“…The experimental results obtained by differential scanning calorimetry demonstrated that the fabrication of the shape-stabilized phase change material of SA/ TAMSN could prevent stearic acid from leaking during the phase change process. However, the adsorption of stearic acid in the TAMSNs inhibits the activity of the stearic acid molecules, 18,37,38 and the enthalpy of SA/TAMSN would suffer a massive reduction. Additionally, with the increase of the content of stearic acid in the composite phase change material, the enthalpy of the SA/TAMSN would increase gradually.…”

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.

“…PCMs have the ability to change their state with a certain temperature range and can store and release large amounts of energy during phase change process [1][2][3]. Therefore, there are several studies on thermal properties and energy storage performance of a large number of pure and composite compounds including salt hydrates, paraffin wax and non-paraffin organic have been investigated as PCM [4][5][6][7][8][9]. Recently, microencapsulated PCM (microPCMs) technique has been developed to enlarge the utility fields of the PCMs.…”

“…As the thermal conductivity of epoxy systems is very low (about 0.2 W/(m!K)), thermally conductive fillers are added to these composites in order to dissipate the heat generated in electronic devices [6]. Various kinds of fillers, such as metals and metal oxides [7,8], aluminum nitride (AlN) [9][10][11], boron nitride (BN) [12], and silicon carbide (SiC) [13] have been applied to prepare thermally conductive polymer composites. Among them, AlN is a nontoxic, low cost substance, readily available as high purity powder.…”

Abstract.We have prepared a series of nano-sized aluminium nitride (nano-AlN)/cycloaliphatic epoxy/trimethacrylate (TMPTMA) systems and investigated their morphology, thermal conductivity, thermal stability and curing behavior. Experimental results show that the thermal conductivity of composites increases with the nano-AlN filler content, the maximum value is up to 0.47 W/(m!K). Incorporation of a small amount of the nano-AlN filler into the epoxy/TMPTMA system improves the thermal stability. For instance, the thermal degradation temperature at 5% weight loss of nano-AlN/ epoxy/TMPTMA system with only 1 wt% nano-AlN was improved by 8ºC over the neat epoxy/TMPTMA system. The effect of nano-AlN particles on the cure behavior of epoxy/TMPTMA systems was studied by dynamic differential scanning calorimetry. The results showed that the addition of silane treated nano-AlN particles does not change the curing reaction mechanism and silane treated nano-AlN particles could bring positive effect on the processing of composite since it needs shorter pre-cure time and lower pre-temperature, meanwhile the increase of glass transition temperature of the nanocomposite improves the heat resistance.
