? 2022 The Korean Society of Industrial and Engineering ChemistryThe aim of this research is to fabricate slippery lubricant-infused porous surface (SLIPS) coatings on the fluorosilanized porcelain substrates to prevent biofilm adhesion with a less complex and inexpensive method that has not been reported before. SLIPS coating's great potential for inhibiting biofilm induced by algae and bacteria was demonstrated in a modified BG11 environment statically and dynamically. The inhibition mechanism of SLIPS coating against microorganism adhesion and colonies formation was based on its liquid-like surface as the main contributor. Toxicity assay studies demonstrated that the toxicity of applied lubricants had nothing to do with it. The effects of bacteria in culture medium and type of lubricant on the degree of algae settlement over SLIPS coatings were investigated. It was indicated that applied SLIPS coatings could slow down algae biofilm settlement up to 90%. Also, in the presence of bacteria, this percent was declined to 75%. The lubricant type presented no significant effect against biofilm settlement of Chlorella vulgaris mono or its mixed cultivation with Escherichia coli (P > 0.05). The results will provide basic data for functional application and lubricant selecting instruction to fabricate SLIPS coatings for inhibition of biofilm formation on porcelain substrates such as porcelain insulators.
