The　traditional　camouflage　infrared　stealthy　coating　hits　the　target　by　controlling　the　emissivity　and　deform　disguise,　then　the　stealthy　efficiency　will　be　low　when　the　target　temperature　is　obviously　different　from　the　environment.　In　order　to　enhance　the　infrared　stealthy　efficiency,　the　idea　of　phase　changed　temperature-controlling　complex　coating　design　is　suggested　in　this　paper.　The　shortcomings　of　the　traditional　stealthy　coating　by　means　of　low　emissivity　or　infrared　distortion　is　discussed.　The　idea　that　the　thermal　infrared　composite　coating　can　not　only　adapt　to　single　or　intricate　backgrounds　but　also　withstand　different　bands　thermal　imaging　system　is　put　forward.　From　the　aspect　of　structure,　function　and　feasibility　of　the　coating.　It　shows　good　temperature　reduction　and　control　function,　and　it　is　favorable　for　achieving　infrared　blending.
