Title:
ナノ多孔質ウィック及び連続気泡多孔質構造体及び製造方法
Document Type and Number:
Japanese Patent JP7356499
Kind Code:
B2
Abstract:
A nanoporous open-cell foam or wick structure and method for production are disclosed. The nanoporous foam or wick structures are produced from, for example, thermoplastic or thermoset polymer gels in which a gelation solvent is removed so as to preserve an expanded monolithic gel structure consisting of intertwined and or chemically crosslinked polymer molecular fibrils. The nanoporous foam or wick may encompass a stand-alone structure, or be incorporated in to microporous open cell foams or wick materials converting them in to nanoporous cellular materials having a bipore structure. Such produced nanoporous polymer materials have unique properties that may be exploited for making high performance capillary pump loop or heat pipe thermal management systems, low-boiloff slosh-less cryogen storage vessels and superior insulation materials for systems operating under ambient and elevated pressure conditions.
