Abstract

A series of thermoresponsive hydrogels containing positively charged groups in the polymeric network were synthesized and modified with the electroactive compound 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS). ABTS, which forms a dianion in aqueous solutions, acts as an additional physical cross-linker and strongly affects the swelling ratio of the gels. The influence of the amount of positively charged groups and ABTS oxidation state on the volume phase transition temperature was investigated. A hydrogel that possesses a relatively wide and well-defined temperature window (the temperature range where changes in the ABTS oxidation state affects the swelling ratio significantly) was found. The influence of the presence and oxidation state of ABTS on mechanical properties was investigated using a tensile machine and a rheometer. Then, a very thin layer of the gel was deposited on an Au electrochemical quartz crystal microbalance with dissipation (EQCM-D) electrode using the electrochemically induced free radical polymerization method. Next, chronoamperometry combined with quartz crystal microbalance measurements, obtained with an Au EQCM-D electrode modified by the gel, showed that the size of the thin layer could be controlled by an electrochemical trigger. Furthermore, it was found that the electrosensitivity could be modulated by the temperature. Such properties are desired from the point of view construction of electrochemical actuators.

摘要

一系列含有聚合物网络中带正电荷基团的温敏水凝胶被合成，并通过电化学活性化合物 2,2'-联氮双(3-乙基苯并噻唑啉-6-磺酸)二铵盐（ABTS）进行修饰。ABTS 在水溶液中形成二阴离子，充当额外的物理交联剂，并强烈影响凝胶的溶胀比。研究了带正电荷基团的量和 ABTS 氧化态对体积相转变温度的影响。发现了一种具有相对较宽且定义良好的温度窗口的水凝胶（ABTS 氧化态变化显著影响溶胀比的温度范围）。使用拉伸机和流变仪研究了 ABTS 的存在和氧化态对机械性能的影响。然后，使用电化学诱导自由基聚合方法将很薄的一层凝胶沉积在带有耗散的金电化学石英晶体微天平（EQCM-D）电极上。接下来，使用带有凝胶修饰的 Au EQCM-D 电极进行的计时安培法结合石英晶体微天平测量表明，通过电化学触发可以控制薄层的尺寸。此外，发现可以通过温度来调节电灵敏度。从电化学致动器的构建角度来看，这些特性是理想的。
