    摘要: The present invention provides liquid repellent slippery surfaces and methods or preparing the same. The surface comprises a substrate, the substrate surface being functionalised via the deposition of a polymer layer thereon, and a lubricant impregnated into the polymer layer, thereby forming said liquid repellent slippery surface. The polymer layer comprises an aromatic ring-containing polymer layer; and the lubricant is an aliphatic compound, rapeseed oil, olive oil, vacuum pump oil, cinnamaldehyde a cinnamaldehyde derivative, essential oil or an essential oil-derived compound. The present invention also provides a liquid repellent slippery surface, wherein the surface comprises a substrate and associated substrate surface, the substrate surface functionalised via the deposition of a polymer layer thereon. The polymer layer is formed from a functional monomer precursor comprising a siloxane-group containing monomer or an alkyl-group containing monomer.

    摘要: According to some embodiments, an anti-microbial composition (e.g., an anti- microbial coating), and related methods, are generally described. The anti-microbial composition may be used to kill, inhibit growth, mitigate, and/or inhibit retention of one or more microbes and/or bacteria. The anti-microbial properties of the composition may be provided by a microbial inhibition material, which comprises a silane compound (e.g., a first silane compound) functionalized with a metal ion. The composition may also include a fingerprint inhibition material, which comprises a silane compound (e.g., a second silane compound) that may preferably be hydrophobic. The fingerprint inhibition material may comprise an invisible fingerprint material and/or an anti-fingerprint material. The invisible fingerprint material is configured to hide fingerprints by making them optically less visible (e.g., to the human eye), while the anti-fingerprint material may be configured to suppress the retaining of fingerprints. In addition to providing anti-microbial and anti-fingerprint properties, the composition may also be chemically inert, mechanically robust, and/or optically transparent.
