“…Additionally, the low thermal conductivity of fatty acids poses a challenge for their applications. In order to solve this problem, the additives with high thermal conductivity, including expanded graphite [14,15], carbon nanotubes [16,17] and silica fume [18], have been introduced to enhance the thermal conductivity of form-stable composites.…”

“…28 These above peaks were all typical for chains of stearic acid, and also appeared in the spectrum of the composite material. In view of these patterns, it could be demonstrated that stearic acid was successfully adsorbed on the mesopores of the TAMSNs by physical adsorption.…”

Tannic-acid-templated mesoporous silica nanoparticles (TAMSNs), which were synthesized using a simple, environmentally friendly, cost-effective, and nonsurfactant-based template method, were developed as a matrix for stearic acid to fabricate a novel shape-stabilized phase change material (SA/TAMSN). The characterization results showed that stearic acid was fully adsorbed on the TAMSNs by physical adsorption and the TAMSNs had no effect on the crystal structure of stearic acid. According to the DSC results, although the TAMSNs had a confinement effect on the activity of the stearic acid molecules, the fusion and solidification enthalpies of SA/TAMSN could reach 108.8 J g À1 and 114.1 J g À1, respectively.Additionally, the TGA thermograms indicated that there was no apparent weight loss from 20 C to 223 C for SA/TAMSN, which demonstrated that SA/TAMSNs have excellent thermal stability. All of the results suggested that the TAMSNs could be used as a promising matrix candidate for the shape stabilization of stearic acid.

“…The results showed that the porosity and thermal conductivity of the matrix composite played important roles in the thermal performance of the device. In another study, a form-stable PCM prepared by impregnating SA into a silica fume matrix using a solution impregnation technique was investigated [118]. The results show that the form-stable composite PCM has the optimal effect, preventing the leakage of SA from the composite, which emerged when the SA and silica fume mass ratio is 1:0.9.…”

This paper presents the principal methods available for phase change material (PCM) implementation in different storage applications. The first part is devoted to a non-exhaustive overview of the various chemical processes used to develop stable PCM (such as microencapsulation, emulsion polymerization or suspension polycondensation, polyaddition, etc.) based on the available literature. The second part deals with shape-stabilized PCM, developed from an intimate combination of a polymer matrix and a phase change element. Materials able to include more thermal energy as usual ones are interesting as they increase the thermal inertia of the system that presents by this way advantages. The energy efficiency of buildings may be improved including PCMs that store and provide enthalpy from one hand and without any significant temperature modification during the phase change process on the other hand. If the solid phase of the PCM does not present any problem, it is not the same for the liquid phase which must be maintained mechanically at its assigned location. Furthermore, the PCM in the solid (and furthermore in the liquid phase) does not have mechanical properties which allow to use it as a structural material able to support charge loads. This paper presents different methods to distribute and maintain the PCM in the thermal solid matrix.
