Abstract
The present disclosure relates to a high thermal conductive polymer composite, comprising: a liquid crystalline resin comprising a mesogen and at least one linear polymerization reactive group, wherein the liquid crystalline resin is cured with a linear polymerization initiator and includes a molecular structure aligned in at least one direction.
Claims11
A thermally conductive polymer composite, comprising:
- a liquid crystalline resin comprising 4,4′-diglycidyloxybiphenyl epoxy resin, and
- plate-shaped, hexagonal boron nitride impregnated within the liquid crystalline resin,
- which is cured with a linear polymerization initiator present from 0.5 weight percent to 5 weight percent, wherein the boron nitride is present in an amount of 30% to 40% by volume, and the thermal conductivity is in a range of 6.6 W/m-K 10.9 W/m-K, or
- the boron nitride is present in an amount of 40% to 50% by volume, and the thermal conductivity is in a range of 10.9 W/m-K to 17.2 W/m-K.
