The Mn0.25Fe2.75O4-rGO/Tw80-TiO2/PEG nanocomposites have been successfully synthesized by coprecipitation, chemical reduction, and the sol-gel method. The crystal structure of Mn0.25Fe2.75O4-rGO/Tw80-TiO2/PEG nanocomposites with a variation in the composition of rGO was characterized using XRD, and information about the crystal size of 6.32 nm to 7.96 nm was obtained. These results are consistent with SAXS characterization, which indicates 2.5 nm primary particles and 6–7 nm secondary particles. The thermal properties are the highest for the MTP10 sample and the lowest for the MTP20 sample. The physical properties of these Mn0.25Fe2.75O4-rGO/Tw80-TiO2/PEG nanocomposites could be used for thermal energy storage. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2026.
