Nanoporous super thermal insulation material is a new type thermal insulation material with light
weight, high temperature resistance, high porosity and low thermal conductivity. Based on these advantages, it has
become a research hotspot in the field. The most representative nanoporous super thermal insulation materials are aerogel
thermal insulation material and nanopowder based thermal insulating composites. In this paper the research status
of nanoporous thermal insulation material is summarized and the development prospect is shown.
