Abstract: The present invention relates to a process for producing NTRA by interfacial polymerisation of a cyanoacrylate monomer at the interface between the mixture of organic material and colloidal oxide nanoparticles with the aqueous medium, in the form of an emulsion, the colloidal oxide nanoparticles being optionally included. The NTRA synthesis process comprises six successive processing steps: a) solubilising the organic material and dispersing the colloidal oxide nanoparticles in a solvent, the organic phase; b) pre-emulsifying the organic phase in a solution of water and emulsifiers; c) diffusing this pre-emulsion in an aqueous phase containing emulsifiers; d) distilling the solvents; and finally e) polymerising the monomer and forming the shell of the nanoencapsulated products, with f) optionally drying the product. The resultant NTRA can be in the form of a colloidal dispersion in an aqueous medium or in the form of nanoparticles.

Abstract: The present invention relates to a nanoencapsulated temperature regulating agent which presents a nanoencapsulated temperature regulating agent (ARTN/NTRA) that aggregates, in a same nanostructure, an organic material capable of undergoing melting by absorbing heat, or solidification by releasing heat, and IR radiation screening nanoparticles, a colloidal oxide capable of reflecting the infrared radiation which causes surfaces exposed to a heat source to heat up. The NTRA produced may be either in the form of a colloidal dispersion in an aqueous medium or in the form of nanoparticles, if the aqueous dispersion of the NTRAs is subjected to any drying process such as spray-drying, fluidized-bed drying, filtration, lyophilization, centrifugation, inter alia. The association of temperature regulating mechanisms and the fact that the NTRA is on a nanometric scale imparts greater efficiency for heat transfer processes and surface-covering power, guaranteeing greater reflection of infrared radiation.

Abstract: The present invention describes an approach to the design of temperature regulation systems combining, in a single structure, a heat absorption or release system by fusion or solidification of a particular material and also a particulate oxide that contributes to reflecting infrared radiation. The production of the thermofunctional nanostructure comprises six successive processing steps: a) pre-emulsifying the organic material and dispersing the colloidal oxide nanoparticles in an aqueous phase, the pre-emulsion; b) reducing droplet size in the pre-emulsion by high-pressure homogenisation; c) adsorbing the monomer in the resultant emulsion; d) polymerising and forming thermoftmctional nanostructures; e) cooling the nanosuspension containing the thermofunctional structures; and optionally f) drying the product.
