Rupturable, dual reagent mono-capsules are disclosed that have a core composition, which includes a carboxylic acid, encapsulated within a phenolic resin-containing polymer wall that ruptures upon exposure to alkaline conditions over a period of time, and a shell connected to an exterior surface of the polymer wall by a surfactant. The shell is made from a mineral containing a metal that is chemically bonded to the surfactant by a chemical electrostatic interaction. Upon rupture of the polymer wall of the mono-capsule, the carboxylic acid and the mineral containing the metal chemically react with one another to form a reaction product that seals a rupture in the capsule and/or seals a feature of a surface upon which the capsules are disposed.

Microcapsules are disclosed that have a core composition encapsulated within a polymer wall, and an inorganic shell connected to an exterior surface of the polymer wall by a surfactant. The inorganic shell has a cation attracted to the surfactant and an anion or anion equivalent chemically bonded to the cation to form the shell or has the metal portion of a metal-containing compound attracted to the surfactant to form the shell. The shell may comprise a Ca, Mg, or Ag metal compound. The shell may be a graphene oxide-metal compound.
