The molecular simulation software was firstly applied to analyze the adsorption of sulfomethylated lignin (SAL) on dye surfaces. Then, SALs with different sulfonic group contents were prepared and characterized by FTIR, NMR, EA GPC measurements using alkali (AL) as raw materials sodium sulfite sulfonating agents. Next, SAL1.53 determined optimum dispersant TSI, particle size thermal storage stability measurements, which had smallest 173 nm highest stability, comparable commercial Reax 85A basically satisfying requirement nano disperse dyes used in digital printing technology. QCM, AFM zeta potential results indicated that content SAL increased, mass, rigidity adsorbed layer, force absolute value all showed a gradually increasing tendency due an enhanced hydrophilicity, thus decreased intermolecular agglomeration increased chain stretching degree. A maximum observed for SAL1.53. This research not only provided novel approach preparation high-performance dispersants dyes, but also would broaden high value-added industrial applications biomass into dyeing field.

The development of next-generation sustainable energy storage devices is attracting a lot attention. This study explores the potential use lignin, biopolymer typically considered byproduct paper and pulp industry, as starting material for producing hydrogels through chemical crosslinking. resulting are then evaluated their efficacy precursors electrolyte electrode preparation in supercapacitor. Several concentrations lignin crosslinker were to determine optimal conditions hydrogel electrolytes. optimised exhibited excellent properties, including high swelling capacity, an interconnected macroporous morphology, structural integrity. carbonisation lyophilised produced lignin-derived carbon materials with tailored nanoporous honeycomb-like structures. integration chemically crosslinked electrolytes electrodes resulted supercapacitor superior electrochemical properties. all-lignin-based supercapacitors demonstrated capacitance 40.7 F/g at 0.5 A/g current density, capacity retention 60% higher densities. results this highlight promise lignin-based both creation environmentally sustainable, high-performance supercapacitors.
