Bioinspired design and assembly of platelet reinforced polymer films with enhanced absorption properties

Bioinspired by the natural structural composites, we selectively synthesized CuS hexagonal nanoplatelets by a simple wet chemical method; and a novel approach was also developed to synthesize the brick-mortar structure CuS/PVDF nanocomposite films by self-assembly of CuS hexagonal platelets building blocks. The mechanics of the composites can increase by 50%, and the absorption peak also can reach -29.66 dB at 10.90 GHz with low filler content, the enhanced mechanism was also explained.
