摘要

The cost and availability of wood as made it a widely utilized material in many applications,rnhowever their inherent hydrophilic nature has limited their intrusion into other markets. AtrnWashington State University we have developed a low-cost plasma operation that appliesrna polymer deposit on the surface of wood to alter the hydrophilic nature, including waterrndiffusion. By using an atmospheric pressure weakly ionized plasma reactor wood veneersrnand particles were coated with nano-sized polymerized deposits on the wood cell surface.rnResults from contact angle and capillary rise tests showed a significant drop in waterrnsorption of all wood substrates. The potential for this environmentally benign processingrnmethod lies not only in increasing the moisture performance and durability of WPCs, butrnalso potentially enhancing the compatibility between wood and thermoplastic polymers.rnRecent work has also shown that an increase in deposition rate with modification to thernreactor design providing more incentive for a potential commercial process.
