Cell behaviour on bioactive polymeric coatings.

Implants modified with polymeric nanofibers coating containing the antibiotic vancomycin

Objective(S): Implant-related infections are disastrous complications in the clinic. One recent strategy to reduce the rate of infection is using the bioactive coating with an antibiotic. The purpose of these bioactive surfaces is to prevent bacterial adhesion to the implant and, consequently, the development of biofilm. In this study, vancomycin-loaded polymeric coating on imp...

TiO2 Pigment Suspension Behaviour upon Adsorption of Polymeric Dispersants

The influence of polymeric dispersants containing different functional groups on TiO2 pigment particle suspension was investigated at pH 6.0 and 9.5, using rheology and particle size data. The dispersants chosen were polyacrylic acid and modified polyacrylamides including homo and copolymers modified with carboxylate and/or hydroxyl groups. The pigment suspension was strongly affected by both p...

Investigation of the electrical properties and corrosion resistance of TiN coating deposited by reactive sputtering on the titanium bipolar plate, used in polymeric fuel cell

The effect of titanium nitride film on the properties of titanium bipolar plates used in polymeric fuel cell was investigated in this research. TiN coatings was deposited on the Ti-grade 1 substrate by using DC-sputtering method. Pure titanium was used as target and coating deposition was done in argon and nitrogen atmosphere. Different TiN thickness was developed by changing sputtering time. T...

Bioactive composite gradient coatings of nano-hydroxyapatite/polyamide66 fabricated on polyamide66 substrates.

Tightly bonding of bioactive coating is the first crucial need for orthopaedic implants. This study describes a novel and convenient technique to prepare bioactive coating with high adhesion on orthopaedic substitutes made of polymeric matrix. Here, a chemical corrosion method has been adopted to fabricate a coating on the surface of injection-moulded polyamide66 (PA66) substrates by corrosive ...
