The emerging aramid-mica nanopapers, composed of aramid nanofibers (ANFs) and mica nanosheets (Mica), exhibit superiority in the field of electrical insulation compared with commercial aramid-mica micropapers. Unfortunately, their mechanical and electrical insulating properties are still less than ideal due to insufficient control of their microstructures. Herein, it is presented that by integrating ANFs and Mica into nacre-like aramid-mica nanopapers with improved structural orderliness, densification, and interlayer interaction, simultaneously improved mechanical and electrical insulating properties are achieved. Their maximum tensile strength and breakdown strength reach approximate to 292 MPa and approximate to 176 kV mm(-1), respectively, which are superior to those of the state-of-the-art ANFs-based nanopapers. Particularly, the aramid-mica nanopapers show high resistance to high-temperature (250-300 degrees C) and oil-bath (100 degrees C) environments commonly involved in practical applications, and can be recycled many times, demonstrating their great potential as high-performance sustainable electrical insulating papers to be applied in advanced electrical equipment.
