The　collision　of　droplets　with　solid　surfaces　is　a　common　phenomenon　in　nature.　However,　droplets　exhibit　interesting　motion　states　when　captured　by　surfaces.　This　work　investigates　the　dynamical　behavior　and　the　wetting　condition　of　droplets　captured　by　different　surfaces　in　electric　fields　via　molecular　dynamics　(MD)　simulations.　By　adjusting　the　initial　velocity　of　droplets　(V-0),　electric　field　intensity　(E)　and　directions,　the　spreading　and　wetting　properties　of　droplets　are　analyzed　systematically.　The　results　indicate　that　the　electric　stretching　effect　occurs　when　a　droplet　strikes　the　solid　surface　in　electric　fields　and　the　stretch　length　(h(t))　of　droplets　continuously　increases　with　the　enhancement　of　E.　In　the　low　field　strength　regime,　the　direction　of　electric　fields　has　an　effect　on　h(t):　the　value　of　h(t)　is　larger　in　the　case　of　positive　electric　fields　as　compared　to　negative　electric　fields.　In　the　high　field　strength　regime,　the　direction　of　electric　fields　makes　no　difference　to　h(t):　the　droplet　is　stretched　observably,　and　the　breakdown　voltage　U　is　calculated　to　be　0.57　V　nm(-1)　under　both　positive　and　negative　electric　fields.　Droplets　impacting　with　surfaces　at　initial　velocities　display　various　states.　The　droplet　bounces　off　the　surface　regardless　of　the　direction　of　electric　field　at　V-0　＞=　1.4　nm　ps(-1).　The　maximum　spreading　factor　beta(max)　and　h(t)　both　increase　with　V-0　and　are　not　affected　by　field　directions.　The　simulation　results　are　consistent　with　experiments,　and　the　relationships　between　E,　beta(max),　h(t)　and　V-0　are　proposed,　which　provide　the　theoretical　basis　for　large-scale　numerical　calculations　such　as　computational　fluid　dynamics.
