Nanostructuring of polymethylpentene by plasma and heat treatment for improved biocompatibility
Original language description
Abstract: This work is focused on the characterization of the surface properties of PMP (poly-4-methyl-1-pentene) subjected to plasma treatment and thermal annealing. The changes of the surface polarity and the surface free energy, the surface morphologyand roughness were studied using electrokinetic analysis, goniometry, AFM. XPS and RBS methods. Ablation of PMP surface layers was determined by gravimetry. The influence of heating on the surface morphology of the plasma treated PMP and its wettabilityand stability was studied too. The adhesion and proliferation of vascular smooth muscle cells (VSMC) on the plasma treated polymer was investigated too. The plasma treatment causes only ablated polymer mass increases with the increasing plasma power andexposure time. The plasma treatment increases oxygen concentration on the PMP surface, with the oxygen concentration decreasing towards to the polymer bulk. The thermal annealing results in only minor changes in the PMP surface morpholog
