Current efforts to improve radiation resistance rely on the addition of antiradiation agents, however, the effects of the components and microstructures of NR itself on radiation resistance remain unclear. In this study, we compared the composition and structure differences of four typical commercially used NR materials and investigated their effects on gamma radiation resistance. Furthermore, we examined the impact of non-rubber components (NRC) in NR on radiation resistance using deproteinized and dephosphorylated NR model samples. Our results revealed that NRC, such as proteins and phospholipids can enhance the strength of natural rubber before radiation exposure. However, after the removal of NRC, the samples exhibited improved mechanical stability under irradiation. Additionally, the ash content in NR could also influence the radiation resistance, as metal ions may react with the active centers produced by radiation, thereby enhancing the radiation resistance of the rubber. This work identifies the effect of non-rubber components in NR on radiation resistance and may serve as a reference for screening and developing radiation-resistant NR materials.</p></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"43 7","pages":"1190 - 1199"},"PeriodicalIF":4.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145168396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among various active pillar structures, liquid crystal elastomer (LCE) pillar arrays are capable of exhibiting significant and reversible anisotropic deformation under cyclic heating and cooling, showing great potential in tunable adhesion, soft robots, and biomedical devices. However, scaling up LCE pillar manufacturing remains challenging, limiting its practical applications. In this work, a solvent-free LCE resin is developed with unique features including simple operating procedure, short fabrication time, and tunable responsive temperature, enabling rapid and large-scale production of LCE pillar arrays. The LCE resin allows for the preparation of complex 3D shapes in addition to film or specimen. The fabrication time can be as short as 4 h, without the need to evaporate solvent. Moreover, the LCE resins can be adjusted with a variable phase transition temperature range from 49.4 °C to 97.7 °C by incorporating non-liquid crystal acrylate chains. The resulting active pillar array structure can undertake sequential actuation upon heating with the tunable actuation temperature. Finally, the application of these pillar arrays in multi-level information encryption is demonstrated.
