Ultra-low dielectric constant silica/ polyimide (SiO2/PI) composite nanofiber membranes are prepared by the combined sol-gel and electrospinning techniques.The emulsion composed of partially hydrolizedtetraethoxysilane (TEOS) and polyamic acid (PAA) is spun to yield the precursor of the SiO2/PI fibers with a core-shell structure due to phase separation.

通过原位聚合,将胺基化改性碳包四氧化三铁(Fe3O4@C-NH2)纳米粒子引入到聚酰亚胺基体中,制备得到一种新颖的、介电性能增强的四氧化三铁(Fe3O4)/聚酰亚胺(PI)复合材料.通过水热反应制备得到Fe3O4,然后再次通过水热反应将交联的葡萄糖包覆到Fe3O4表面得到Fe3O4@C.核壳结构的Fe3O4@C-NH2是通过在碳层上引入氨基得到.
为满足日益增长的保护环境和节约资源的需求,探索生物基弹性体作为下一代的介电弹性体(DEs)是很有必要的.本项研究中,我们采用高介电常数(e r)的生物明胶/甘油(GG)弹性体作为介电弹性体的基体,用天然纤维素纤维中提取的纤维素纳米晶体(CNCs)来提高GG弹性体的力学强度.结果 表明,CNCs的大量羟基破坏了明胶分子之间的氢键,且与明胶分子形成了更强的氢键.CNCs与GG具有良好的界面附着力,从而

如何通过构筑复合材料的空间结构,在获得高介电常数的基础上兼具低介电损耗和低渗流阈值是目前high-k聚合物复合材料研究中的重要课题.本文以多壁碳纳米管(MWCNT)为导体,以酚酞基聚芳醚砜(cPES)/氰酸酯(CE) (w/w=10/90)混合体系为树脂基体,采用两步法制备了MWCNT/CE/10cPES复合材料,系统研究了其介电性能.研究发现,与MWCNT/CE复合材料相比,MWCNT/CE/1
