Abstract:
1. A method for encapsulating an epoxy, which method comprises the steps of: (a) providing a suspension of droplets of the epoxy to be encapsulated; (b) stabilizing the suspension of droplets with a surfactant and adding a polymer which is non ionogenic or has the same charge as the surfactant; (c) adding a layered inorganic material and magnetically addressable nanoparticles to the stabilized suspension obtained in step (b); and (d) subjecting the suspension obtained in step (c) to a treatment which establishes that a shell of a hybrid material is formed around the droplets, which hybrid material comprises at least part of the layered material, at least part of the surfactant, the polymer, and magnetically addressable nanoparticles, wherein the shell is capable of protecting the encapsulated liquid against heat, moisture, oxygen and light and the epoxy is released upon compression forces to react as a glue with surfaces surrounding the capsule and wherein the weight ratio of inorganic material (A) and the surfactant (B) is in the range of from 90/10 to 60/40 (A)/(B).
