Multiwalled carbon nanotubes MWCNTTs were dispersed in sliccone rubber matrix by ultrasonication and intense stirring to prepare MWCNT-polymer composites for electromagnetic inteference shielding application. The structure and morphograpy of MWCNTs and composites were observed by scanning electron microscope SEM and transmission electron microscope TEM. Electromagnetic interference EMI shielding effectiveness SE were measured by AV360 vector network analyzer. The experimental results demonstrated MWCNT-siliccone rubber composites have good properties of EMI shielding. EMI SE reached 27-30dB at band of 100-1000MHz.
