Therefore, it is the key breakthrough to develop advanced materials for solving marine fouling problems. Nanomaterials with small dimensions and controlled micro-structure have outstanding antifouling efficiency and great promise for various antifouling fields. Herein, the development of antifouling nanomaterials and technologies in recent years are reviewed for aspects of types of antifouling nanomaterials, technologies of antifouling, and potential application of antifouling. The antifouling nanomaterials are categorized as non-metal-based nanomaterials, metal-based nanomaterials, polymeric nanomaterials, composite nanomaterials, and others. Additionally, the potential applications of antifouling nanomaterials, including marine antifouling, water treatment, and medical antifouling are discussed. Finally, we proposed the perspectives of research and development trends of the antifouling nanomaterials.

The addition of [Pyrr][PTS] into the polymerization medium controls the morphology of PANI without affecting its structure. Moreover, [Pyrr][PTS] promotes a viscous reaction system without the need of an external source. The viscosity of the polymerization system restricts the diffusion of species that leads to the predominance of the homogeneous nucleation mode during the course of polymerization and, thus, nanostructuring of PANI morphology. As for the ionic conductivity, it reflects the mobility of the ions of the polymerization medium and, thus, the way of its interference with the formed PANI that affects the arrangement and the shape of formed PANI fibers. This relationship between PANI morphology and the physicochemical properties, adjusted by adding ionic liquids, of the polymerization medium is prelaminar and promising.
