Nowadays

the rapid development of flexible wearable electronic devices

aerospace and other fields has increased the demand for flexible

lightweight electromagnetic interference (EMI) shielding materials

carbon nanotubes/polymer-based composites have attracted much attention because of their good flexibility

light weight

excellent electrical conductivity and mechanical stability

and adjustable EMI shielding efficiency. In this paper

the electromagnetic shielding mechanism is introduced

the dispersion method of carbon nanotubes and the preparation method of carbon nanotubes/polymer-based flexible EMI shielding composites are compared and summarized

and the research progress of carbon nanotubes/polymer-based flexible EMI shielding composites is reviewed. Finally

the key scientific problems to be solved urgently for carbon nanotubes/polymer-based flexible EMI shielding composites are proposed

and their future development trend is prospected.
