Two-dimensional nanomaterials could be potentially applied in the field of brain–computer interface due to their significant inductive effect during ion permeation. In order to tune the inductive signal through the microstructure, a membrane based on MXene-grafted β-cyclodextrin (β-CD) was prepared, and its electrochemical performance was recorded. The experimental results confirmed that β-CD has been successfully intercalated into the gallery between the MXene sheets, and the intercalation induced a weaker inductive effect of MXene in the ion diffusion process. Moreover, the results indicated that easier ion diffusion through the membrane could result in weaker inductance. Besides, the experimental results were roughly analyzed by the back-propagation (BP) neural network to compare the contribution of the influence factors. The results suggested that tunable inductance can be achieved by constructing a certain interlay spacing of MXene, which could be potentially used to design microsized inductors in biological applications.

β-环糊精嵌入对 MXene 膜的诱导作用

二维纳米材料在离子渗透过程中具有显着的诱导作用，因此有望应用于脑机接口领域。为了通过微观结构调节感应信号，制备了一种基于 MXene 接枝的 β-环糊精 (β-CD) 的膜，并记录了其电化学性能。实验结果证实，β-CD 已成功嵌入到 MXene 片层之间的通道中，并且嵌入在离子扩散过程中诱导了 MXene 较弱的诱导效应。此外，结果表明，更容易通过膜的离子扩散可能导致更弱的电感。此外，通过反向传播（BP）神经网络对实验结果进行粗略分析，比较影响因素的贡献。
