The Influence of Surface Wettability and Topography on the Bioactivity of TiO(2)/Epoxy Coatings on AISI 316L Stainless Steel

Epoxy/TiO(2)/epoxy and epoxy/FAS-TiO(2)/epoxy coatings were applied to the surface of AISI 316L stainless steel with the aim to improve the biocompatibility and antibacterial properties. Contact-angle measurements were used to evaluate the wetting properties of the epoxy, epoxy/TiO(2)/epoxy and epox...

description Epoxy/TiO(2)/epoxy and epoxy/FAS-TiO(2)/epoxy coatings were applied to the surface of AISI 316L stainless steel with the aim to improve the biocompatibility and antibacterial properties. Contact-angle measurements were used to evaluate the wetting properties of the epoxy, epoxy/TiO(2)/epoxy and epoxy/FAS-TiO(2)/epoxy coatings. The epoxy and epoxy/TiO(2)/epoxy coatings were hydrophilic compared with the strongly hydrophobic epoxy/FAS-TiO(2)/epoxy coating. The average surface roughness (S(a)) of the epoxy/FAS-TiO(2)/epoxy coating was higher than that of the epoxy/TiO(2)/epoxy coating due to the formation of agglomerates. The biocompatibility evaluation revealed that the cell attachment was significantly higher on the epoxy/FAS-TiO(2)/epoxy and epoxy/TiO(2)/epoxy coatings compared with the pure epoxy coating. We also observed improved antibacterial properties for the epoxy coatings with the addition of both TiO(2) and FAS-TiO(2) nanoparticles.
