Recyclable and super-stretchable conductive elastomeric composites with a carbon nanostructure interconnected network structure for effective thermal management and excellent electromagnetic wave suppressor.

The increasing demand for flexible electronics and portable gadgets has resulted in an increase in the amount of emitted EM radiation in recent years. Conductive carbon black (VCB XC 72) is a quasi-graphitic structure of clustered carbon particles that was deemed an ideal material for the development of extremely flexible electromagnetic interference (EMI) shielding materials. The sequential solution and melt mixing process has been used to generate a flexible and recyclable zinc oxide cross-linked, and VCB XC 72 nanofiller reinforced EMI shielding material. The ionic cross-linked network, created by other self-clustering ion duplets of Zn2+ ions, gave rise to the amazing recycling and reprocessing abilities of carboxylated acrylonitrile butadiene rubber (XNBR). The cross-linked XNBR and conductive black combination formed a tunable inferential framework that provided absorption, reflection, and multiple reflection shielding mechanisms. Based on the findings of the morphological study, it has been determined that the scattered and distributed carbon black clusters included inside XNBR rubber are creating the pathway for electrical hopping. As a result, the electrical percolation threshold has been lowered, and EMI shielding has significantly improved. The rubber composites had improved thermal characteristics in addition to having outstanding mechanical performances. Hopefully, these findings will pave the way forward for the development of smart electronic devices and environmentally friendly EMI shielding materials. [ABSTRACT FROM AUTHOR]
