摘要 研究缩水甘油基-笼型聚倍半硅氧烷(G-POSS)对环氧树脂(EP)介电性能与热学性能的影响和作用机理。实验制备G-POSS质量分数在0%、0.5%、1%、2%、3%和5%的环氧/POSS复合电介质试样。测试和研究G-POSS质量分数对环氧/POSS复合电介质相对介电常数、交流击穿场强、玻璃化转变温度等的影响。当G-POSS质量分数较低时,环氧/POSS复合电介质性能随G-POSS质量分数增加而不断提高;在G-POSS质量分数达到2%时,复合电介质各项性能均得到较大程度的提升;当继续增加G-POSS质量分数时,环氧/POSS复合电介质的性能开始下降,甚至劣于纯环氧试样。分析认为,G-POSS与环氧基体间形成的大量交联网状结构对环氧/POSS复合电介质性能的影响巨大。

Abstract:In this paper, the effect and mechanism of a new material, G-POSS, on the dielectric and thermal properties of epoxy resin (EP) were studied. The EP/POSS composites with 0wt%, 0.5wt%, 1wt%, 2wt%, 3wt% and 5wt% of G-POSS were fabricated in the experiments. The permittivity, AC breakdown strength and glass transition temperature were measured and analyzed for composites. The performance of the EP/POSS composite is improved with the increase of the G-POSS content when the G-POSS content is low. When the content of G-POSS reaches 2wt%, the performance of the composite has been greatly improved. When the G-POSS continues to increase, the performance of the composite begins to decrease, even inferior to the pristine epoxy resin. It is believed that the formed cross-linking networks in the epoxy matrix due to the G-POSS have a great influence on the performance of EP/POSS composites.
