“…As a consequence of the increased energy absorption and emission capabilities of the PCM, the building envelope can be made thinner and lighter. The Cp (specific heat capacity) also needs to be high [ 60 ]. There can be no thermodynamics without efficient heat transmission.…”

“…The studies concluded that the PCM emulsion with mixed surfactant (Sodium dodecyl sulfate and Brij30) can be a potential heat transfer medium with improved heat storage and transportation capacity. Sheikh et al, [7] enhanced the thermal stability of nano-PCM composite by employed the sodium dodecyl sulfate (SDS), sodium dodecyl benzenesulfonate (SDBS), and sodium stearoyl lactylate (SSL) as the surfactants. In addition, the surfactants also used to measure the thermal characteristics in terms of indices such as thermal conductivity, thermal capacity, and time of reaching the reference temperature.…”

The use of nano phase change material (PCM) as a heat transfer agent has spread and expanded as its thermal conductivity is higher than the base PCM, so its use has been increased in PVT systems. In this study, inorganic salt hydrated PCM was used as a base material and Graphene nanoplatelet (GNP) as an additive to improve the thermal conductivity of the resulted nano-PCM and its stability was studied using Cetyl Trimethyl Ammonium Bromide (CTAB) surfactants. The main objective of the present study was to investigate the effect of surfactant on the stability of different GNP concentration in CaCl2.6H2O PCM. The nano-PCM has been prepared using two-step method. The stability of nano-PCM depends on the surfactant used to slow the sedimentation of nanoparticles in the base PCM. The sedimentation process significantly reduces the thermal conductivity of nano-PCM and thus reduces heat transfer. The study results indicated that the employment of surfactant significantly affected the stability of nanoparticles added in the base PCM. The stability test ascertained the effectiveness of the surfactant applied in phase change material. With successive addition of surfactant, the stability of GNP in PCM was further enhanced to +49.3 mV of Zeta potential value.

“…However, their effectiveness depends on the climatic conditions and the melting temperatures of the PCMs [18]. Phase change materials can be blended with conductive nanomaterials [19] to improve their cooling and stability characteristics. There is an enhancement of latent heat and heat storage efficiency with the addition of 0.3% nanoparticles [20].…”

This study addresses the global plastic waste crisis and the urban heat island effect by developing an innovative solution: recycled plastic roof tiles embedded with phase change material (PCM) and coated with hollow-glass-microsphere-based white paint. The samples were fabricated with cow pie fibers, OM37 and OM42 PCM materials with different wt./vol. values, i.e., 15/50, 20/50, 25/50, 30/50 ratios. The fabricated tiles were coated with hollow glass microspheres to provide a reflective layer. The tiles’ effectiveness was evaluated through morphological examination and thermal analysis. The SEM analysis revealed an excellent bonding ability for the PCM blend, i.e., OM37 and OM42 at a 20/50 ratio (wt./vol.) with cow pie fibers. Adding cow pie fibers to the PCM shifted the melting points of OM37 and OM42, indicating an increased heat storage capacity in both blends. The thermal conductivity results revealed decreased thermal conductivity with an increased cow pie fiber percentage. The recycled plastic roof tile of the PCM composite at a 20/50 (wt./vol.) ratio showed good thermal properties. Upon testing in real-time conditions in a physical setup, the roof tiles showed a temperature reduction of 8 °C from outdoors to indoors during the peak of summer. In winter, cozy temperatures were maintained indoors due to the heat regulation from the roof.
