Description	This work deals with the surface characterization of biocompatible polymers: poly(L-lactide acid) (PLLA) and poly-4-methyl-1-pentene (PMP). Plasma irradiation and thermal treatment influences the surface wettability, morphology (AFM), chemical composition of surface (XPS) and electrokinetic (zeta) potential. After plasma treatment the surface morphology of PLLA changes dramatically. Plasma treatment generates oxygen groups on the surface of PMP and causes both PMP and PLLA ablation. The thermal treatment accelerates the aging of the polymer surface and dramatically changes the structure of modified PLLA. Plasma treatment improves significantly the cell adhesion and proliferation on the PMP. The biocompatible polymers are of a great importance in a tissue engineering and materials science. Both the plasma exposure process and thermal treatment was successfully applied for the polymer surface modification. The changes in physico-chemical surface properties caused by the treatment had a positive effect on polymers' biocompatibility, cell growth and adhesion.
