Abstract:Three-dimensionally connected, pore-adjustable, high-porosity
Al2O3 foam (AF) and graphite in situ modified
Al2O3 foams (GAFs) were prepared by using the
particle-stabilized
emulsion as a template. A graphite layer was coated on the surface
of Al2O3 particles by using sucrose as a carbon
resource, preventing PEG leakage and improving the thermal conductivity.
After encapsulating PEG with AF and GAF, we obtained a series of stabilized
composite phase change materials (sPCMs). The melting enthalpy of
PGAF can re… Show more
