제목 Improvement of Mechanical Property of Ion gels by Star-shaped Block Copolymer and Its Application to Electrochemical Devices
초록 Mechanical resilience is very important property of iongels for its application to electronic devices. There are some ways for increasing the mechanical property but they are too complicate and need harsh condition to applicate to devices. Here, we prepared new materials for ion-gels based on star-shaped block copolymer composed by poly(styrene) (PS) and poly(methyl methacrylate) (PMMA). The gels with star (PMMA-b-PS)6 show significantly higher elastic modulus than the gels with analogous linear PS-b-PMMA-b-PS triblock copolymers at same condition. In addition, star (MS)6 iongels exhibited superior recovery than the corresponding linear SMS iongels when subjected to repeated strain cycles. To demonstrate that these materials can be used as solid‐state electrolytes, the iongels are functionalized by incorporating ECL luminophores Ru(bpy)32+ and are applied to ECL devices. Moreover, flexible ECL devices are fabricated to take advantage of the mechanical properties of the gels.
