| 摘 要： | 采用响应面法优化纳米纤维素晶须（NCW）制备工艺条件并利用傅里叶红外（FTIR）、X射线衍射（XRD）和透射电子显微镜（TEM）对NCW进行性能表征。结果表明NCW最优制备工艺条件为水解时间2．25h，硫酸浓度54％，反应温度50℃，NCW得率为75．68％，与理论预测值74．18％较吻合；模型的决定系数为98．87％，说明模型拟合有效；制备的NCW聚集态和形貌为纤维素I型，呈棒状。

| Abstract: | The preparation technological conditions of nano-cellulose whiskers(NCW) were optimized by response surface methodology and characterized with fourier transform infrared(FTIR),X-ray diffraction(XRD),and transmission electron microscopy(TEM).The results showed that optimization of NCW preparation technological conditions were 2.25 h of hydrolysis time,54% sulfuric acid concentration,and 50 ℃ of reaction temperature.Under optimization,NCW yield was 75.68%,which was identical with 74.18% of theoretical predicted values.Determination coefficient of model was 98.87%,which indicated that model fitting was effective.The state of aggregation and morphology of prepared NCW was cellulose typeⅠ and rod-like. |
