An environmentally friendly coating: Excellent self-cleaning, efficient antimicrobial, and durability properties
The development of non-polluting and non-toxic polymer antimicrobial agents is a prominent focus in contemporary research and development. Polymer quaternary ammonium salts are particularly promising for their antimicrobial efficacy. In this study, we synthesized quaternary imidazole derivatives using butylimidazole and 3-chloropropyltriethoxysilane. We then prepared PDMS/BIS/PPS hydrophobic antimicrobial composite coatings by incorporating quaternary ammonium salt chemically grafted silica (BIS), polyphenylene sulfide (PPS), and polydimethylsiloxane (PDMS). The resulting composite coating displayed a high contact angle of 136.4°±1° and a low sliding angle of less than 5°±1°, indicating its hydrophobic nature. Electrochemical assessments demonstrated exceptional corrosion resistance, with a corrosion inhibition rate of 99.967 %. Bacterial assays confirmed the coating's effectiveness in inhibiting bacterial proliferation, especially against E. coli. The quaternary ammonium-modified silica particles in the coating facilitate bacterial adsorption through electrostatic interactions, which compromise cell membrane permeability, obstruct nutrient uptake, and induce apoptosis. With its anti-fouling, self-cleaning, and anti-corrosion properties, this coating has substantial potential for applications in various fields, including medical devices, and food packaging.
期刊介绍:
The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results.
Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
