“…[15,16] EPD consists of the movement of charged particles suspended in liquid and deposition onto a conducting substrate under the influence of an externally applied electrical field. [17,18] The advantages of this method are high purity, easy control of the coating thickness, high coating uniformity, the possibility of using complex shaped substrates, and the short deposition time of coatings.…”

“…[32] According to our knowledge, there are very few papers available in the literature on the EPD of composite bioglass/PEEK coatings. [15,33] The main focus of the referred studies was the investigation of EPD parameters and the final quality of the composite coatings. However, there is no information about the EPD of sol-gel glass/PEEK coatings.…”

In this study, microporous composite sol-gel glass/polyetheretherketone (SGG/PEEK) coatings were produced on the Ti-13Nb-13Zr titanium alloy by electrophoretic deposition. Coatings with different levels of high open porosity were developed by introducing SGG particles of varying diameters into the PEEK matrix. The microstructure of the coatings was characterized by electron microscopy and X-ray diffractometry. The coatings with 40-50 lm thickness were composed of semicrystalline SGG particles consisting of hydroxyapatite, CaSiO 3 , some Ca 2 SiO 4 , and an amorphous phase containing Ca, Si, P, and O, homogeneously embedded in a semicrystalline PEEK matrix. The size of SGG particles present in the coatings strongly influenced the formation of microcracks and their adhesion to the underlying substrate. Microscratch tests showed that the coating containing SGG particles with a diameter smaller than 45 lm and open porosity of 45 pct exhibited good adhesion to the titanium alloy substrate, much better than the coating containing particles with a diameter smaller than 85 lm and total open porosity equal to 48 pct. The corrosion resistance was investigated in Ringer's solution at a temperature of 310 K (37°C) for a pH equal to 7.4 and in deaerated solutions with the use of open-circuit potential, potentiodynamic polarization, and electrochemical impedance spectroscopy. The SGG/PEEK-coated alloy indicated better electrochemical corrosion resistance compared with the uncoated alloy.

“…Densification of the coatings was carried out as a post-EPD process and to improve the adhesion of the coatings to the substrate. The sintering temperature was 3408C, sintering time 20 min and heating rate 3008C h 21 (Boccaccini et al 2006c). PEEK, a biocompatible and stable polymer that has been deposited by EPD Corni et al 2009), is suitable for several medical device applications since it combines outstanding chemical and hydrolysis resistance, high strength and excellent tribological properties.…”

To impart bioactivity to PEEK coatings, Bioglass particles have been incorporated to the coating (Boccaccini et al 2006c). Figure 5 shows scanning electron microscope (SEM) images at different magnification of a PEEK/Bioglasscoated NiTi wire obtained by EPD (20 V, time ¼ 5 min, PEEK concentration in ethanol ¼ 6 wt%, Bioglass concentration ¼ 1 wt%).…”

Electrophoretic deposition (EPD) is attracting increasing attention as an effective technique for the processing of biomaterials, specifically bioactive coatings and biomedical nanostructures. The well-known advantages of EPD for the production of a wide range of microstructures and nanostructures as well as unique and complex material combinations are being exploited, starting from well-dispersed suspensions of biomaterials in particulate form (microsized and nanoscale particles, nanotubes, nanoplatelets). EPD of biological entities such as enzymes, bacteria and cells is also being investigated. The review presents a comprehensive summary and discussion of relevant recent work on EPD describing the specific application of the technique in the processing of several biomaterials, focusing on (i) conventional bioactive (inorganic) coatings, e.g. hydroxyapatite or bioactive glass coatings on orthopaedic implants, and (ii) biomedical nanostructures, including biopolymer-ceramic nanocomposites, carbon nanotube coatings, tissue engineering scaffolds, deposition of proteins and other biological entities for sensors and advanced functional coatings. It is the intention to inform the reader on how EPD has become an important tool in advanced biomaterials processing, as a convenient alternative to conventional methods, and to present the potential of the technique to manipulate and control the deposition of a range of nanomaterials of interest in the biomedical and biotechnology fields.
