Hydrogen peroxide assisted sol–gel coating of core-shell microcapsules of phase change materials (PCMs) is reported. A doubly coated paraffin core with an inner poly(melamine-formaldehyde) shell and an outer coating of peroxostannate, peroxoantimonate, their mixture or the respective metal oxides are reported. Triple coating of the paraffin core with a poly(melamine-formaldehyde) inner shell, tin oxide middle layer and graphene oxide outer coating is also achieved by hydrogen peroxide sol–gel processing. The latent heats of the microencapsulated PCMs ranged between 122 and 192 J g−1. The sol–gel process involves stabilization of the peroxostannate or peroxoantimonate sol in basic aqueous hydrogen peroxide and subsequent destabilization and deposition of the sol by addition of an antisolvent. Transformation to the metal oxide coating is conducted by chemical reduction with sodium sulfite or by mild heat treatment without leakage of the paraffin core.

The hydrogen bonding of hydroperoxo capped stannate nanoparticles to poly(melamine formaldehyde) - paraffin microcapsule.


  • H2O2 assisted sol–gel coating of phase change organic–inorganic phase change microcapsules.

  • Organic–inorganic, core-shell phase change microcapsules with up to 192 J g−1 latent heat.

  • SnO2 and reduced graphene oxide coating of paraffin - poly(melamine-formaldehyde) microcapsules.
