    摘要: A self-healing coating includes a polymer matrix, a polymerizer, and a set of capsules containing a corresponding activator for the polymerizer. The polymerizer may be present in another set of capsules, or the polymerizer may be phase separated from the polymer matrix. The coating may be prepared by depositing a coating composition on a substrate and solidifying the coating composition, where the coating composition includes the polymerizer, the activator capsules and a matrix precursor. A combination of polymerizer capsules and activator capsules may be part of a kit, which may be used to provide self-healing properties to a coating. The polymerizer and the activator may be wet-curable, and coatings containing the polymerizer and activator may be able to self-heal when in contact with water.

    摘要: A method of making core-shell capsules containing a water-immiscible liquid, comprising the steps of (a) dispersing into the water-immiscible liquid a crosslinking agent that is inactive under the conditions of the dispersion; (b) emulsifying the resulting dispersion into an aqueous solution of a crosslinkable hydrocolloid; and (c) activating the crosslinking agent to cause the hydrocolloid to crosslink at the dispersion/solution interface. The method is simple and provides capsules that can be cold-loaded. The capsule material may be made of vegetable-derived materials.

    摘要: A novel method of forming water in oil microcapsules is disclosed. According to the invention microcapsules are obtained by steps comprising dispersing an oil soluble amine modified polyfunctional polyvinyl monomer and an oil soluble bi- or polyfunctional vinyl monomer along with a thermal or UV free radical initiator (optionally included in one or both of the oil or water phases) and an organic acid into an internal phase oil; heating or UV exposing for a time (and temperature) sufficient to oligomerize the amine modified polyfunctional polyvinyl monomer and oil soluble bi- or polyfunctional vinyl monomer forming a pre-polymer. Thereafter the process involves adding to the oil phase oil a water phase comprising a dispersion in water of an anionic emulsifier (and optionally initiator), and adding an emulsifying agent. Emulsifying the water phase into the oil phase (W/O) is controlled through the quantity of water employed. The emulsion is then UV exposed or heated for a time (and temperature) sufficient to decompose the free radical initiators in the oil and/or water phases; thereby forming microcapsule wall material at the interface of the water and oil phases.

    摘要: The invention teaches an encapsulated curable adhesive composition especially adapted for use as a structural adhesive. The adhesive composition enables formation of a thin layer reactive composition of microcapsules and a two-part curative. The adhesive composition comprises a first population of microcapsules encasing a monomer and a first-part curative comprising an initiator. The adhesive composition further comprises a second-part curative. The second-part curative comprises an activator and a catalyst. At least the activator of the second-part curative is preferably encapsulated in a second population of microcapsules. The catalyst and the second population of microcapsules can be dispersed in a binder material, along with the first population of microcapsules. The first population of microcapsules contain encapsulated within the core a monomer having a Tg 35°C or less and the first-part curative. The first population microcapsules contain encapsulated within the core a monomer having a Tg 35°C or less along with the first-part curative. The encapsulated monomer and first-part curative constitute a blend which is a free flowing liquid having a viscosity of less than 500 Cp (milliPascal-second), and more preferably less than 10 Cp (milliPascal-second). The first population of microcapsules with first-part curative, and a second-part curative and second population of microcapsules are dispersed in a binder material. Reactive contact of the monomer and first-part curative with the second-part curative is affected by exuding the respective capsule contents into reactive contact through breakage of the microcapsules such as an interference fit of the substrate or substrates to which the composition is applied.

    摘要: Microcapsules for smart textile materials, containing an active product and with reactive groups, with the objective of chemically binding the microcapsules to the fibres. The microcapsules contain active products such as PCM (phase change materials), or can be of controlled release of products such as fragrances, essential oils, antibacterial and others with the objective to add specific functional properties to the textile materials. They can be applied by padding and spraying followed by thermofixation . In case of products such as knitwear the application process can also be by exhaustion process, given that the microcapsules acquire affinity towards the fibres and react with the fibres during the process. The chemical bond of the controlled release microcapsules with the fibres confers them a higher resistance to washing than the existing microcapsules glued to the fabric by printing or padding.
