Abstract A series of composites based on polypropylene with different loadings of nickel-coated cellulose fi bres
(NCCF) were fabricated with the aim to create a composite suitable for EMI shielding and/or electrostatic
discharge application. Various properties such as EMI shielding effectiveness, surface resistivity, volume
resistivity and fl exural strength were characterised according to ASTM standard. Both surface and volume
resistivity suggested that the electrical conductivity of NCCF was not high enough and the composite
remains electrically non-conducting up to 40 wt% loading of NCCF. However, nickel particles were still able
to shield electromagnetic radiation regardless of their connectivity and conductivity. This… More >
