Abstract Inorganic hydrated salts, noted for their high thermal storage density, excellent conductivity, and non‐toxicity, are suitable candidate material management, particularly in enhancing human living environments when phase transition points near room temperature. Herein, we present an efficient environmentally friendly microencapsulation method inorganic salt through organic separation method. Eutectic (EHS) consisted of sodium carbonate decahydrate (SCD) disodium hydrogen phosphate dodecahydrate (DHPD) was prepared as the core while mixture ethyl cellulose (EC) acrylonitrile‐butadiene‐styrene (ABS) composite shell materials. Various characterization techniques were used to evaluate micromorphology, chemical structure, properties stability microcapsules. The resulting microcapsules exhibited a change temperature 22.6 °C with remarkable enthalpy 131.4 J/g. Particularly, remained at 117.7 J/g even after 50 cycles, indicating stable cycling reliability. Furthermore, it confirmed that EHS effectively encapsulated within shell, had quasi‐spherical shape core‐shell structure. More importantly, this could potentially be extended other liquid salts temperature, offering versatile approach future applications.

To meet the requirements of both high thermal conductivity and substantial latent heat storage release in spacecraft management materials, this study employs a hot-pressing technique to fabricate multidimensional carbon-based, thermally enhanced microencapsulated phase change composite. This approach addresses limitations conventional which exhibit low propensity for liquid leakage. By integrating experimental assessments with finite element numerical simulations, we systematically investigated effects varying contents ratios flake graphite, pitch-based carbon fibers on composite’s properties, specifically heat.
