After surface-modified with silane coupling agent(KH792),small-sized glass microbeads(GMs)were coated with silver by using electroless plating technique with glucose as reducing agent to produce composite particles GMs@Ag.The effects of different surfactants on the phase,microstructure,appearance and electrical properties of the samples were investigated.The composite particles were used as conductive filler to prepare flexible electromagnetic shielding fabric,and the electromagnetic shielding performance was tested.The results show that when the composite surfactants of polyvinylpyrrolidone and acacia was added,the resulting GMs@Ag coating was compact,uniform and continuous with a powder resistivity of 12.4 mΩ·cm.With 70%of the addition amount,the electromagnetic shielding efficiency of the coating could reach more than 40 dB,showing a potential for application in electromagnetic shielding field.
