摘要: Abstract This paper deals with the surface characterization of biocompatible polymer substrate poly(L-lactic acid) (PLLA) altered by gold sputtering combined thermal treatment. The influence deposition treatment on morphology is studied. thickness layer was determined atomic force microscopy study. Surface sheet resistance sputtered layers studied two-point technique method. heat induced changes were microscopy. stress dramatically structure PLLA's surface. With increasing ripple-like pattern appears and roughness biopolymer significantly increases. These structures are interesting for tissue engineering.
