This study investigates the controlled modifications of surface wettability of cyclic olefin polymer (COP) by the use of femtosecond laser pulses at various fluences by changing the defocusing distance. A wide range of water contact angles (WCA) were achieved, surfaces ranged from highly hydrophilic...
