Résumé

Phase-change emulsions are a novel type of heat storage material and heat transfer fluids. In particular, oil-in-water emulsions are latent heat storage materials that have low melting points. In this paper, the influences of the phase-change characteristics over the long term on nano-emulsion stability are investigated. The phase-change nano-emulsion is prepared by the phase inversion temperature method. The stability of emulsification of tetradecane with nonionic surfactants is confirmed for a droplet size distribution as a function of time. The droplet size of the nano-emulsion is measured by dynamic light scattering. The relationships between the phase-change characteristics and the stability of the emulsion are discussed in detail. The results reveal that the phase-change characteristics have a significant effect on the stability of the emulsion. Moreover, the surfactant concentration is found to contribute to the stability of the phase-change nano-emulsion.
