Material Selection and Characterization Based on Shape, Size Enhance Thermal Stability for Energy Storage Applications

The study explores phase change materials enhanced with complex dispersants, primarily aimed at improving the efficiency of TES systems. The energy storage and chemical stability of transition particles are anticipated to be highly dependent on their shape and size. The samples are characterized based on melting and solidification phases evaluated. Commercial phase change materials (0.1 wt.%) such as Al2O3, C13H11NO, C6H14O6, C6H6O2, Fe2O3, KSCN, C7H6O3, and ZnO at different pH stability (2.4-7.035) having purity 99% were dispersed in H2O and Ethylene glycol. The effect of particles in phase change materials was analyzed using TGA, FTIR, XRD, zeta potential, particle size, and FESEM for Al₂O₃ and C₆H₆O₂. The TGA enhances thermal stability with melting point temperature range from 184°C to 189.90°C mixture of Al₂O₃ and C₆H₆O₂ under weight loss conditions. The performance of zeta potential and particle size was evaluated and significantly impact their pH stability of low to medium temperature. Zeta potential is measured using methods such as concentration-based volume fraction analysis and the electrophoretic migration technique. To enhance performance the synthesis and characterization of functional materials rely significantly on determining their isoelectric point. To define functional group base hydrophobic and hydrogen bonding as their primary driving forces. For PCMs, the XRD method is utilized to analyze the atomic spacing and crystal structure in order to identify every potential plane. The spherical structure of nanophase changes particles and the required form of a rod were potential improvements for high-energy storage stability applications.
