摘要
基于石墨烯的三维(3D)聚合物/石墨烯气凝胶具有优良的机械性能是其广泛应用的关键。因为聚合物在石墨烯溶液中差的分散性和兼容性,制备这样的聚合物/石墨烯气凝胶仍然是具有挑战性的。本文在表面活性剂的帮助下采用直接冻干自组装的方法成功制备了多孔、轻质、超弹(80%)和高强度(80k Pa)三维聚苯乙烯/石墨烯气凝胶(MPS-GAs)。同时所制备的MPS-GAs具有优异的电化学性能、循环稳定性和灵敏的电阻响应,在驱动器、弹性导体、压力传感器和可穿戴器件方面有很好的应用前景。
Three-dimensional(3D) graphene-based polymer/graphene aerogels with excellent mechanical properties are crucial for broad applications. The creation of such polymer/graphene aerogels remains challenging because of the poor dispersion and compatibility of polymer within graphene matrix. By use of the freezing-directed assembly of graphene under the assistance of surfactant,3D macroporous polystyrene/graphene aerogels(MPS-GAs) with lightweight, superelastivity(80% strain), high strength(80 kPa) and good electrical properties have been achieved in this study. The as-prepared MPS-GAs shows excellent electromechanical performance with stable cyclic resilient property and sensitive resistance response, making the MPS-GAs promising candidates for applications in actuators, elastic conductors, strain/pressure sensors and wearable devices.
