The studied nanocomposite membranes were produced from PCL, and contained identical amounts of carbon nano-additives: MWCNTs/MWCNTs-f, CNFs/CNFs-f. The wettability measurements proved to be not sufficient to distinguish materials features. The Raman micro-spectroscopy was selected to uncover interaction at the carbon particle – polymer matrix interphase. Analyzing the interaction of carbon nanoparticles with the polymer matrix, one can see the specificity and the different nature of this interaction, depending on the type of nanoparticle and on its functionalization, which results in material properties. This conclusion was also confirmed by the clear colonization of the human U-2 OS cells on tested nanomaterials.
