Ultra-Violet Excimer Laser Micro-Patterning of Polymers

Abstract Two polymer materials, PDLA and PVA, have been patterned by ultra-violet (UV) Excimer laser micromachining for biomedical applications. In this work, Parametric investigations were conducted for both PVA and PDLA polymers using a XeCl (Xenon-chloride) Excimer laser of 308 nm wavelength. Laser machined micro-patterns were examined by a high-resolution optical microscope. A surface profilometer was used to measure the …
