中文摘要：

细菌纤维素经过LiCl／DMAc体系溶解再生后可溶于碱溶剂体系NaOH／尿素／硫脲混合液中．本实验研究了再生细菌纤维素在NaOH／尿素／硫脲溶剂体系中的溶解机理以及NaOH、尿素、硫脲的浓度对溶解性能的影响，从而得到该体系下的最佳溶解条件：NaOH质量分数7％，尿素质量分数8％，硫脲质量分数10％，预冷温度在-10℃以下．

英文摘要：

Regenerated bacterial cellulose received from the dissolution of BC in LiCI/DMAc and the coagulation from distilled water can be dissolved in NaOH/urea/thiourea aqueous solution. The dissolution mechanism of RBC in NaOH/ urea/ thiourea aqueous solution and the influences of different concentration of NaOH, urea and thiourea are studied. Then the best dissolving conditions of RBC are concluded as 7% NaOH, 8% urea, 10% thiourea aqueous solution precooled below to -10℃.
