Модифицирование PLLA скаффолдов методом DC магнетронного распыления титановой мишени в смеси рабочих газов

Abstract

In this work effect of an inert gases impurity in the plasma of a DC magnetron discharge arising from the sputtering of the titanium target in a nitrogen atmosphere on the morphology and chemical composition of electrospun PLLA scaffold was investigated. Scanning electron microscopy shown that the selected technological modes make it possible to modify polymer PLLA scaffolds without changing their morphological properties. X-ray fluorescence analysis method shown the stability of the chemical structure of the scaffold and the change in the titanium concentration depending on the gases atmosphere.
