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.
期刊介绍：
Progress in the Chemistry and Application of Chitin and its Derivatives is an annual journal focused on all aspects of production, modification, enzymology and application of chitin and its many derivatives, including chitosan. The journal publishes full-length papers as well as invited reviews. To be considered, papers must present original research that has not been published or accepted for publication elsewhere. The language of the journal will be English.
