The 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.

本研究的目的是在氟硅烷化瓷基材上制造光滑的注入润滑剂的多孔表面 (SLIPS) 涂层，以使用一种以前未曾报道过的不太复杂和廉价的方法防止生物膜粘附。SLIPS 涂层在抑制由藻类和细菌诱导的生物膜方面的巨大潜力在经过修改的 BG11 环境中静态和动态地得到证明。SLIPS涂层对微生物粘附和菌落形成的抑制机制是基于其液体状表面作为主要贡献者。毒性试验研究表明，所用润滑剂的毒性与此无关。研究了培养基中细菌和润滑剂类型对 SLIPS 涂层上藻类沉降程度的影响。结果表明，施加的 SLIPS 涂层可以将藻类生物膜的沉降速度减慢 90%。此外，在存在细菌的情况下，这个百分比下降到 75%。润滑剂类型对生物膜沉降没有显着影响普通小球藻或与大肠埃希菌混合培养（P > 0.05）。该结果将为功能应用和润滑剂选择指导提供基础数据，以制造 SLIPS 涂层，以抑制陶瓷基底（如瓷绝缘体）上的生物膜形成。
