研究领域
1. 神经元传感器电极表面修饰
神经电界面是神经电极和神经元细胞间构建电突触的工作界面,在脑组织与外部设备间建立直接连接通路。本人近年来从事研究CNT垂直阵列、导电高分子及生物水凝胶协同的3-D纳米微结构神经电界面,主要研究修饰后神经元传感器电极的电化学特性和生物相容性。
2.高分子基CNT复合材料的界面设计
针对纳米尺度碳纳米管新型增强体,需要设计结构新颖的力承载与传递结构单元。研究内容侧重于提高碳管含量、增大界面强度、使碳管在基体中能够定向且伸直,在研究中提出了一系列界面设计的方法:反应纺丝法制备取向碳纳米管,超支化高分子表面接枝,共价键法建立界面化学作用等。
3.纳米石墨烯的制备与应用
单层石墨烯是真正意义上的二维原子晶体,具有超高的机械强度、良好的导电导热性能以及独特的电学性质,有望成为组建纳米电子器件的最佳材料。我们目前进行的工作主要包括液相超声法及有机介质还原法制备石墨烯,同时将制备的石墨烯应用于透明导电薄膜等光电器件。
