Article Abstract

Facing the increasing electromagnetic interference (EMI) pollution in the living environment, it is a new trend to explore an efficient EMI shielding material with facile fabrication and a wide range of application scenarios. A hydrophobic composite paper composed of silver nanowires (AgNWs) and kapok microfibers cellulose (MFC) was modified by methyl trimethoxy silane (MTMS) through a simple method. As a result, the composite paper has a good EMI shielding effectiveness (EMI SE) of 61.7 dB with electrical conductivity of 695.41 S/cm. The modification of MTMS improved the thermal stability performance of composite paper, which also increased its water contact angle to 113°. The free silver ions (Ag) released from AgNWs can kill surrounding microbial bacteria, endowing the composite paper with good antibacterial property. Water resistance and antibacterial property enable MTMS/AgNWs/MFC composite paper to cope with complex application environments.

Achieving high capacitance while maintaining rapid charge transport and structural stability remains a major challenge in the design of battery-type supercapacitor electrodes. Herein, a molecularly engineered strategy is presented for constructing hierarchical hybrid electrodes by integrating petal-like NiCu-LDH nanosheets onto 3D HBC-x (x = H, F, OMe)-functionalized CNT paper via a one-step hydrothermal process. The incorporation of HBC effectively mitigates CNT agglomeration and constructs an interconnected conductive framework that enhances charge transport, shortens ion diffusion paths, and reduces internal resistance.
