This　article　investigates　the　equilibrium　arrangement,　self-assembly　process,　and　subsequent　curing　of　amphiphilic　snowman-shaped　Janus　particles　at　the　oil-water　interface.　The　independent　Janus　particles　are　in　vertical　equilibrium　state　and　the　contact　position　of　the　oil-water　interface　is　at　the　largest　cross　section　of　the　particle＇s　hydrophobic　phase.　Under　the　effect　of　the　surface　tension　and　the　adsorption　of　materials,　Janus　particles　may　form　particle　combinations　including　the　particle　pairs　and　the　particle　triangle,　whose　inner　and　outer　sides　have　the　liquid　surface　exhibiting　completely　opposite　contact　angles.　Particle　combinations　form　stable　parallel　double-chain　structures　with　diverse　shapes　after　the　self-assembly　process.　However,　the　single　Janus　particles　attain　a　state　of　mechanical　equilibrium　under　the　influence　of　surrounding　particles,　enabling　them　to　assemble　into　regular　array　structures.　The　relationship　of　interfacial　tension　coefficient　between　phases　can　be　changed　by　adjusting　the　oil-water　system,　which　leads　to　variations　in　the　self-assembly　speed　and　the　final　arrangement　results.　The　thin-film　with　uniformly　distributed　vertical　particles　is　achieved　by　replacing　the　underlying　deionized　water　with　a　curing　agent.　Based　on　the　understanding　of　the　interactions　between　irregularly　shaped　Janus　particles　at　the　oil-water　interface,　it　will　be　convenient　to　achieve　the　controllable　self-assembly　and　widely　applications　of　these　particles.
