Effect of high-temperature-resistant epoxy resin/polyethylene glycol 2000 composite stereotyped phase change material particles on asphalt properties

Study on Miscibility, Thermomechanical Behavior, and Thermoregulation Performance of Paraffin Wax/Bituminous Blends for Solar Thermal Energy Storage Applications

“…From a performance point of view, it is noteworthy that all binders present high thermal stability since their initial decomposition temperatures are clearly higher than the specific temperature range for low-temperature solar energy collection (40–80 °C), , even allowing them to be used at the high temperatures required in the asphalt paving industry …”

“…From a performance point of view, it is noteworthy that all binders present high thermal stability since their initial decomposition temperatures are clearly higher than the specific temperature range for low-temperature solar energy collection (40−80 °C), 26,35 even allowing them to be used at the high temperatures required in the asphalt paving industry. 36 A common bitumen characterization parameter that provides valuable structural information for the high-temperature performance of the bituminous binders is the ring-andball softening temperature. Figure 8 shows the evolution of this parameter with the paraffin wax concentration.…”

“…60 °C due to the heat absorption process occurring during the phase change. Interestingly, the BP40 blend presents higher specific heat capacities than base bitumen in the whole testing temperature window, especially between 40 and 60 °C, the range in which the thermoregulation effect for solar energy heating applications is considered . In addition to that, the BP40 blend shows higher thermal conductivities than base bitumen, a fact that reduces the time for the heat charging/discharging processes and, thereby, enhances the efficiency of the thermal energy storage.…”

Water-resistant gum-based phase change composite for thermo-regulating insulation packaging

“…Moreover, the measured phase change properties before and after the cycling test are tabulated in Table 4. It is obvious that the phase transition enthalpy did not show a noticeable change after heat treatment at 80 • C, indicating there was no leakage or loss of the PCM [63]. In other words, PEG was effectively kept in the porous structure of the GT matrix.…”
