When a nuclear power plant is operated in a high-temperature environment, its critical components are subjected to creep-fatigue interaction. In order to study the creep-fatigue performance of TP321 austenitic stainless steel at high temperatures, creep-fatigue tests are conducted and combine with microstructure inspection to analyze the effects of temperature, holding time and strain amplitude on the deformation and damage behavior of TP321 austenitic stainless steel. Then, three different life prediction models are used to predict the life of the creep-fatigue tests. The results show that increasing the test temperature, holding time and strain amplitude decreases the creep-fatigue life of the material. A tendency for cracks and cavities to promote each other’s expansion is observed, which is an important reason for the decrease in creep-fatigue life. Of the three life prediction models, the modified strain energy density (MSEDE) exhaustion model gives the most accurate lifespan prediction.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 12","pages":"5603 - 5622"},"PeriodicalIF":3.5,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a new class of microencapsulated graphene-reinforced silicone elastomer foam composite with excellent dielectric properties is presented. The silicone elastomer/graphene composite was prepared through foaming. The interfacial compatibility between silicone elastomer and graphene was enhanced by microencapsulated graphene, with graphene as the core and MF as the shell, through in-situ grafting reactions. The best microencapsulated graphene with a “salt-like” substance was achieved at a dispersing power of 840 W, a ratio of graphene to emulsifier of 1:100, and a mass ratio of graphene to wall material MF of 1:10. The silicone elastomer foam composite with optimized microencapsulated graphene content displays a dielectric constant of 27.26 @1000 Hz ~ 10 MHz with a significantly improved dielectric loss of @1000 Hz ~ 10 MHz, which is 2.45 times greater than the dielectric constant of graphene/silicone elastomer composite. This performance originates from the synergistic effect of micropore and microencapsulated. This interaction reaches its peak when the content of microencapsulated graphene is increased to 2.0 wt%, resulting in a dielectric constant of 48.26. The optimization of high-electric-constant foam composite will have far-reaching impacts on the sustainable energy and will be an important research topic in the near future.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 12","pages":"5381 - 5398"},"PeriodicalIF":3.5,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These excellent performances originate from the enrichment layer in PVC gel formed by the migration of plasticizers and charge transfer. The intermolecular interactions between plasticizers and PVC molecular chains are crucial in plasticizers migration, but the effect of these factors on actuator’s performance is still unclear. In this study, the effects of types of plasticizes with varying molecular volumes on the actuation performance of PVC gel actuators were systematically investigated using experiments and simulations. The network structure of PVC gels typically consists of a primary network formed by physical entanglements and microcrystals and a secondary network constructed by intermolecular interactions between primary network and plasticizers, including hydrogen bonds and van der Waals forces. The experimental and simulation results indicate that intermolecular interactions significantly influence the migration rate of plasticizers within the PVC gel. The PVC gel actuators prepared with large-volume plasticizers containing a benzene ring structure exhibit the strongest intermolecular interactions. When subjected to an applied stimulus voltage of 800 V, the actuator made with benzene-ring-based plasticizers achieves a maximum displacement of only 23%, along with a relatively longer response time compared to the gel incorporating linear plasticizers. These results provide valuable insights into the relationship between the internal structure and actuation performance of PVC gels for their potential applications in robotic devices and medical assistive equipment.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 12","pages":"5634 - 5647"},"PeriodicalIF":3.5,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pristine carbon cloth was doubly activated by Hummers method and electrochemical treatment for the improvement of hydrophilicity and capacitance.
