Ultra-short laser-based sustainable structuring of polypropylene surfaces for frequently touched superficies

Abstract In this study, the influence of femtosecond and picosecond laser processing parameters on the surface morphology and wettability properties of polypropylene for future application in the design of persistent bacteria-free frequently touched surfaces was investigated. It is identified that the morphology and wettability of laser-induced surface structures created can be efficiently tuned by adapting the laser processing parameters to create structures, which could possess antibacterial properties.
