不同的应用需要提供改进的特性和功能的可充气传导装置。然而，制造高性能可充气装置的困难部分是能够在可充气导管上实现具有受控结构的二维（2D）可充气。在这里，我们报告的高度可膨胀的设备与可控结构的制造，通过包裹的超对齐的碳纳米管片（SACNS）的预膨胀导管。所得到的结构具有独特的二维屈曲结构，包括准平行屈曲，交叉屈曲和分级屈曲结构，这使得可逆的结构变化的7470%的体积应变。在大应变充放气循环过程中，2D SACNS屈曲结构显示出稳定的电导率和表面润湿性。展示了基于这些结构的充气式设备，包括充气式肿瘤消融、电容式体积应变传感器以及通过充气式射频天线进行通信。
Inflatable conducting devices providing improved properties and functionalities are needed for diverse applications. However, the difficult part in making high-performance inflatable devices is the enabling of two-dimensional (2D) buckles with controlled structures on inflatable catheters. Here, we report the fabrication of highly inflatable devices with controllable structures by wrapping the super-aligned carbon nanotube sheet (SACNS) on the pre-inflated catheter. The resulting structure exhibits unique 2D buckled structures including quasi-parallel buckles, crisscrossed buckles, and hierarchically buckled structures, which enables reversible structural changes of 7470% volumetric strain. The 2D SACNS buckled structures show stable electrical conductance and surface wettability during large strain inflation/deflation cycles. Inflatable devices including inflatable tumor ablation, capacitive volumetric strain sensor, and communication via inflatable radio frequency antenna based on these structures are demonstrated.
