Modification of Polyethylene Terephthalate by Low-Temperature Plasma for Use in Medicine and Biology

摘要

An analysis of the literature on polyethylene terephthalate modification by low-temperature plasma treatment is presented. The use of modern instrumental methods (measurement of contact angles and calculations of surface energy and its components, X-ray photoelectron spectroscopy and FTIR spectroscopy, atomic force and scanning electron microscopy) for studying the properties of processed polymer samples is considered. The change in contact properties, chemical structure, and morphology of the modified surface of polyethylene terephthalate is shown. Data on studying hemocompatibility, antibacterial activity, and cell adhesion and proliferation after plasma treatment of polyethylene terephthalate are presented.
