Another wood processing advancement from the same team that developed the bulletproof Super Wood.

Anisotropic, lightweight, strong, and super thermally insulating nanowood with naturally aligned nanocellulose


"We also performed a materials cost analysis to fabricate the nanowood, including raw materials and processing chemicals (table S1), which can be as low as $7.44/m2. The nanowood can be processed into different shapes and sizes, suitable for versatile applications that require thermal insulation, ranging from steam and chemical pipes to building applications."

"Hu and his team have already developed a strong, dense material they called super wood, in part by removing some of the wood’s lignin – a complex polymer that holds cellulose in the wood together, almost like glue – and hemicellulose, another component of woody tissue.

But for this project, Hu and his colleagues removed all of the lignin and most of the hemicellulose. Lignin is very good at conducting heat – which means it would be a terrible insulator. Without all that lignin, the woody material turned pure white, allowing it to reflect incoming light rather than absorb it (which also helps to block heat)."
