Surface Performance and Moisture Adsorption of Wood Fiber Modified with Montmorillonite
Sodium-montmorillonite(Na-MMT)and quaternary ammonium salt(DDAC)were sequentially used to modify wood fibersto improve dimensional stability of MDF.The moisture adsorption and contact angles of the modified fibers were investigated and the fiber structure, surface groups and morphology were also characterized.The results showed that the moisture absorption rate of the fibers decreased and the contact angles increased after modification.Organic montmorillonitewas formed through reactions between Na-MMT and DDAC and then was intercalated into the cell wall and was further reacted with chemical components of the fibers.
