中文摘要：

以禾本科植物芦苇为纤维素原料，利用纤维素在绿色溶液KOH／硫脲、尿素／水体系中的低温溶胶，高温凝胶的特性，通过化学法提取再生芦苇植物纤维素。并利用超级旋转流变仪、粘度测定仪、扫描电镜、比表面及孔径分析仪、热分析仪、傅里叶红外光谱、X射线衍射等测试手段着重研究了芦苇纤维素在该溶液体系中凝胶化再生的最佳浓度范围、以及芦苇纤维素再生前后结构和性能的变化。结果发现：芦苇纤维素溶解再生后，具有凝胶型的均匀多孔网络结构，孔容在0．77—0．62cm3·g-1，平均孔径分布在9．9～8．8nm，比表面积达到345～320m3·g-1，凝胶化再生纤维素质量浓度范围为3％-8％，结果表明芦苇纤维素化学结构再生前后没有改变，结晶度较再生前降低，并具有较再生前更好的调湿性能。

英文摘要：

Gramineous plant reed was used as cellulose raw material to prepare regenerated reed plant cellulose by extracting cellulose with chemical method and adopting properties of cellulose in green solution KOH/thiourea and urea/water system, such as sol in low temperature and gel in high temperature. Optimum concentration range of reed cellulose in solution system and structure ＆ performance change of reed before and after regeneration were emphatically studied through testing methods including super rotational rheometer, viscosity tester, scanning electron microscope, specific surface and aperture analyzer, thermal analyzer, Fourier infrared spectrum and X ray diffraction. After dissolution and regeneration of reed cellulose, it had uniform porous network structure of gel type, pore volume was distributed in 0.77 - 0.62 cm3 ~ g - 1, and the average pore-size distribution was in 9.9 - 8.8 nm. The specific surface reached 345 - 320 m3 ~ g - 1, and content range of gelatin regenerated cellulose was 3% -8%. The chemical structure of reed cellulose was the same before and after regeneration, and the crystallinity was decreased with better wet regulating performance compared with that before regeneration.
