HydrogelThermal conductivityDamagePercolation theoryThe thermal conductivity of polymeric materials is greatly influenced by the morphology of the internal molecular networks. Specifically, the irreversible alteration of molecular networks through external stress or damage changes the thermal conductivity of ...
Liquid bridge: liquid metal bridging spherical BN largely enhances the thermal conductivity and mechanical properties of thermal interface materials. J Mater Chem C, 2022, 10: 6736–6743 Article Google Scholar Jia X, Liu B, Li S, et al. High-performance non-silicone thermal interface materials...
Improving thermal insulation is vital for addressing thermal protection and energy efficiency challenges. Though silica aerogel has a record-low thermal conductivity at ambient pressure, its high production cost, due to its nanoscale porous structure, ha
where Cp and K are the effective heat capacity and effective thermal conductivity of the cavity material, respectively. I represents the optical power that actually heats the cavity, and δλ is the mode linewidth of the cold cavity. The first term of Eq. (2) represents the heat generated ...

This phenomenon is probably induced by the low thermal conductivity of air trapped in the mesh topological structure of PVA-CS hydrogel (0.026 W m−1 K−1) [34]. Overall, such a high thermal conductivity of FBP can effectively transfer heat from the scald tissues up to the evaporation ...
We further modeled the application value of wood-based thermoelectric sponges in smart buildings for power generation. Relatively high thermoelectric electricity can be obtained, such as in Beijing with over 1.5 million kWh every year, demonstrating the great potential in thermal energy harvest and ...
Effective thermal safety management relies on the thermal conductivity of interlayer materials, yet current designs lack the needed responsiveness for both performance and safety. Here we design a thermal-switching material with high switching ratio from thermal conduction to thermal insulation state to ad...
of hydrogels at the nano-scale and deflections of micro-cracks at the interfaces, which avoid stress concentration and dissipate huge energy. Furthermore, this cement-hydrogel composite also exhibits a low thermal conductivity (around 1/10 of normal cement) and density, high specific strength and ...
A gel with low thermal conductivity can maintain a high-temperature difference between the electrodes, and the reduction of the temperature gradient will also reduce the thermogalvanic potential. Reaction kinetics is used to explain conductivity; the reaction resistance of redox substances at the ...
