中文摘要：

采用微波等离子体（MWP）对竹材进行了表面处理，测定了处理前后甘油和脲醛树脂胶在其表面的接触角，以此评价竹材表面改性的效果。结果表明：随MWP处理时间延长和试件距反应腔距离减小，竹材表面接触角呈降低趋势；竹材试件距反应腔距离40mm时，用甘油作测试液体在接触15s时测试，MWP处理30s即可将竹材表面接触角降低49％～59％；甘油所测竹材表面接触角较脲醛树脂胶所测值低，测试液滴到样品上15s所测竹材表面接触角较5s时低；在经等离子体处理后，砂光与否对竹材的表面性能影响不大，砂光后再经等离子体处理，比直接进行等离子体所得到的改性效果稍好。

英文摘要：

The surface treatment of bamboo timber was carried out by microwave plasma （MWP）. The surface contact angle of samples was measured by using glycerin and UFR. Hence the influence on the surface performance of bamboo sample was evaluated. The results showed that the surface contact angle of samples became the decreasing trend as a whole with prolonging the MWP treat time and the distances shorting between the sample and resonance cavity. The surface contact angle of sample descend 49%-59% with MWP treating 30 s, when the distances between the sample and resonance cavity were 40 mm and measured at 15 s after dripping with glycerin. The surface contact angle of samples was lower measured with the glycerin than t＇hat of UFR, also at 15 s after dripping than that of 5 s after dripping whether it was glycerin or UFR. The grinding treatment had a little effect on the surface contact angle of samples after MWP treatment. The modification effect was better treated by MWP treating after grinding than that of treating by MWP directly.
