摘要
With montmorillonite (MMT) organically modified as organophilic-MMT (OMMT) and water-soluble phenol formaldehyde resin (PF) as intermediate, the nanocomposites of Chinese fir (Cunninghamialanceolata) wood and MMT, i.e. WMNC, were prepared via nano intercalation compounding, some propertiesof WMNC were analyzed. 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.
