Cationized dialdehyde cellulose synthesized with deep eutectic-like solvents: Effects on sheet dewatering and mechanical properties when used as wet-end additive

The ability of cationized dialdehyde cellulose to improve the mechanical properties paper was evaluated. majority additives are synthesized by introducing cationic groups through chemical reactions. Here, were produced in a more environmentally friendly manner use non-toxic and readily biodegradable deep eutectic-like solvent mixtures (DESs). modified cellulose’s characterized FTIR, polarized-light optical microscopy, charge titrations, SEM/EDX. investigated as strength for papermaking. Three different amounts additive (2%, 5%, 10%) added pulp, handsheets studied. Because increasing content can affect dewatering process, capabilities pulps with evaluated Schopper-Riegler (°SR) value, water retention value (WRV), vacuum dewatering. Finally, recyclability DES assessed terms cationization reaction efficiency their effect on properties.
