Polydopamine-based polysaccharide materials for water treatment

Low-cost polysaccharides, such as cellulose, chitosan, chitin and alginate, have come into sight for water treatment. Nevertheless, their treatment efficiency capability are sometimes unsatisfactory because of the lack active sites functionalities. In recent years, more attention has been paid to integration polydopamine (PDA) polysaccharide-based materials develop high-performance products wastewater PDA modification can endow polysaccharides with plentiful functional moieties (including catechol, amine, phenyl groups) binding heavy metals organic pollutants. coatings may increase interfacial stability hydrophilicity oil/water separation. also anchor various catalysts catalytic degradation Furthermore, good light-harvesting photothermal transformation feature available solar-driven purification. This review aims give comprehensive overview on development PDA-based polysaccharide be made cost-effective hydrogels, aerogels, membranes, beads nanocomposites) adsorption pollutants, separation, will valuable information design exploitation in
