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

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 (similar to 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 degrees C.

Automated summary

This study presents a new method of controlling the microstructure and properties of carbon aerogels through vacuum impregnation. The enhanced carbon aerogels exhibit uniform pore size distribution, high compressive strength, and low thermal conductivity.
