MXene-GO Thin Film Driver Based on Humidity Control

本文将MXene和氧化石墨烯混合,制备成薄膜驱动器并探究其湿度驱动性能,分两个部分。第一部分是利用改进的Hummers方法制备氧化石墨烯和利用HCl/LiF刻蚀MAX制备Ti3C2TX MXene,将所制备的两种原料混合抽滤成MXene-氧化石墨烯薄膜,藉由SEM、AFM、拉曼光谱和XRD检测分析原料制备以及MXene-氧化石墨烯薄膜的性质;第二部分是基于MXene-氧化石墨烯薄膜对水分湿度响应的特性,分别测试Ti3C2TX MXene薄膜、氧化石墨烯薄膜和MXene-氧化石墨烯薄膜的不同湿度条件下弯曲角度的关系。实验结果得出,MXene-氧化石墨烯薄膜在20℃,相对湿度90˚的条件下达到最大弯曲角度148˚,同时对其稳定性进行检测,结果表明MXene-氧化石墨烯薄膜在水中能长时间保存,证明了它的长期稳定性。

In this paper, MXene was mixed with graphene oxide to prepare a thin film driver, and its humidity driving performance was investigated in two parts. The first part is to use the improved Hummers method to prepare the mixture of GO and HCl and LiF, etch MAX to prepare Ti3C2TX MXene, and then mix and filter the two prepared raw materials into MXene-GO thin film. The material preparation and properties of MXene-GO films were analyzed by SEM, AFM, Raman spectroscopy and XRD. The second part is to test the relationship between bending angles of Ti3C2TX MXene thin film, GO thin film and MXene-GO thin film under different humidity conditions, based on the response characteristics of MXene-GO thin film to moisture and humidity. The experimental results show that MXene-GO film can reach the maximum bending Angle of 148˚ at 20˚C and relative humidity of 90˚. At the same time, the stability of MXene-GO film is tested. The results show that MXene-GO film can be preserved in water for a long time, proving its long-term stability.
