Thermal Conductivities and Mechanical Properties of Epoxy Resin as a Function of the Degree of Cross-linking [PDF]

arXiv, 2021
Epoxy resins are widely used polymer matrices for numerous applications. Despite substantial advances, the molecular-level knowledge-base required to exploit these materials to their full potential remains limited. A deeper comprehension of structure/property relationships in epoxy resins at the molecular level is critical to progressing these efforts.
