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...

A TEOS-GPTMS nano-hybrid thin film was deposited on the polymethyl methacrylate (PMMA) substrate by a sol-gel dip coating method. Morphology, roughness and surface chemical bonding of the thin films were evaluated by X-ray diffraction (XRD), field emission scanning electron microscopy(FE-SEM), atomic force microscopy, and Fourier transform infrared spectroscopy methods, respectively. UV-vis spe...

UNLABELLED Platelet adhesion on the cardiopulmonary bypass oxygenator membrane is associated with impaired hemostasis. We investigated the effects of heparin coating of the oxygenator membrane on protein adsorption and platelet adhesion on the surface. Noncoated and heparin-coated polypropylene membranes were incubated in whole blood with small- (1 U/mL) or large-dose (5 U/mL) heparin as an ant...

In this study, functionally graded Ni-Al2O3 composite coating (FGN-A) has been produced from nickel Watt’s bath containing different concentrations of Al2O3 particles. For this, different composite coatings were electroplated in the same bath with different particles concentration to find the optimum concentration of particles in which the maximum content with uniform distribution of Al2O3 part...

Problem statement: Dammar is a natural resin that used anciently in varnish production. The use of dammar natural resin in coating is limited by undesirable properties for application in coating where it is considered very brittle. Due to dammar's brittle nature, an aged dammar coating can be easily scratched or abraded. Approach: Dammar natural resin could be modified into SiliconeDammar by us...

Epoxy powder coatings containing zinc aluminum phosphate (ZAP) and zinc phosphate (ZP), which are the 2nd and 1st generation of phosphate-based pigments respectively, were applied to the surface of mild steel sheets. The anticorrosive performances of the coated samples were studied using electrochemical impedance spectroscopy (EIS). Cathodic disbonding resistance and the adhesion performance of...

In this study, the microstructural, mechanical, adhesion, and hemocompatibility properties of nanocrystalline diamond coatings were examined. Microwave plasma chemical vapor deposition (MPCVD) was used to deposit nanocrystalline diamond coatings on silicon (100) substrates. The coating surface consisted of faceted nodules, which exhibited a relatively wide size distribution and an average size ...

Polypropylene (PP) has poor adhesion to metals and other surfaces for its chemical structure. Hence, chemical modification of PP is necessary for metal surface coating application. In this research, grafting of maleic anhydride (MA) onto co(propylene-b-ethylene) in the presence of a dicumyl peroxide (DCP) was accomplished in a single screw extruder. Characteristics of the modified polymer were ...
