The Fabrication of Multifunctional SLIPS Films by Electrospinning

Abstract The pitcher plant has inspired anti‐wetting coatings. However, it is still a challenge to create oleophobic surfaces that repel non‐polar liquids due to their low surface tension. Here we develop an effective strategy to fabricate multifunctional fibrous films by electrospinning polyvinylidene fluoride (PVDF) and polyvinyl acetate (PVAc) polymers. The as‐prepared multifunctional films combined the Janus behavior with hydrophobicity on the upper side and thermally adhesive properties on the lower side. By spraying with lubricant, a pitcher‐plant‐like omniphobic surface has been prepared, which exhibited excellent anti‐wetting properties against water, low surface tension and complex fluids. Furthermore, the transparency of the film has been greatly enhanced after lubrication, which was suitable for glass‐based anti‐fouling materials or coatings.
