Electrochromic　fabrics　(ECFs)　have　demonstrated　great　potential　in　developing　wearable　products　for　applications　in　wearable　displays　and　adaptive　camouflage.　Nonetheless,　the　lack　of　device　integration　usually　makes　ECFs　not　as　flexible　and　lightweight　as　regular　textiles.　Herein,　we　developed　a　highly　integrated　all-in-one　ECF　by　assembling　all　the　essential　components　into　a　piece　of　nylon　fabric.　The　configuration　is　based　on　EC-active　polyaniline,　Au　reflector　electrode　and　alumina　counter　electrode　coating　on　both　sides,　and　a　gel　electrolyte　filling　into　the　fabric.　As　a　result,　the　all-in-one　ECF　has　an　ultrathin　thickness　of　only　80　μm,　which　offers　flexibility　superior　to　that　of　conventional　ECFs.　Stemming　from　the　optical　modulation　between　top　PANI　coating　and　a　bottom　Au　reflector,　the　all-in-one　ECF　could　deliver　color　switches　between　yellow　and　green,　which　are　two　typical　environmental　camouflage　colors.　It　also　demonstrates　thermal　management　based　on　IR　modulation　behavior.　Moreover,　the　dual-band　optical　modulation　has　excellent　stability　in　response　to　mechanical　bending,　twisting,　and　tailoring.　Considering　excellent　wearability　and　active　optical　modulation,　the　all-in-one　ECF　was　further　developed　into　an　unmanned　environmental　adaptive　camouflage　prototype　system　by　integrating　with　sensing　and　control　modules,　which　exhibit　fast　color　blending　with　dynamic　environment　background.　The　construction　strategy　of　highly　integrated　ECFs　proposed　in　this　work　could　equally　well　apply　to　other　EC-active　materials　and　anticipated　to　provide　new　insights　into　developing　high-performance　intelligent　applications,　such　as　wearable　displays　and　military　camouflage　clothing.　©　2024　The　Royal　Society　of　Chemistry.
