Abstract
The biomaterial coatings for bone tissue regeneration described in this study promotebioactivity. The ceramic-polymer composite coatings deposited on polylactide (PLA) plates containpolymers, namely polyvinylpyrrolidone (PVP)/polyethylene glycol (PEG), while the ceramic phaseis hydroxyapatite (HA). Additionally, collagen (COL) and glutathione (GSH) are components ofhigh biological value. Bone tissue materials requires additionally demanding tribological properties,which are thoroughly described in this research. These findings, presented herein for the first time,characterize this type of highly specific composite coating material and their indicate possible applica-tion in bone regeneration implants. Implementation of the collagen in the PVP/PEG/HA compositematrix can tailor demanding tribological performance, e.g., anti-wear and friction reduction. Theaddition of the ceramic phase in too high a content (15%) leads to the decreased swelling ability ofmaterials and slower liquid medium absorption by composite coatings, as well as strong surfaceroughening and loosening tribological properties. In consequence, small particles of HA from thevery rough composite crumble, having a strong abrasive effect on the sample surface. In conclusion,sample C composed of PVP/PEG/GSH/COL/HA (5%) exhibits high bioactivity, strong mechanicaland tribological properties, the highest free surface energy, porosity, and accepted roughness to beimplemented as a material for bone regeneration.
