**Abstract**
 An EVA-carbon nanofibre (CNF) nanocomposite was developed and its electromagnetic interference (EMI) shielding effectiveness (SE) was measured in the frequency range of 8-12 GHz. The dependence of SE on the applied electromagnetic frequency and the amount of filler loading was evaluated. The SE of the composites was found to be directly proportional to the applied electromagnetic frequency and the amount of filler. Incorporation of 16 wt % of CNF produced the optimum SE. The AC conductivity of the CNF-reinforced EVA composites was also measured in order to correlate the conductivity values with the SE of the respective composites. The level of filler loading governed the conductive network formation and hence the SE and conductivity. In order to perform a comparative study of SE, three other carbon-based nanofillers, i.e. multiwalled carbon nanotube, expanded graphite and conductive carbon black, were used. Morphological studies using TEM supported various findings. These results indicate that CNF is an effective filler for the development of composites with excellent EMI shielding capability. 21 refs.
