Preparation and plasticizing mechanism of deep eutectic solvent/lignin

In contrast to the CS/lignin-LA and CS/lignin-G film, the tensile strength and elongation at break of CS/lignin-U increased upon increasing the lignin content. More specifically, compared to the composite film based on CC-U (DES) alone (tensile strength = 12.0 MPa), a tensile strength of 21.2 MPa was achieved for CS/lignin-U, while the elongation at break increased from 43.4 to 55.9 %.

Lignin-based polymers and nanomaterials

As the primary renewable source of aromatic molecules, lignin can be depolymerized to industrial chemicals referred to as BTX (benzene, toluene, xylene), drop-in transportation fuels compatible with existing internal combustion engines, and specialty chemicals, typically at high temperature, high pressure, and in the presence of catalysts [ 7, 8...

Frontiers | Chemical Modification of Plasticized Lignins Using Reactive

Lignins are a polymeric form of variously methoxy-substituted phenylpropane monomeric units. Due to its general abundance (up to 20¨C30% in hardwood) and its slow biodegradability, lignin is likely to be one of the most abundant biopolymers on earth ( Smolarski, 2012 ).

Thermoplastic Starch/Ternary Deep Eutectic Solvent/Lignin Materials

The goal of the work was to prepare thermoplastic starch (TPS), for the first time plasticized with ternary deep eutectic solvents (DESs) based on urea/resorcinol/choline chloride (URCC) in a 2:1:1 molar ratio and enriched with lignin as an environmentally friendly functional alternative for agricultural plastics. Potato starch was effectively modified with DES via twin-screw extrusion in the

Synthesis of Lignosulfonate-Based Dispersants for Application

Abstract. Lignosulfonates (LS) are products from the sulfite pulping process that could be applied as renewable environmentally-friendly polymeric surfactants. Being widely used as plasticizers and water-reducing admixtures in concrete formulations LS compete in the market with petroleum-based superplasticizers, such as naphthalene sulfonate
