چکیده انگلیسی
A cellulose nanofiber board (CNF-board) with a nominal thickness of 3â¯mm was fabricated without adhesive or additive. To provide comparison, a cellulose fiber board (CF-board) was also fabricated. A novel cold pre-press apparatus was made to dewater highly absorbent CNF gel prior to drying. A mild drying condition in the vacuum oven at 70â¯Â°C and 0.005â¯MPa was enough to provide the CNF-board with a density of 1.3â¯g/cm3 thanks to its self-densification capability. Unlike the CF-board, the fabricated CNF-board had a high water-activated dimensional recovery ratio (averagely 96%) during the five cyclic wetting-drying process. The flexural and tensile strengths of CNF-board obtained were 162â¯MPa and 85â¯MPa, respectively. The corresponding values for CF-board were 28â¯MPa and 11â¯MPa, respectively. The specific flexural and tensile strengths of CNF-board obtained were higher than those of CF-board as well as some other traditional wood-based composites, polymers and structural ASTM A36 steel.
