NOVELTY - Paraffin wax Pickering emulsion with photo-thermal conversion function comprises 10-40 wt.% paraffin wax, 1-5 wt.% magnesium-aluminum layered double metal hydroxide, not less than 0-0.1 wt.% graphene oxide and balance of water. USE - Paraffin wax Pickering emulsion with photo-thermal conversion function. ADVANTAGE - The paraffin wax Pickering emulsion with photo-thermal conversion function is prepared by the method that is simple, and replaces the chemical emulsifier with magnesium-aluminum layered double metal hydroxide and graphene oxide to prepare Pickering emulsion of paraffin wax with a low supercooling degree, low viscosity, high thermal conductivity and high stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing paraffin wax Pickering emulsion, which involves adding magnesium-aluminum layered double metal hydroxide to dissolve and disperse in water to prepare solution A; adding graphene oxide to solution A, dissolving and dispersing to prepare solution B; adding paraffin to solution B, and heating to above the melting point of the paraffin; and stirring and emulsifying to obtain the desired product.
