This study introduces a new approach of liquid encapsulation using an atm. pressure plasma (APP). The technique is similar to interfacial polymerization, though here one phase is liquid (that contains unsaturated C=C bonds) and the other phase is plasma (that contains free radicals). When combined, the atm. plasma can induce surface polymerization of an acrylate-based liquid, resulting in a thin polymeric skin on top of the liquid Measurements with an at. force microscope and a spectroscopic ellipsometer estimate the thickness of the skin formed on top of di(ethylene glycol) diacrylate to be 40-50 nm. To demonstrate an application of this method, we encapsulated hemispherical capsules of reactive adhesives on a glass substrate. These adhesives are based on thiol-acrylate and thiol-acrylate-epoxy systems that react in the presence of a strong base catalyst. Plasma-induced polymerization can encapsulate, immobilize, and isolate sep. droplets of resin and the catalyst in a latent (nonreactive) state. These capsules remain latent until they rupture in response to phys. contact. A tensile testing machine reports an adhesive strength of ∼ 2 MPa for the formulated resins after curing. The capsules reported here may be useful for storing functional liquids for just-in-time release, such as contact-sensitive adhesives, on-demand lubricants, or self-healing agents.
