Antibacterial Coating for Elimination of Pseudomonas aeruginosa and Escherichia coli

Abstract EN

A polymer antibacterial surface has been successfully developed.

The coating system used silane as binder and Ag particles as antibacterial agent.

The silver was synthesized using precipitation method.

X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), Brunauer-Emmett-Teller (BET) tests, energy-dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS) were carried out to evaluate the silver particles.

Antibacterial properties of the coating system were tested against gram-negative bacteria, namely, Pseudomonas aeruginosa and Escherichia coli.

Different amounts of Ag were used in the coating to optimize its usage.

The Japanese International Standard, JISZ2801, was used for bacteria test and the surface developed complies with the standard being antibacterial.
