A new route for controlling the microstructure and properties of carbon aerogels via sol–gel and impregnation methods

Abstract

A new route to control the microstructure and properties of carbon aerogels via vacuum impregnation is presented. The results show that the enhanced carbon aerogels exhibit uniform pore size distribution (∼50 nm), a high compressive strength of 77.0 MPa and a low thermal conductivity of 0.15–1.62 W m⁻¹ K⁻¹ at 25 to 1600 °C.
