...When our founder,
Dr. Liangbing Hu, published his groundbreaking SUPERWOOD process
in the prestigious journal Nature in 2018, it marked the
beginning of the next major leap forward in the fundamental
materials that humanity builds with, a marriage of nature and
technology that rises to the needs of today and tomorrow.   
  
Today, after seven
years of intense development work, substantial investment, and
over 140 patents, SUPERWOOD is ready to reshape how we build our
world. This isn't just innovationait's transformation.

Simple processes can
make wood tough, impact-resistantaor even transparent    
...Hu and his
colleagues say they have come up with a better way to densify
wood, which theyreport in the February 7 Nature. Their simple,
two-step process starts with boiling wood in a solution of
sodium hydroxide (NaOH) and sodium sulfite (Na2SO3), a chemical
treatment similar to the first step in creating the wood pulp
used to make paper. This partially removes lignin and
hemicellulose (natural polymers that help stiffen a plantas cell
walls)abut it largely leaves the woodas cellulose (another
natural polymer) intact, Hu says...  
The results are
impressive. The teamas compressed wood is three times as dense
as the untreated substance, Hu says, adding that its resistance
to being ripped apart is increased more than 10-fold. It also
can become about 50 times more resistant to compression and
almost 20 times as stiff. The densified wood is also
substantially harder, more scratch-resistant and more
impact-resistant. It can be molded into almost any shape.
Perhaps most importantly, the densified wood is also
moisture-resistant: In lab tests, compressed samples exposed to
extreme humidity for more than five days swelled less than 10
percentaand in subsequent tests, Hu says, a simple coat of paint
eliminated that swelling entirely.
