The monomer was functionalized by introducing the thermocrosslinkable benzocyclobutene groups, and its cured product displayed a dielectric constant ( ε ) of 2.59 and a dielectric loss (tan δ) of 5 × 10 −4 at a high frequency of 10 GHz. In contrast, a controlling polymer with methyl side chain exhibited a ε of 2.84 and a tan δ of 1.4 × 10 -3 , respectively. Such data indicate that the long alkyl-side-chains can effectively improve the dielectric properties of the aryl polymers. Moreover, the cured hydrogenated bio-based cardanol also exhibited good hydrophobicity properties with the water absorption of 0.16 % even immersing it in boiling water for 96 h. These results imply that bio-based cardanol is a potential candidate for the preparation of the low-k materials used in microelectronic industry.","PeriodicalId":18477,"journal":{"name":"Materials Today Communications","volume":"50 1","pages":"114139-114139"},"PeriodicalIF":0.0,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147908531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
