Abstract

In the present paper, cold plasma-activated and chitosan-coated polyetheretherketone (PEEK) was covered with thin films of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine, cholesterol, cyclosporine A, and their mixtures using the Langmuir-Blodgett technique. The thermodynamic function, i.e., surface free energy, of those systems was determined based on the contact angle hysteresis (CAH) approach. This parameter seems to be essential in determination of cell adhesion to polymeric materials and molecular interactions with living tissues. The obtained results show that the wettability and surface free energy of PEEK can be changed depending on the composition of the coating.

壳聚糖修饰和脂质/多肽修饰PEEK表面的润湿性

本文采用Langmuir-Blodgett技术，用1,2-二棕榈酰-sn-甘油-3-磷酸胆碱、胆固醇、环孢菌素A及其混合物的薄膜覆盖了冷等离子体活化和壳聚糖包覆的聚醚醚酮（PEEK）。基于接触角滞后（CAH）方法确定了这些系统的热力学函数，即表面自由能。这个参数似乎在确定细胞对聚合物材料的粘附以及分子与活体组织的相互作用中是必不可少的。结果表明，PEEK的润湿性和表面自由能随涂层成分的不同而变化。
