A reversible cycle phase change liquid comprises a polar working fluid, nanoparticles of a material having a density greater than 3000 kg/m.sup.3, and a controllable gel. The gel is switchable between hydrophilic and hydrophobic phases by application of a phase change driver. The gel coats the nanoparticles to a first thickness when the gel is in the hydrophilic phase and is swollen by the polar working fluid, and coats the nanoparticles to a reduced thickness when in the hydrophobic phase. The coated nanoparticles form clusters, or comprise individual unclustered nanoparticles, when the gel is in the hydrophilic phase, and form larger clusters when the gel is in the hydrophobic phase. In embodiments aggregation of the nanoparticles into clusters is self-limiting because of electrical charges on the nanoparticles, such that when the gel is in the hydrophobic phase the clusters remain soluble within the liquid.
