Abstract
Abstract
Mechanical and electromagnetic interference shielding composites containing Ag-plating micro-nano cellulose fibers (ANCFs) were prepared as multifunctional materials. ANCFs, as electromagnetic wave reflection filler containing micro-nano cellulose fibers (NCFs) used as the structural component to reinforce the mechanical strength and Ag enhancing electromagnetic shielding effectiveness, were prepared by electroless Ag-plating technology on NCFs surfaces. Ag coating had a thickness of 60 µm without the oxide phase detected. The incorporation of 5 wt % ANCFs into epoxy (EP) substrate yielded impact strength and flexural strength of 1.84 kJ/m2 and 41.6 MPa, which is approximately 2.4 times and 1.41 times higher than EP. The ANCFs-EP composite performed an electromagnetic shielding effectiveness of 34–25 dB at a frequency of 90 kHz in the electromagnetic wave; the EMI shielding effectiveness was improved obviously up to 34 dB, which can meet the requirement of general places.
