Results of contact angle measurements for control polymer (n—number of measurements, n = 2) and EUV modified surfaces (n = 8). A significantly low wettability can be observed in three cases of: PVDF_50_O400 compared to PVDF_N200 and PVDF_50 (* p < 0.05); PTFE_50/PLLA_50_O400 compared to other PTFE/PLLA variants (& p < 0.05); PTFE_50_O400 compared to PTFE_control, PTFE_50, PTFE_50_N200, PTFE_50_N400 (# p < 0.05).
