Abstract:Liquid marble was first prepared by encapsulation of water droplet using hydrophobic silicon dioxide particles as the stabilizer of liquid-gas interface. Then the as-prepared liquid marble was packaged using a polymer coating by moisture curing of ethyl α-cyanoacrylate on its surface. A coating of acrylated epoxidized soybean oil was further prepared on the marble surface by photocuring method to finally form a water-bearing capsule. The double-bond conversion of the UV-cured coating was investigated by the real-time FT-IR. The basic properties such as hardness and water resistance were studied. The morphologies of the liquid marble and water-bearing capsule were characterized by digital photography, optical microscopy, and scanning electron microscopy. The mechanical performance and water retention capacity of the water-bearing capsule were also studied. The results showed that the surface of as-prepared water-bearing capsule was smooth and compact, compared with that of original liquid marble. The poly(ethyl α-cyanoacrylate) coating and UV-cured coating of acrylated epoxidized soybean oil endowed the water-bearing capsule with both excellent water vapor barrier property and mechanical performance, making it a great potential to be applied in cosmetics, pharmacy and cigarette.
