Abstract
The broadband dielectric properties of composites of poly(ϵ-caprolactone) (PCL) and Mo6S3I6 (MoSI) nanowires at loadings up to 5 wt% were investigated. Three different relaxations were observed for these composites, two relaxations are associated with the polymer matrix and the lower temperature relaxation originates from the nanowires. No significant increase in a.c. conductivity was observed when the nanowires were introduced to the polymer. The only impact of nanowires on the polymer was seen at lower temperatures (T < 100 K), where another relaxation occurs when the concentration of nanowires was increased. Temperature dependency of relaxation time follows Arrhenius behavior. Activation energy was determined and it is concentration independent.
