将纳米纤维素水溶液稀释至浓度千分之一,超声分散30 min,采用马尔文激光粒度仪进行测试, 在室温下进行实验,分散系为蒸馏水。采用石英比色皿进行测试。
The nanocellulose aqueous solution was diluted to one thousandth of the concentration, dispersed by ultrasound for 30 min, tested by Marvin laser particle size analyzer, and carried out at room temperature. The dispersion system was distilled water. Quartz colorimetric dishes were used for testing.
