摘　　要：采用一种操作简单、绿色环保的以对甲苯磺酸为催化剂对竹纤维进行水热处理制备纳米纤维素(NCC)的方法。考察了反应时间、反应温度和超声作用对纳米纤维素得率和性能的影响。结果表明,在反应温度110℃、反应时间45 min、超声时间120 min的条件下,纳米纤维素得率最高。A kind of simple and environmentally friendly method for preparing nanocellulose(NCC)by hydrothermal treatment with p-toluenesulfonic acid as catalyst was introduced.The effects of reaction time,temperature and ultrasound on the yield and prop-erties of nanocellulose were investigated.The results showed that the highest yield of nanocellulose was obtained at reaction tempera-ture of 110℃,reaction time of 45 min,and ultrasonic time of 120 min.
