Wood-based aerogels prove better insulation properties than fossil-based materials

A new method for the creating of insulating nanostructures in the pores of wood-based aerogels developed by WWSC researchers gives materials with better insulation than conventional fossil-based insulation materials.

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.
