中文摘要： 高得率制浆技术能有效地利用有限的森林资源，降低成本，减少污染，是当今制浆造纸工业发展的重要趋势，其中APMP技术是最有前景的高得率制浆方法之一。但APMP浆的柔韧性低，纤维间的结合差，影响了其在高档纸中的应用。因此，对APMP浆进行改性，提高其物理性能从而满足多种纸张的需要有重要意义。本研究以桉木APMP浆为研究对象，利用环境友好，对纤维无损伤的低温等离子体对其进行改性处理，以达到增强纤维之间结合力的目的。研究重点探讨了其最佳改性工艺，并应用改性后桉木APMP浆配抄新闻纸。同时，利用SEM、AFM、CLSM、XPS、ToF-SIMS等现代仪器分析低温等离子体表面改性的机理，重点分析低温等离子体改性前后桉木APMP浆纤维形态及纤维表面化学特性的变化情况，初步建立起桉木APMP浆纤维表面低温等离子改性理论，为进一步扩大机械浆的应用领域提供依据。

英文摘要： High yield pulping technology can effectively utilize the limited wood raw materials. It is one of the important trends of the development of pulp and paper industry. The APMP technology is one of the most promising high yield pulping method. However, the low flexibility and the fiber bonding of APMP affect the application in high-grade paper. Therefore, it is important to modified APMP and enhanced its physical properties to meet a variety of paper needs. APMP process of Eucalyptus wood was studied. Eucalyptus APMP was modified via low temperature plasma technology which is environmentally friendly, low energy consumption and no damage to fiber. The optimal modified process was studied to improve the quality of fiber. Modified Eucalyptus APMP manufactures the newsprint. The effects of plasma treatment on the fiber surface properties and paper physical properties were investigated with SEM, AFM, CLSM, XPS and ToF-SIMS. The fundamental mechanism of plasma modified pulp fiber was explored to provide a theoretical basis and technological support for the use of plasma in pulp and paper industry.
