摘要:

以八元瓜环、膨润土为双交联剂制备了力学性能可控的羧甲基纤维素/丙烯酸/八元瓜环/膨润土水凝胶(CMC/AA/CB[8]/BET gel)。采用FT-IR、SEM技术表征其结构和形貌,研究了这种凝胶的力学性能和吸附性能以及溶胀和吸附动力学。结果表明：CB[8]和BET通过氢键与接枝到CMC上的AA形成致密的网络结构,使凝胶的力学性能增强；这种凝胶的溶胀符合准二级动力学模型,并与应力松弛溶胀半结晶聚合物理论相符；这种凝胶在酸中浸泡后酸中的游离H⁺与CB[8]、BET生成的氢键使凝胶的断裂强度从0.52 MPa显著提高到3.0 MPa；这种凝胶对亚甲基蓝有良好的吸附效果,符合准二级动力学模型。

Abstract：

Hydrogel of (CMC/AA/CB[8]/BET gel) with controllable mechanical properties was prepared with carboxymethyl cellulose and acrylic acid as raw material, while octagon melon ring and bentonite as double crosslinking agent. The structure and morphology of the prepared gel were characterized by FT-IR and SEM. The mechanical properties, adsorption properties, swelling and adsorption kinetics of the gel were investigated. The results show that CB[8] and BET formed a dense network structure through hydrogen bonding with AA grafted to CMC, which enhanced the mechanical properties of the gel;The swelling of the gel conforms to the quasi-second-order kinetic model and the theory of stress relaxation swelling hemicrystalline polymer; After the gel was soaked in acid, the hydrogen bond between the free H+ in the acid and CB[8] and BET significantly increased the breaking strength of the gel from 0.52 MPa to 3.0 MPa; The gel has a good adsorption effect on methylene blue, which accords with the quasi-second-order kinetic model.
