Abstract

石墨烯的宏量制备及其后续处理工艺对全面实现这一有趣二维纳米材料的潜在应用起着至关重要的作用. 在此, 我们采用一种烷基 枝化的Percec型枝化分子(3,4,5-三十八烷基苯基醚-1-甲醛, 1)作为稳定剂, 利用液相剥离石墨粉的方法, 制备了具有低缺陷、热响应性能的 智能石墨烯分散液. 通过简单地改变温度, 便能实现处于分散状态的石墨烯与稳定剂1的分离和回收利用. 除了上述非共价缠绕, 稳定剂1 也能够通过[3+2]环加成反应共价修饰于石墨烯表面. 修饰后的石墨烯在多种有机溶剂中表现出比未修饰石墨烯更好的分散性, 从而为进 一步将其引入聚合物体系创造了条件. 本文所示的方法提供了一种制备智能石墨烯分散液以满足多种应用的新思路.
