Herein, a structural bionics coating was designed and fabricated on the surface of CL-20 to enhance the thermal safety of CL-20-based PBX. The film was composed of hollow fiber@desensitizer and its performances were recorded by SEM, XPS, TG-DSC, XRD, mechanical sensitivity tester, slow cook-off tester and ignition tester, respectively. The morphology and surface performance showed that CL-20 was completely coated by composite film. Notably, the XRD results provide crucial safety assurance for the preparation process. The aqueous polyurethane emulsion (ATPU)@TiO<sub>2</sub> nanotube film endowed the <em>T</em><sub>p0</sub> and <em>T</em><sub>b</sub> of CL-20 from 218.15℃ and 220.27℃ up to 228.38℃ and 230.92℃, respectively. Meanwhile, the thermal respond reaction of CL-20-based PBX charge occurred at more than 232℃ during slow cook-off heating. These results indicated that the thermal stability of CL-20 was significantly improved. Most importantly, the microcrystalline wax (MW)@multiwalled carbon nanotube (MNCNTs) film brought mechanical critical load of CL-20 from 60 N and 3.5 J to 288 N and 14.6 J, respectively. This improvement allows for the handling of composite explosives using conventional protocols. The ATPU@MNCNTs also increased friction critical load of CL-20 up to the level of WO<sub>3</sub>/Al nanothermite (360 N). In ignition testing, the composite particle underwent rapid thermal decomposition, emitting yellow smoke without combustion. Among the particles, H-3# exhibited the slowest decomposition rate. These findings could offer valuable insights for the broad application of CL-20.</div></div>","PeriodicalId":273,"journal":{"name":"Chemical Physics Letters","volume":"858 ","pages":"Article 141747"},"PeriodicalIF":2.8,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142655880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
