Magnesium　oxychloride　(MOC)　cement　as　viable　substrate　candidate　has　unique　applications　in　a　range　of　functional　and　novel　sensing　applications　due　to　their　low　thermal　conductivity,　high　toughness,　durability　and　excellent　fire　resistance.　Here,　we　developed　a　facile　strategy　to　fabricate　metallized　patterns　on　MOC　cement　composites　through　laser-induced　selective　metallization.　The　laser　sensitiser　of　copper　hydroxyl　phosphate　[Cu2(OH)PO4]　was　incorporated　into　MOC　cement　to　prepare　MOC　cement　composites.　Then,　the　metallized　copper　patterns　were　obtained　on　MOC　cement　composites　after　1064　nm　pulsed　laser　activation　and　electroless　copper　plating　(ECP).　The　obtained　copper　layer　on　MOC　cement　composites　exhibited　high　electrical　conductivity　and　excellent　mechanical　adhesion　to　the　substrate.　Furthermore,　the　rough　copper　patterns　exhibited　self-cleaning　ability　after　superhydrophobic　modification,　which　could　prevent　the　surface　from　being　contaminated.　The　metallized　copper　pattern　could　rapidly　heat　up　when　energised　due　to　the　Joule　heating　effect,　and　it　can　be　applied　for　electric　heating　and　automatic　deicing　in　winter.　In　addition,　a　UV　photodetector　was　fabricated　by　designing　an　interdigital　metallized　pattern　combined　with　the　UV　light　response　characteristics　of　nano-ZnO,　which　has　potential　application　on　intelligent　functional　devices.　©　2022　Elsevier　Ltd
