  • Patent number: 11046854
    Abstract: The present invention provides polymer-based slippery liquid-infused porous surfaces (SLIPS) that can prevent adhesion and colonization by fungal and bacterial pathogens and also kill and/or attenuate the colonization and virulence of non-adherent pathogens in surrounding media. The present approach exploits the polymer and liquid oil phases in these slippery materials to sustain the release of small molecules such as a broad-spectrum antimicrobial agent, an antifungal agent, an antibacterial agent, an agent that modulates bacterial or fungal quorum sensing, an agent that attenuates virulence, or a combination thereof. This controlled release approach improves the inherent anti-fouling properties of SLIPS, has the potential to be general in scope, and expands the potential utility of slippery, non-fouling surfaces in both fundamental and applied contexts.

  • Publication number: 20200299520
    Abstract: This invention provides slippery liquid-infused porous surfaces (SLIPS) using nanoporous or microporous and chemically reactive polymer multilayers. This approach permits fabrication of slippery anti-fouling coatings on complex surfaces and provides new means to manipulate the mobilities of contacting aqueous fluids. The results expand the range of tools that can be used to manipulate the behaviors of SLIPS and open the door to new applications of this emerging class of soft materials.

  • Patent number: 10487217
    Abstract: The present invention provides multilayer polymer films, materials and coatings which exhibit robust underwater superoleophobicity and have remarkable structural functional tolerance to a broad range of physical, chemical, and environmental challenges encountered by surfaces deployed in aqueous or aquatic environments. These materials can be fabricated on surfaces of arbitrary shape, size, and composition and provide straightforward means to manipulate surface chemistry and fine-tune other useful features of the interfacial behavior (e.g., underwater oil-adhesiveness). These materials address key obstacles to the application of non-wetting surfaces and anti-fouling ‘super-phobic’ materials in practical, real-world scenarios.
