It has been a significant challenge to prepare multiple-response hydrogels with both lower critical solution temperature (LCST) and upper critical solution temperature (UCST). This work reports the synthesis of methyl cellulose-graft-polyacrylamide (MC-g-PAM) hydrogels by ceric ion initiated graft polymerization. Mechanically strong MC-g-PAM hydrogels combine LCST and UCST in one system (LCST > UCST), which provides a transparent “temperature window”. The range of this temperature window can be tuned by changing cellulose contents or adding sodium chloride. In addition, the transmittance of MC-g-PAM hydrogels can be precisely controlled via application of varied DC voltage. These desirable properties make the MC-g-PAM hydrogels as smart materials.

具有可调LCST和UCST的多种刺激响应性纤维素水凝胶作为智能窗口

制备具有较低临界溶液温度（LCST）和较高临界溶液温度（UCST）的多响应水凝胶是一项重大挑战。这项工作报道了由铈离子引发的接枝聚合反应合成甲基纤维素-接枝-聚丙烯酰胺（MC- g- PAM）水凝胶。具有机械强度的MC- g -PAM水凝胶将LCST和UCST结合在一个系统中（LCST> UCST），提供了透明的“温度窗口”。该温度窗口的范围可以通过改变纤维素含量或添加氯化钠来调节。此外，可以通过施加变化的直流电压来精确控制MC- g -PAM水凝胶的透射率。这些理想的特性使MC- g-PAM水凝胶作为智能材料。
