TL;DR: In this article, the enthalpy change of phase change materials (PCMs) is measured with high precision using differential scanning calorimetry (DSC) and T-history method.
Abstract: Phase change materials (PCMs) are thermal storage materials with a high storage density for small temperature range applications. In the design of latent heat storage systems, the enthalpy change of the PCM has to be known as a function of temperature with high precision. During dynamic measurements, the sample is not in thermal equilibrium, and therefore the measured value is not the equilibrium value. The influence of non-equilibrium on the measurement results can be quantified by doing measurements during heating and cooling with any measurement instrument. Measurements carried out by differential scanning calorimetry (DSC) and by the T-history method are presented and discussed. To characterize encapsulated PCM objects, measurements on the whole objects should be carried out. A measurement setup for this purpose is also presented. The obtained precision meets typical application requirements, and good agreement between results obtained with the different methods is demonstrated.

TL;DR: The C-O-C stretching bands of infrared spectra were found to shift toward higher wavenumbers with sol-gel transition, indicating that hydrogen bonding is not the driving force for gelation, and a mechanism of gelation based on micelles packing and entanglements is suggested.
