A　rapid　fabrication　method　for　conducting　poly(vinylidene　fluoride)　by　creating　active　centre　using　KrF　excimer　laser　direct　etching　technique　is　demonstrated.　Study　shows　that　the　etching　point-defects　and　line-defects　perform　active　centre　function　for　facilely　controlling　conducting　layer　when　laser　irradiation　decreases　the　laser　threshold.　The　results　of　laser　scanning　confocal　microscope(LSCM)　and　scanning　electron　microscope(SEM),　indicate　that　the　2D　net-like　microstructures　surround　the　defects　are　the　precursor　of　conducting　layer,　which　significantly　affect　the　velocity　of　preparation.　The　effect　of　laser　thermal　cross-linking　reaction　and　laser　irradiation　cross-linking　reaction　together　contributes　to　the　rapid　formation　of　great　conducting　layer.
