Abstract

We synthesized twin-mesogen epoxy polymer in which there were two 2,7-naphthalene benzoate as mesogens connected by four carbons alkyl chain and investigated the effects of higher-order structure changes due to the differences of alkyl chain length and mesogen groups on thermal conductivities. This polymer is abbreviated as TME2,7-NB4. NB means naphthalene benzoate and 4 means spacing carbon number. As a result, the thermal conductivity of TME2,7-NB4 was higher than that of TME2,7-NB8, but the coherent length D was less than that of TME2,7-NB8.
