How does curing induced phase separation control the carbon black nanostructuring which enhances its epoxy-based nanocomposite conductivity?

In this research work, the role of MBS core-shell nanoparticles in carbon black (CB) nano structuringby curing induced phase separation of epoxy resin with DDS cross-linker was investigated by DMTA,electrical conductivity, and scanning electron microscopy (SEM). The conductivity of cured epoxywas enhanced from ۱۰-۱۳ to ۱.۴۸ ۱۰-۵ siemens/cm by crossing the threshold carbon black overlappingof ۷ wt. % complementing ۳ wt. % of MBS inclusion. On the other hand, the estimation of systemsurface and interfacial interactions along with the DMTA and SEM results confirmed the formationof a pervasive network representing simultaneous conductivity/toughening enhancement of theresulting hybrid nanocomposite.
