Charge-Triggered Self-Assembled Carbon Nanotube Construct for Efficient Emi Shielding

Abstract
The widespread usage of miniaturized electronic gadgets today faces stiff reliability obstacles from factors like stray electromagnetic signals. The challenge is to design lightweight shielding materials that combine small volume and high-frequency operations to reliably reduce/eliminate electromagnetic interference. Herein, in the first of its kind, a sequential interpenetrating polymeric network (IPN) membrane was used to host a CNT construct through a stimuli responsive trigger. The proposed construct besides being robust, sustainable, and scalable is a universal approach to fabricate a CNT construct where conventional strategies are not amenable. This approach of self-assembling counter-charged CNTs also maximizes the number of CNTs in the final construct, thereby greatly enhancing the shielding performance (dominated by 90%-absorption in a wide frequency band of 8.2-26.5 GHz). The IPN-CNT construct achieves specific shielding effectiveness in the range of ca. 1607-5715 dB cm2 g-1 by tuning the thickness of the CNT construct. The performance of such ultra-thin, light-weight IPN-CNT construct remained unchanged when subjected to 10,000 bending cycles and on exposure to different chemical environments, indicating outstanding mechanical/chemical stability.
