Abstract
Three different glasses were synthesized by doping 45S5 bioactive glass with B2O3. The bioactivity of the glasses was evaluated by immersion in simulated body fluid (SBF) up to 3 days; all glasses showed the precipitation of hydroxyapatite (HAp) after one day of soaking in SBF. Electrophoretic deposition (EPD) was used to prepare PEEK/B2O3-doped 45S5 glass composite coatings on stainless steel substrates. The coatings were characterized by means of tape test (ASTM D3359-B), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), contact angle measurements, thermogravimetric analysis and in vitro bioactivity test. All composite coatings exhibited a porous and homogenous structure with a hydrophobic surface, according to the wettability test. The in vitro test in SBF demonstrated that the coatings were highly bioactive.
