  • Patent number: 11897884
    Abstract: This invention is directed to an aromatic material based free-standing film, a hybrid of organic crystalline materials and inorganic carbon nanomaterials, process of preparation and uses thereof. The film, which comprises a fibrous organic nanocrystals of an aromatic material, is mechanically and thermally stable. This film is optionally reinforced by hybridization with a reinforcement material, such as carbon nanotube, carbon material, a polysaccharide, a nanoclay a metal, metal alloy, or an organic polymer. The hybrid film of organic nanocrystals and carbon nanotubes (ONC/CNT) has high conductivity and high thermal stability. The films or hybrids of this invention are used as microfiltration membranes for various materials, in electrodes or perovskite solar cells.
