Abstract : Block copolymers (BCPs) are considered a new class of material that is capable of enhancing the toughness of epoxy to a greater extent. The microphase separation followed by self-assembly allows them to form micellar nanostructures in the epoxy matrix, which leads to enhanced toughness of the epoxy. Depending on the concentration, these BCPs can self-assemble into wormlike, spherical, and vesicle nanostructures as well as conduct reaction-induced microphase separation. But it negatively affects other inherent properties such as tensile strength and glass transition temperature; hence, utilizing BCPs along with other nanomaterials can effectively avoid the limitations. Further, the incorporation of BCPs helps in enhancing the potential of epoxy in different applications such as coating, electromagnetic interference shielding, flame retardancy, etc. This chapter gives an insight into the recent development of BCP-based epoxy toughening and its potential engineering applications.
