The　droplet　breakup　technology　can　effectively　increase　the　generation　throughput　and　adjust　the　droplets　size,　which　has　an　important　impact　on　the　performance　of　the　double　emulsion　droplets　in　medical,　chemical,　and　other　applications.　This　work　presents　an　experimental　study　on　the　breakup　regimes　of　double　emulsion　droplets　after　their　on-chip　generation.　Five　distinct　breakup　regimes　are　categorized　according　to　the　breakup　times　and　the　existence　of　the　coupling　effect　during　breakup　process.　Evolutions　of　the　neck　widths　and　thinning　rates　of　both　inner　droplets　and　outer　droplets　are　provided　to　discuss　the　dynamics　of　different　regimes　as　well　as　different　stages.　In　particular,　the　influences　of　the　coupling　effect　on　the　interfacial　evolution,　collapsing　mechanism,　force　analysis,　and　breakup　critical　condition　are　confirmed　by　comparisons　with　the　results　of　single　emulsion　droplets.
