采用N2、O2两种等离子体气体分别处理木材,处理功率为300 W,处理时间为5min,将处理后的木材采用MUF胶粘合起来,测试了胶合强度,对冷等离子体处理前后的木材表面接触角、表面能能进行分析;并采用x-射线光电子能谱对处理前后木材表面的化学成分进行了分析。实验结果表明:经N2、O2冷等离子体处理后的木材表面的接触角明显减小,表面自由能明显增大;经冷等离子体处理后的胶合板的平均干状胶合强度和湿状强度均有明显(50%以上)增大;XPS的分析结果表明,经N2冷等离子体处理后,木材表面的氧/碳原子浓度比增加,产生了大量含氧官能团或过氧化物,同时引入了N元素,推测有-NH2生成。 Two kinds of plasma gases, N2 and O2, were used to treat the wood respectively. The power was 300 W and the treatment time was 5 min. The treated wood was glued with MUF glue to test the bonding strength. The wood surface before and after cold plasma treatment Contact angle, surface energy can be analyzed; and the chemical composition of the wood surface before and after treatment was analyzed by x-ray photoelectron spectroscopy. The experimental results show that the contact angle of the wood treated with N2 and O2 cold plasma decreases obviously and the surface free energy increases obviously. The average dry gluten strength and wet strength of the plywood treated with cold plasma have (50%) increased obviously. The results of XPS analysis showed that after the N2 cold plasma treatment, the concentration ratio of oxygen to carbon in the surface of the wood increased, resulting in a large amount of oxygen-containing functional groups or peroxides, and at the same time N element , Presumably -NH2 generation.
