Abstract
Transient electronics is an emerging class of functional electronics designed to address problems such as potential data leakage and information theft. In order to meet the unification of transient technology and electronics, we prepared a flexible conductive energetic film by assembling energetic ionic liquids (EILs) loaded single-walled carbon nanotubes (SWNTs) and CuO functionalized multi-walled carbon nanotubes (MWNTs). It was found that the interaction between EILs and SWNTs maintains the high conductivity of SWNTs and strengthens the flexibility of the film. The introduce of CuO functional MWNTs enhance the detonation performance of the films by catalyzing EILs combustion. Therefore, obtained flexible conductive energetic film has good conductivity (63.67 S/cm), high energy release (8037 kJ/kg), and high flexibility (1000 bends). It is confirmed that flexible conductive energetic film can meet the requirement of low-voltage operation and high-voltage self-destruction by replacing traditional circuit in an electronic device. The prepared transient chip is able to ignited in 10 ms and completely self-destruct within 0.7 s.
