摘要/Abstract

摘要： 用氧等离子体处理酶解木质素，分析酶解木质素表面化学成分及自由基浓度的变化，研究氧等离子体处理对酶解木质素/杨木纤维复合材料性能的影响，探索氧等离子体对酶解木质素胶合力的影响。结果表明：经氧等离子体处理后，酶解木质素表面m(O)/m(C)提高了56.0 %，大量含氧官能团（如—OH、—COO等）被引入酶解木质素表面。同时，酶解木质素表面自由基浓度提高了27.4 %。氧等离子体处理使酶解木质素/杨木纤维复合材料的物理力学性能得到了改善，其中内结合强度提高了30.2 %，静曲强度增加了14.2 %，吸水厚度膨胀率下降了29.0 %。

Abstract: This paper investigates the effect of oxygen plasma treatment on bonding behavior of enzymatic hydrolysis lignin (EHL) obtained from the lignocellulosic ethanol production processes. To understand the effects of oxygen plasma treatment, the changes of chemical compositions and free radicals of EHL surface were analyzed. The physical and mechanical properties of poplar fiberboards with EHL as a natural binder were tested as well. The results showed that adding oxygen plasma treated EHL produced a 30.2 % increase of internal bond strength (IB), a 14.2 % increase of modulus of rupture (MOR), and a 29.0 % reduction of thickness swelling (TS). The bonding improvement was probably due to the generation of more oxygenrelated functional groups (such as —OH，—COO) and free radicals on the surface of EHL after the oxygen plasma treatment.
