Cover Image, Volume 140, Issue 31

Wenlong Yang and Yu Wang designed the cover image that showed the interface structure of the polyimide/silica composites. The functional groups on the surface of nanofillers could significantly improve the organic-inorganic interfacial compatibility and the interfacial load transfer efficiency. The static dielectric permittivity of PI-based composites could be elevated by enhancing intrinsic polarization. These results provided an understanding of the atomic-scale interfacial structures, which was beneficial for the design and preparation of the nanocomposites with superior dielectric and mechanical performances.
