Abstract :
[en] Charge transfer processes between polyester and conductive fibre surfaces is studied using Kelvin probe force microscopy (KPFM). Three model systems are considered: a single isolated insulating polyester fibre, two conductive stainless steel fibres in galvanic or non-galvanic contact and an insulating polyester fibre in galvanic contact with a conductive stainless steel fibre. For first and third configurations, a two-stage process with two different time constants is observed corresponding to two mechanisms responsible for the charge transfer. For the second configuration, a single-stage process is observed. The presence of the conductive fibre facilitates the charge transfer on the insulating fibre.
