Their electric capacitance depends on the configuration of parallel conductive plates and the permittivity of the dielectric material. The properties of composite materials can be altered by varying their filler structures. We examine the influence of chain-like structures introduced into polydimethylsiloxane-iron particle dielectric composites on its permittivity using numerical approaches. Parameters studied include the filler volume fraction, clearance between the chain ends and the conductive plates, spacing between adjacent chains, inter-particle spacing within each chain, and radius of the filler particles. The permittivity increases with volume fraction and inter-chain spacing but decreases as particle size increases. The introduction of chains into polydimethylsiloxane(PDMS) increases the permittivity up to ≈ 1.8 times that of composite with randomly distributed particles, but the particle must be connected for this enhancement. This result is useful for further development of the electrical applications of elastomeric composites.
