Super long-life supercapacitor electrode materials based on hierarchical porous hollow carbon microcapsules
Remarkable supercapacitor electrodes with a high specific supercapacitance and a super long cycle life
were achieved by using hierarchical porous hollow carbon microcapsules (HPHCMs) as active materials.
HPHCMs were prepared by a facile chemical route based on pyrolysis of a soft sacrificial template
involving a non-crosslinked core of poly(styrene-r-methylacrylic acid) and a crosslinke...

An indole-based conjugated microporous polymer: a new and stable lithium storage anode with high capacity and long life induced by cation–π interactions and a N-rich aromatic structure
An indole-based conjugated microporous polymer, poly-(bisindolylmaleimide) (PBIM), with superior electrochemical performance as an anode material for LIBs has been obtained by FeCl3-promoted oxidative coupling polymerization. Benefiting from reversible cation–π interactions and a unique aromatic structure containing N heteroatoms, the prepared PBIM anode shows high capacity (1172 mA h g-1, 50 ...

氟橡胶密封材料在空气和液压油环境中的老化性能研究
关键字：Fluoroelastomer, Hot air aging, Storage life, Sealing material
航天运载火箭液压系统中应用了大量橡胶密封件，用于防止油、气的泄漏。密封件在液压系统中始终处于压缩状态，随着贮存时间的延长，会产生蠕变和老化，逐步失去密封效能，导致油、气的泄漏。
