A nature-inspired strategy has been developed to prepare polyvinyl alcohol (PVA)/catechol-modified quaternized chitosan (QCS-C)/MXene hydrogels with good self-adhesion, frost-resistance, and high ion-conductivity. The PVA/QCS-C/MXene hydrogel shows an ionic conductivity of 8.82 S m and a gauge factor of 33.53 at low strain (0-10%), and remains flexible and conductive at -47 °C. The PVA/QCS-C/MXene hydrogel displays promising potential as an ionically conductive hydrogel sensor for applications in flexible electronic devices.
已经开发出一种受自然启发的策略，以制备具有良好自粘性、抗冻性和高离子导电性的聚乙烯醇（PVA）/儿茶酚改性季铵化壳聚糖（QCS-C）/MXene水凝胶。PVA/QCS-C/MXene水凝胶在低应变（0-10%）下显示出8.82 S m的离子电导率和33.53的应变系数，并且在-47°C下仍保持柔韧性和导电性。PVA/QCS-C/MXene水凝胶作为一种离子导电水凝胶传感器在柔性电子器件中的应用显示出广阔的前景。
