we investigate the temperature dependence of the growth of branched dendritic structures. Growth rates in excess of 1 nm/s were measured near the glass transition temperature of poly(ethylene terephthalate). Periodic surface structures are investigated with respect to physical formation processes.
