Honeycomb-like pattern formation on perfluoroethylenepropylene enhanced by plasma treatment

The presented paper is aimed on the plasma activation of perfluoroethylenepropylene for construction of honeycomb-like structures on its surface by dip-coating technique complemented with phase separation of biopolymer poly-l-lactid acid. Surface activation with plasma significantly improved the possibility of successful HCL pattern formation on perfluoroethylenepropylene polymer compared with pristine foil. The idea of surface pretreatment with plasma allowed us to prepare also pattern with different pore dimension, which may have a significant role for cytocompatibility enhancement and growth of specific cells such as osteoblasts. The unique combination of plasma treatment and dip-coating technique as simple and cheap procedure was confirmed to be a significant tool for honeycomb-like structure construction.
