Thermally Conductive Naphthalene Epoxy Resin by Tailoring Flexible Chain Length and Liquid Crystal Structure
Northwestern Polytechnical University · Northwestern Polytechnic University
Abstract
Abstract Epoxy resins with high thermal conductivity ( λ ) are widely used in electronic packaging, bonding, and coating. However, those with high intrinsic λ , typically synthesized using biphenyl or aromatic rings extended by ester linkages as the mesogenic unit, often exhibit high liquid crystal transition temperatures and poor processability. In this study, a series of naphthalene‐based liquid crystal epoxy monomers (LCEs) were synthesized, using naphthalene as the mesogenic unit and modifying the flexible chain length on both sides. The resulting LCEs were cured within its liquid crystal phase to form naphthalene liquid crystal epoxy resin (LCER). The results show that the network order, radius of…
