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.
