▎ 摘　　要

NOVELTY - Nanoporous body composition comprises a three-dimensional (3D) nanoporous structure in which nano-sized pores are formed, and a two-dimensional (2D) that is dispersed and positioned inside the three-dimensional nanoporous structure and improves the thermal insulation performance by reducing the nanopore size of the nanoporous structure. USE - The nanoporous body composition is used in composite insulator (claimed). ADVANTAGE - The nanoporous body composition has ultralow thermal conductivity by randomly dispersing a 2D sheet inside a 3D nanoporous structure to reduce the size of the pores, thus preventing rapid increase in thermal conductivity at high temperatures. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a composite insulator comprising a mixture of the nanoporous composition and at least one of a heat insulating mat, a glass fiber mat, and a ceramic fiber mat.
