This work concentrates on the development of eutectic PCMs (ePCMs) that can effectively store and release thermal energy, showcasing high melting enthalpies, stability under thermal cycling, and lower flammability than pure diols. The first part presents the synthesis and characterization of dicationic ionic liquids (ILs), followed by the (solid + liquid) phase equilibrium, 1) + 1,6-hexanediol, 1,8-octanediol, 1,10-decanediol, or 1,12-dodecanediol (2)} systems. Eight ePCMs with enthalpies of melting varying from (190.1 to 204.5) J g −1 were determined. In the proposed systems, the bromide anion of the IL is the donor, and the hydroxyl group in the diol is the acceptor of the electron pair. The thermophysical characterization of pure ILs and the eutectic mixtures, including melting point, latent heat, as well as temperature and enthalpy of (solid + solid) phase transition, were determined by DSC analysis. Additionally, the composite systems of [(i-Quin) 2 C 6 ][2Br] and [(i-Quin) 2 C 10 ][2Br] with 1,8-octanediol and additions of single-walled carbon nanotubes (SWCNTs) and expanded graphite (EG) were prepared and characterized in terms of stability and performance. The research offers insights into the potential of these ePCMs in thermal energy storage applications, emphasizing their high latent heat and efficient thermal conductivity, especially when combined with carbon materials such as EG.

The employment of nanoparticle additives in engine oil provides an effective technique for improvement in engine performance and emission. In this study, graphene, graphene–MWCNT, and graphene–SiO2 hybrid nanoparticles have been dispersed in engine oil (n‐decane) to measure the effects of microscopic characteristics of interfacial layer between the carbon–carbon, carbon–hydrogen, carbon–oxygen, and hydrogen–oxygen molecules under fixed shear rate 600 s−1. The boundary lubrication conditions are depicted with nanoindentation operation, in which interaction between the atoms generates the molecular forces under indentation and scratching operation that provide the nucleation and propagation of dislocation in the planes. The result shows that in an early stage of nanoindentation, plastic deformation occurs in the lubricant substrate around the indenter. Furthermore, forces generated in the z‐direction have a significant effect as compared with the forces x‐ and y‐directions. Nanoindentation results concluded that for graphene–MWCNT/engine oil (n‐decane) nanoparticles, at a volume fraction of 1.8%, the nanoparticles outperformed all other nanolubricants. At a volume fraction of 0.3%, the adhesion between the solid and liquid interface was increased by 2.5% graphene nanolubricant, 4% graphene–MWCNT nanolubricant, and 8% graphene–SiO2 nanolubricant. At 1.8% volume fraction, 240% increase in graphene–MWCNT nanolubricant, 72% increase in graphene nanolubricant, and 20% increase in graphene–SiO2 nanolubricant. This trend indicates that the performance of graphene SiO2 nanolubricants is superior at low‐volume fractions, whereas the performance of graphene nanolubricants and graphene–MWCNT nanolubricants is superior at high‐volume fractions. Also we observed the scratching effect of indenter on nanolubricants.
