Crosslinked polymeric networks of TiO2-polymer composites: a comprehensive review

The crosslinked network of TiO2-organic polymer composites has gained considerable attention over the past few years. The low band gap of TiO2 particles and the stimuli-responsive behavior of organic polymers make these composites suitable for a wide range of applications in biomedicine, environmental fields, and catalysis. Diverse morphologies and structures of TiO2-polymer composites (TPCs) are documented in the available literature, where the specific architecture of these composites intensely influences their efficiency in various applications. Consequently, a particular shaped TPC is carefully designed to suit specific purposes. This comprehensive review describes the classifications, synthetic approaches, characterizations, and applications of TiO2 nanoparticles decorated in crosslinked organic polymers. It delves into the biomedical, catalytic, adsorption, and environmental applications of these TiO2-polymer composites. The review takes a tutorial approach, systematically exploring and clarifying the applications of TiO2-polymer composites, offering a comprehensive understanding of their different capabilities and uses.
