Phase change performance of sodium acetate trihydrate with AlN nanoparticles and CMC

Solidification behavior and thermal conductivity of bulk sodium acetate trihydrate composites with thickening agents and graphite

“…Ramirez et al studied the use of CMC and silica gel to avoid phase separation of SAT and reported thermal cycling stability in cycles from 30 °C to 72 °C by use of differential scanning calorimetry (DSC) [18]. Hu et al investigated the reduction of supercooling by the use of Aluminium Nitride nanoparticles in the SAT composite with 4% CMC and found the thickening agent suitable to avoid phase separation and suspend the nucleation agent in the mixture [19]. Ryu et al investigated several salt hydrates and found that for some salt hydrates a super absorbent polymer (SAP) was an effective thickening agent however CMC was more effective for SAT [20].…”

Eutectic mixtures of sugar alcohols for thermal energy storage in the 50–90°C temperature range

“…Furthermore, it shows a large subcooling, which could be an additional drawback depending on the application [9]. Several authors have aimed to improve the thermal behavior of this material [10][11][12] and have proposed technical solutions that resulted in an enhanced stability of the PCMs. Nonetheless, the studied methods involved the modification of raw materials with additives, which could increase the PCM cost and, depending on the amount of additives, decrease the storage ability noticeably.…”

Experimental investigations on cylindrical latent heat storage units with sodium acetate trihydrate composites utilizing supercooling

“…Ryu et al investigated several thickening agent for different salt hydrates [23]. Several authors found that an SAT composite with carboxymethyl cellulose (CMC) was stable through thermal cycling [24][25][26]. Meisingset and Grønvold suggested using Xanthan rubber as a thickening agent [21].…”
