摘要: Oxidized multiwall carbon nanotubes (o-MWCNTs) were introduced into silicone foam to fabricate an electromagnetic interference (EMI) shielding material with high gamma radiation stability by solution casting followed foaming and cross-linking reactions. The as-prepared o-MWCNT/silicone composites exhibited excellent mechanical strength effective EMI properties superior effectiveness (SE) ranging from 26 73 dB at a 0.5–6.4 mm thickness 30 wt% o-MWCNTs in the Ku band. Moreover, have good stability, showing relatively stable improvement of hardness pressure resistance after irradiation absorbed dose 500 kGy. These results indicate that composite is attractive candidate for some ionizing environments.
