Biomass Homogeneity Reinforced Carbon Aerogels Derived Functional Phase?Change Materials for Solar–Thermal Energy Conversion and Storage

We devised a functional form stable composite phase-change materials (PCMs) to achieve three-dimensional (3D) interconnected porous carbon aerogel structure for encapsulating polyethylene glycol (PEG). A novel homogeneity reinforced with well-interconnected was constructed by combining flexible resource from biomass guar gum hard-brittle polyimide, overcome severe shrinkage and poor mechanical performance of traditional aerogel. The supporting aerogel-encapsulated PEG produced the PCMs good stability comprehensive energy storage performance. results showed that displayed well-defined 3D structure, their capacities were 171.5 169.5 J/g, which changed only slightly after 100 thermal cycles, composites could maintain equilibrium temperature at 50.0?58.1 °C about 760.3 s. conductivity reach 0.62 W m?1 K?1, effectively enhanced response rate. And exhibited leakage-proof excellent light–thermal conversion. compressive strength can improve up 1.602 MPa. Results indicate this strategy be efficiently used develop improved high
