以原位插层共聚法合成木质纤维素接枝丙烯酸/蒙脱土三维网络水凝胶(LNC-g-AA/MMT),探讨了丙烯酸与木质纤维素的质量比、丙烯酸单体浓度、中和度、引发剂用量和交联剂用量等因素对三维网络水凝胶吸附亚甲基蓝性能的影响,吸附量高达1994.38mg/g,并对最佳条件下吸附饱和的LNC-g-AA/MMT进行解吸研究,脱附率高达83.4％.用XRD、TEM和TG等方法对三维网络水凝胶的形貌和结构进行了表征.结果表明,木质纤维素接枝丙烯酸三维网络水凝胶(LNC g-AA)插层进入蒙脱土层间,蒙脱土结晶结构在反应过程中被破坏,形成剥离型纳米复合材料,LNC g-AA/MMT的热稳定性较LNC-g-AA有所改善.
