The new method provides aerogels that are both strong (yield strengths >1.2 MPa) and has low thermal conductivities in both radial direction (0.037 W/mK) and axial direction (0.057 W/mK), which is rare.
“Biobased strong aerogels could be used to replace current fossil-based aerogels for super thermal insulation, contributing to energy efficiency, bioeconomy, and sustainable society development,” says Assistant professor Yuanyuan Li to kth.se.
The research was recently published in ACS Applied Materials & Interfaces.
