The kinetics of the liquid-like → solid-like 2D phase transition of adenine adsorbed at the Hg/aqueous solution interface is studied. Attention is focused on the effect of temperature on the rate of phase change; an increase in temperature is found to cause a decrease of transition rate.

In this paper, a kind of RHA-paraffin phase change material was prepared, and the SEM was used for observing its internal morphologies, DSC analysis was carried out for detecting its temperature and enthalpy of phase transition. The results showed that rice husk ash have a greater absorption rate for paraffin; a large number of pores of the RHA were filled by paraffin in the RHA-paraffin phase change material, and the absorption rate can reach 53.5%.

A novel solid-solid phase change materials was synthesized by the two-step condensation reaction of polyethylene glycol (PEG1000), neopentyl glycol (NPG) and 4, 4-diphenylmethane diisocyanate (MDI). Polyethylene glycol (PEG1000) was used as soft segment and 4, 4-diphenylmethane diisocyanate (MDI) as hard segment. The composition, structure and phase change properties were characterized by Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), thermogravimetric analyzer (TGA), polarization optical microscopy (POM) respectively. The results indicated that the PCM appeared typical solid-solid phase transition property and the phase change enthalpy and phase transition temperature reached to 120.45 J/g and 37.32°C, respectively.
