摘要: Abstract Sodium p-styrene sulfonate (SSS) was successfully grafted on the surface of 316 stainless steel surfaces (SS-SCA-SSS) via Thiol-ene click reactions with aim to improve its antibacterial properties. Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron (XPS), laser scanning confocal microscopy (LSM) and contact angle measurements were employed analyze physico-chemical characteristics modified SS. The properties SS-SCA-SSS evaluated using a bacterial strain Escherichia coli (E. coli). efficiency results showed that exhibited satisfactory long-term capability against E. coli. Bacterial adhesion both reused reduced 18% those positive obtained in this study indicate high potential SSS grafting SS for practical usages.
