Abstract

Pinus kesiya and Betula alnoides wood surfaces were silylated for different times using hexamethyldisiloxane （HMDSO） plasma deposition. The wettability, element composition and their chemical bonding information, and surface morphology of the wood surfaces before and after modification were measured and analyzed using contact angle measurement, X-ray photoelectron spectroscopy （XPS）, and scanning electron microscopy （SEM）. Results showed that the hydrophobicity property of B. alnoides was better than that of P. kesiya. The contact angle increased gradually with an increase in treatment time and attained a maximum value with a 9 min treatment ［P. kesiya = （131 7.2） and B. alnoides = （138.8 1.7）］. With a 12 min treatment the contact angles decreased slightly. When deposition time was 9 min, the wood surface Si content for P. kesiya was 18.80% and for B. alnoides was 17.82%. Furthermore, the structure of the polymerization polymer films was mainly composed of SiC and SiCHx（x = 1,2,3）. After plasma coated HMDSO was applied to wood surfaces, a grain structure formed on the cell wall surface of P. kesiya; whereas a bar-like structure formed on B. alnoides. ［Ch, 8 fig. 1 tab. 19 ref.］
