The aim of the research was corona discharge treatment of meta—(mAr) and para—(pAr) aramid fabrics to increase the surface free energy (SFE) and its polar component, without deterioration of the thermal properties. The fabrics were activated by plasma with 41.0, 71.75, and 102.5 J/cm2 energy. The SFE increased from 40.38 to 70.82 mJ/m2 for mAr and from 44.06 to 70.01 mJ/m2 for the pAr fabric, the...
New trends toward green technologies and broad utilization of polymers have led to intense research on surfaces with controlled wettability. This study demonstrates an easy method to control the wettability (estimated by static water contact angle [WCA]) of a polymer surface by introducing a proper ratio of C–F, C–H, and N–H bonds. The preparation method combines magnetron sputtering from a polytetrafluoroethylene...
