Abstract

We report rapid fabrication of a nanofibrillar PEDOT microsupercapacitor (MSC) using an inexpensive MOPA fibre laser. Simultaneous laser engraving and ablation produce a carbon fibre interdigitated microelectrode and a hematite film. The polymer deposited via the vapour phase leads to stable cyclability for 10 000 cycles in a MSC. This journal is © The Royal Society of Chemistry, 2026.
