    Notes: Abstract Electric and magnetic properties of composite materials consisting of low density polyethylene filled with powdered ferromagnetic materials were investigated. The volume fractions of the fillers were varied from 10% up to the theoretical maximum packing fractions, i.e. between 0.70 and 0.77, so that the percolation phenomenon could be investigated. The ferromagnetic fillers used were HyMu 800 (a nickel–iron–molybdenum alloy), MnZn ferrite and NiZn ferrite. The particle sizes and size distributions of the fillers were well characterized by image analysis techniques. Based on the particle size distribution the maximum loading levels of fillers as permitted by geometric considerations were calculated. The properties of the composites characterized included: volume and surface resistivities, dielectric constants, electrical loss factors and magnetic permeabilities.

    Notes: Abstract D.c. electrical properties of low-density polyethylene filled with stainless steel fibres have been studied at various concentrations above the percolation threshold. The volume fractions used were 2, 5 and 10% of stainless steel fibre. The volume resistivity of polyethylene varied between 6.15×107 Ω cm at 2% loading level and 3.71×105 Ωcm at 10%. Corresponding values for surface resistivity varied between 2.77×107 Ω at 2% and 3.94×104 Ω at 10%. The value of the critical exponent for percolation was estimated to be around 2.4 for volume resistivity and 3 for surface resistivity.
