本文报道了大气压微等离子体射流对聚苯乙烯（PS）的空间分辨表面改性。使用接触角、XPS、AFM和透镜上皮细胞（LEC）生长研究了使用直径为100 µm的微等离子体射流处理PS表面。微等离子体射流处理在直径为1.5 mm或更大的圆形图案中产生约60°的接触角的限定减小。空间分辨XPS分析表明，接触角的减小与O1s峰强度的增加有关。原子力显微镜证实，微等离子体射流处理不会导致表面粗糙度的显着变化。LEC局限于治疗区域。
This paper reports the spatially resolved surface modification of polystyrene (PS) using an atmospheric‐pressure microplasma jet. Treatment of PS surfaces using a microplasma jet with a 100 µm diameter is investigated using contact angle, XPS, AFM and lens epithelial cell (LEC) growth. Microplasma jet treatment creates a defined reduction in contact angle of approximately 60° in a circular pattern with a diameter of 1.5 mm or more. Spatially resolved XPS analysis demonstrates that a reduction in contact angle is related to an increase in O1s peak intensity. AFM confirms that microplasma jet treatment causes no significant change in surface roughness. LECs are confined to a treated area.
