Sustainable regenerated isotropic wood

A high-performance sustainable regenerated isotropic wood (RGI-wood) is reported, constructed from surface nanocrystallized wood particles (SNWP) by efficient bottom-up strategy. The obtained RGI-wood exceeds the limitation of the anisotropic, inconsistent mechanical properties, and inflammability of natural wood. Mass production of large-sized RGI-wood was achieved, overcoming the rareness of large-sized natural wood. Through this strategy, a series of functional RGI-wood nanocomposites can also be prepared, which show great potential in diverse applications.
