Abstract

Epoxy resins (epoxy), also known as polyepoxides, are an extensive class of reactive polymers containing epoxide groups, and a very popular material is used in various applications such as marine, automotive, aircraft and aerospace architectures and electronic applications. However, epoxy is brittle and has high coefficient of thermal expansion, poor mechanical strength and electrical conductivity. Incorporating nano and micro filler in epoxy is an established approach to enhance all these properties. However, obviously also depends on the properties of the filler. In this mini review article, we will briefly describe how carbon nanomaterials, depending on their intrinsic structure and properties, can affect the epoxy composite foams, in terms of their fabrication methods, resulting mechanical, dielectric, and physical properties.
