Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p> <bold>The use of α, ω‐alkanedisulfonic acid, HO₃S(CH₂)_{<italic>n</italic>}SO₃H (<italic>n</italic> = 1, 4, 6 and 12), as a dopant for polyaniline (PANi) was investigated. This series of disulfonic acids with varying chain lengths were synthesized and used in the doping of PANi. The doped polymers showed conductivity in the range 10⁻² to 10⁻¹ S cm⁻¹. Thermal studies showed that the doped polymers, depending on the chain length of α, ω‐alkanedisulfonic acid, were stable up to <italic>ca</italic> 300 °C and the thermal stability decreased with increasing dopant chain length. The thermal stability of α, ω‐alkanedisulfonic acid‐doped PANi was higher than that of alkanesulfonic acid‐doped PANi which typically degrades around 250 °C, suggesting a moderately broader processing window for α, ω‐alkanedisulfonic acid‐doped PANi for blending with other thermoplastics.
