Abstract
This paper is focused on the surface characterization of plasma and consequently thermally treated biocompatible polymers. PLLA (poly(L-lactide acid) and PMP (poly-4-methyl-1-pentene) are studied. The influence of Ar plasma treatment on the surface polarity of substrate measured immediately after treatment and during the polymer surface aging is studied. Surface roughness, morphology, wettability, and surface chemistry were determined. Plasma treatment leads to significant changes in PLLA surface morphology and chemistry, with the PMP being slightly affected. The higher resistance to plasma fluence results in smaller ablation of PMP than that of PLLA. The plasma treatment improves cell adhesion and proliferation on the PMP. Plasma treatment of PLLA influences mostly the homogeneity of adhered and proliferated VSMC.
Highlights
The aim of the material engineering is to observe and modify the properties of materials with the purpose of consecutive application in different branches of science and engineering
The influence of plasma treatment on poly(L-lactide acid) (PLLA) and PMP surface polarity was studied with goniometry which can be determined by contact angle measurement [20,21,22,23]
The influence of Ar plasma and thermal treatment on the surface properties of PLLA and PMP was determined by different techniques
Summary
The aim of the material engineering is to observe and modify the properties of materials with the purpose of consecutive application in different branches of science and engineering. The nanotechnology involves the study of metals, semiconductors, special glasses, and polymers in different forms, which can be applied as biomaterials. The observations in this field are crucial for the applications in medicine, pharmacology, biology, tissue engineering [2], or material science. The biocompatibility of polymeric materials can be increased by excimer lamp irradiation [6] ion beam modification [7] or consequent carbon layer deposition [8] Such materials can be successfully applied in tissue engineering [9, 10]
