In present study was showed the results of research the stability of nanoPCMs in terms of types and concentrations of surfactant used. For stearic acid has been added PVP or oleic acid in concentrations of 0%, 5% and 10%. Nanoparticles TiO2 and Al-2O3 in concentration of 1% were chosen to be researched in this test. The mixing of nanocomposites has been done in an ultrasonic scrubber in which the samples were placed for 45 mins. The stability was researched through the measurement the changing of temperature over time. The measurements have been done in controlled thermostatic conditions. The results were obtained after clotting the samples from 70°C to 20°C and melting the samples form 20°C to 70°C. The expected results was obtaining plot waveforms with reduced loading time for materials containing surfactants and nanoparticles at their core.
