For example, 25 vol% graphene filler in silicon foam matrix results in 6% increase of thermal conductivity [66]. The calculation for CO2 filled polyurethane of density 2.00 lb/ft3 gives 0.035 W/mK . If a polymer can be engineered with high thermal conductivity, it could find many applications in electronics, water, and the energy industry, . However, when analyze molecules elute from the column, mixed with carrier gas, thermal conductivity decreases and this causes detector response. The candidate thermoelectric compounds Mg3Sb2 and Mg3Bi2 show excellent performance near ambient temperature, enabled by an anomalously low lattice thermal conductivity (κl) comparable to those of much heavier PbTe or Bi2Te3. This strategy could be extended to other polymer composites to achieve high TE performance. Thermal insulation hinders the heat flow through conduction, convection, and radiation. The thermal conductivity dependence of bond strength: (A) effect of double bonds, (B) effect of aromatic backbone, and (C) effect of bond-strength disorder. Ganguli et al.
