The　rapid　development　of　photochromic　devices　has　stimulated　great　enthusiasm　for　the　design　and　preparation　of　luminescent　materials.　Introducing　fluorescent　powder　ZnS:Cu　into　the　cross-linked　polymer　matrix　is　an　efficient　and　simple　method　to　obtain　photochromic　materials　with　excellent　comprehensive　performance.　However,　the　traditional　method　is　to　directly　introduce　fluorescent　powder　into　the　polymer　matrix　by　physical　mixing.　This　not　only　increases　the　internal　defects　of　the　polymer　and　reduces　the　mechanical　properties,　but　also　hinders　the　fluorescent　powder　from　absorbing　external　energy　and　reduces　its　luminescence　efficiency.　In　addition,　few　studies　have　focused　on　recyclable　photochromic　luminescent　materials.　Inspired　by　dynamic　covalent　cross-linking　technology,　this　paper　first　modified　fluorescent　powder　with　3-mercaptopropionic　acid　and　then　introduced　it　into　epoxy　silicone　rubber　to　prepare　recyclable　luminescent　elastomer.　Compared　with　traditional　physical　blending,　the　mechanical　properties　and　luminescence　performance　of　the　covalently　bonded　luminescent　elastomer　were　improved.　Excellent　mechanical　properties　and　luminescence　performance　were　maintained　in　multiple　recycling　processes.　This　paper　provides　a　feasible　and　simple　scheme　for　the　preparation　of　recyclable　luminescent　elastomers,　paving　the　way　for　the　recycling　and　long-term　utilization　of　photochromic　luminescent　materials.　©　2023　Society　of　Plastics　Engineers.
