Abstract: There are provided a compound having a thermotropic liquid crystalline structure and a polyethylene glycol polymer. The compound is obtained by modifying an epoxide functional group in a thermotropic liquid crystalline molecule. The polyethylene glycol polymer is obtained by ring-opening polymerization thereof. The polyethylene glycol main chain polymer is easy to form in thin film, bulk, or fiber form, and has a high thermal conductivity and thus can be used alone or in the form of a composite material as a heat-dissipating polymer.
