摘      要：Polymer based nanocomposites consisting of elastic three-dimensional(3 D)carbon foam(CF),paraffin wax and graphene nanoplatelets(GNPs)have been created and evaluated for thermal energy *** ultralight,highly porous(~98.6%porosity),and flexible CFs with densities of2.84-5.26 mg/cm^3 have been used as the backbone skeleton to accommodate phase change wax and nanoscale thermal conductive enhancer,*** level of defects and the ordered sp2 configuration allow the resulting CFs to exhibit excellent cyclic compressive behavior at strains up to 95%,while retaining part of their elastic properties even after 100 cycles of *** dispersing the highly conductive GNP nanofillers in paraffin wax and infiltrating them into the flexible CFs,the resultant nanocomposites were observed to possess enhanced overall thermal conductivity up to 0.76 W/(m K),representing an impressive improvement of226%,which is highly desirable for thermal engineering.
