通过在等离子体处理的聚乙烯 (PE) 和聚氨酯 (PU) 基材上静电纺丝聚二甲基硅氧烷 (PDMS) 和聚苯乙烯 (PS) 作为载体聚合物，制备疏水性纤维滑液注入多孔表面 (SLIPS)。随后将黑籽油 (BSO) 注入多孔结构中以制备 SLIPS。注入润滑剂的 SLIPS 可充当防护层，在防止生物膜形成方面发挥重要作用。研究了静电纺丝过程中使用的聚合物溶液的效果，以获得明确的疏水纤维结构。通过各种光学、宏观和光谱技术分析表面特性。在优化条件下对选定的样品进行了表面化学、表面形态/形貌和机械性能的全面研究。使用四氢呋喃 (THF) 溶剂以 1:1:10 (g/g/mL) 比例的 PDMS/PS 混合物制备的电纺纤维在纤维均匀性方面显示出最佳结果。随后将 BSO 注入制造的 PDMS/PS 纤维垫中，表现出对水滴的光滑行为。此外，制备的 SLIPS 对金黄色葡萄球菌和大肠杆菌菌株表现出抗菌活性。
Hydrophobic fibrous slippery liquid-infused porous surfaces (SLIPS) were fabricated by electrospinning polydimethylsiloxane (PDMS) and polystyrene (PS) as a carrier polymer on plasma-treated polyethylene (PE) and polyurethane (PU) substrates. Subsequent infusion of blackseed oil (BSO) into the porous structures was applied for the preparation of the SLIPS. SLIPS with infused lubricants can act as a repellency layer and play an important role in the prevention of biofilm formation. The effect of polymer solutions used in the electrospinning process was investigated to obtain well-defined hydrophobic fibrous structures. The surface properties were analyzed through various optical, macroscopic and spectroscopic techniques. A comprehensive investigation of the surface chemistry, surface morphology/topography, and mechanical properties was carried out on selected samples at optimized conditions. The electrospun fibers prepared using a mixture of PDMS/PS in the ratio of 1:1:10 (g/g/mL) using tetrahydrofuran (THF) solvent showed the best results in terms of fiber uniformity. The subsequent infusion of BSO into the fabricated PDMS/PS fiber mats exhibited slippery behavior regarding water droplets. Moreover, prepared SLIPS exhibited antibacterial activity against Staphylococcus aureus and Escherichia coli bacterium strains.
