Hydrophobization of wood surfaces: covalent grafting of silicone polymers
2001
Sebe, G. | Brook, M.A.
The hydrophilicity of Maritime pine wood surfaces was modified by silicone, an extremely hydrophobic material. A generic method for the introduction of a variety of silicones at the surface of pre-treated wood was developed. The initial treatment of wood with maleic anhydride and allyl glycidyl ether resulted in oligoesterified wood bearing terminal alkenes. The hydrosilylation of these groups, performed with hydride-terminated silicones, led to very hydrophobic surfaces, even after extensive soxhlet extraction with good solvents for silicones. The presence of silicon, only at the surface of hydrosilyated wood, was confirmed by ESCA. The silicones appear to be attached to the wood by covalent bonds.
