| Outline of Final Research Achievements |
Both epoxy / polyethersulfone blends with reaction-induced phase separation mechanism (scale of the phase structure: micrometers) and self-assembly nanostructured epoxy / block copolymer blends (scale of the phase structure: a few tens of nanometers) were applied as the matrices of epoxy / silver filler (Ag) composites. In the blends with the reaction-induced phase separation, the connected Ag fillers were selectively located in the epoxy-rich continuous matrices. The composite structures gave high electrical and thermal conductivity, and high adhesive strengths using a relatively small amount of the Ag fillers. In the self-assembly nanostructured epoxy blends also, Ag nano-fillers were selectively located in the epoxy continuous phases which had high affinity to the Ag fillers than the elastomer phases of the block copolymers.
