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 (PTFE) target and plasma‐enhanced chemical vapor deposition (PECVD) from a nitrogen/acetylene mixture, making it environment‐friendly, unlike PECVD from hydrocarbons/fluorocarbons. The proposed method allows depositing plasma polymers with WCAs from 110° to 17° by varying only the gas composition. The corresponding plasma polymers consist of C:F (magnetron sputtering of PTFE), C:F:N:H (reactive magnetron sputtering and PECVD), and a‐C:H (PECVD from acetylene).

由C–F，C–H和N–H制成的等离子聚合物的量身定制的润湿性

绿色技术的新趋势和聚合物的广泛使用已导致对可湿性得到控制的表面进行了深入研究。这项研究表明，通过引入适当比例的C–F，C–H和N–H键，可以控制聚合物表面的润湿性（通过静态水接触角[WCA]估算）的简便方法。该制备方法将聚四氟乙烯（PTFE）靶材的磁控管溅射与氮气/乙炔混合物的等离子体增强化学气相沉积（PECVD）结合在一起，使其与环境友好，这与碳氢化合物/碳氟化合物的PECVD不同。所提出的方法允许通过仅改变气体组成来沉积具有110°至17°的WCA的等离子体聚合物。相应的等离子聚合物由C：F（PTFE的磁控溅射），C：F：N：H（反应磁控溅射和PECVD）和a-C组成：
