Electrophoretic deposition (EPD) is a simple, low cost technique used to obtain coatings at room temperature . In composite coatings for orthopaedic applications, a bioactive material such as Bioglass  (BG) is combined with a biopolymer such as poly (ε-caprolactone) (PCL). BG promotes bioactivity forming a phase of apatite hydroxycarbonate (Hap) on its surface while the polymer acts as a support and avoids the densification process of the coating, at the same time PCL has potential uses in controlling release of drugs .It was possible to obtain EPD coatings of a neutral polymer such as PCL by adsorbing it on the BG particles. By means of a bioactivity test, it was possible to corroborate the development of crystalline structures associated with mineral phases of the Hap, these precipitates forms a dense layer on the surface of the coatings, confirming their potential use in orthopaedic applications.
