摘要：　本研究通过微波等离子体处理木材表面,实现了木材表面与甲基丙烯酸甲酯(MMA)发生接枝共聚反应,研究了不同的反应条件对微波等离子体引发木材表面接枝MMA效果的影响。结果表明:1)接枝率随等离子体处理时间的增加而呈线性增加,但是当处理时间超过30s后呈下降的趋势;2)随着接枝反应时间的增加接枝率也增加;3)单体浓度较低有利于接枝共聚反应,浓度较高则不利于接枝共聚反应;4)经微波等离子体处理过的木材不但在室温下,甚至在更低的温度(-17℃)下也能与MMA发生接枝共聚反应,而且,接枝率随着反应温度的升高而增大;5)与催化加热法的接枝效果相比,微波等离子体法得到的接枝率更高。
By means of microwave plasma(MWP) treatment,graft copolymerization of methyl methacrylate(MMA) onto wood surface had been realized in this study.Results of MMA grafted upon wood surface by MWP initiation under different reaction conditions indicated that:1)Graft yield increased linearly with MWP treatment within 30 s,but when treatment time exceeded 30 s,graft yield decreased slowly;2)Graft yield increased with increase of graft reaction time;3)Lower monomer concentration is beneficial to graft copolymerization.On the contrary,higher monomer concentration is not beneficial to graft copolymerization reaction;4)Graft copolymerization of MMA onto wood surface can be taken place by means of MWP treatment under room temperature even under lower temperature(-17 ℃).Furthermore,graft yield increased with reaction temperature;5)Compared with the method of heatcatalysis initiation,graft yield by MWP initiation is higher than that of heatcatalysis method.
