| Abstract: | The various plasmochemical technique for the surface functionalization and regulation of the biological characteristics of fluorocarbon polymers aimed at the enhance their blood compatibility are described. The plasmochemical treatment in oxygen and nitrogen containing gases has been used to increase of surface energy and hydrophoby of fluorocarbon polymers. Modification of the surface morphology and chemical structure to improve thromboresistive properties of polymers by plasma etching and deposition of biocompatible materials was demonstrated and discussed. Plasma-assisted immobilization of proteins in combination with other plasma modification methods provides a promising technique for engineering of a new generation of hemocompatible materials. |
