This was achieved by inducing a thiol‐ene click reaction between surface ligands containing carbon–carbon double bonds and the cross‐linker pentaerythritol tetrakis (3‐mercaptopropionate) (PTMP) via plasma irradiation. The results demonstrate that argon plasma irradiation can initiate the thiol‐ene click reaction, while also causing the carbon–carbon double bonds in the ligand to undergo cross‐linking. The polymerization of the ligands leads to the encapsulation of the NPLs within the polymer matrix, allowing for excellent stability performance.","PeriodicalId":20135,"journal":{"name":"Plasma Processes and Polymers","volume":"22 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147896887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
