Thispaper reviewed the conventional wood composites, and then discussed the approaches to prepare woodnanocomposites. Based on the achievements of researches on polymer/montmorillonite (MMT)nanocomposites, the design ideas of preparing nanocomposites of wood and inorganic MMT weresystematically put forward. Nano compounding of wood and other materials is an effective approach togreatly improve or modify wood.展开更多

Results show that, compared with Chinese fir wood and its PF-impreg, WMNChas lower humidity and water absorption, better dimension stability, higher longitudinal compressive strength,abrasive resistance, fire-resistance, and water-leaching resistance with a very low mass ratio about 3% ofMMT. The nano intercalation compounding of wood and exfoliated MMT nanolamellae is very promising.More studies should be carried out to fully reveal the nanosize effects and the special properties of WMNC.展开更多
