Microstructure-free strong all-wooden nanocomposites (AWNC) was directly made from the weak raw wood (RW) of paulownia, in which microscale wood fibers and void structures were dismantled into a fully consolidated structure containing nanofibrils (as the reinforcing phase) and noncrystalline cellulose, lignin, and hemicelluloses (as the matrix phase). This direct conversion was carried out through simultaneous chemomechanical densification/downsizing in three steps, including (1) partial delignification, (2) partial dissolution with IL or oxidation with TEMPO and ammonium persulfate (APS), and (3) hot pressing with cyclic pressurizing-depressurizing conditions.
