Outline of Final Research Achievements

Elastomeric foams are expected to be used as insulation, sound insulation, low dielectric and lightweight components, but there is no high-density foam with a hierarchical structure that can fully demonstrate these functions. In this study, we developed an elastomer controlled the length between the crosslinking points of interpenetrating polymer with two kinds of crosslinking end groups introduced, and examined improvement of foaming density. Batch foaming using supercritical carbon dioxide was carried out and nanopores were made by controlling the crosslinking density, but the number density of bubbles improved only about 50 times compared with untreated elastomer and was insufficient. On the other hand, we prepared a nanocomposite material incorporating highly anisotropic nanofiller components, but nano-foams could not be produced in the period of study. We will continue to study foaming method that will improve bubble number density.
