摘　　要：采用空气介质阻挡放电(DBD)冷离子体处理云南松木材表面,分析了不同处理时间和处理功率对云南松表面润湿性的影响。试验结果表明:云南松表面经空气DBD冷等离子体处理后,表面接触角显著减小,表面能明显增大,表面润湿性得到明显改善。实验中最优的处理工艺为:处理功率为4 kW,处理次数为7次(处理速度为12 m/min)。The surface of Pinus yunnanensis wood was treated by air dielectric barrier discharge（DBD） cold plasma.The influence of treatment time and power on the wettability of the treated wood was investigated.The results showed that the treatment resulted in lower contact angle and higher surface free energy of the sample,meaning increased hydrophilicity.The optimal treatment result was achieved when the samples were treated 7 times with a treatment power of 4 kW and treatment speed of 12 m/min.
