Lignin-based Foams: Production Process and Characterization

Characterization of Biobased Polyurethane Foams Employing Lignin Fractionated from Microwave Liquefied Switchgrass

Lignin samples fractionated frommicrowave liquefied switchgrass were applied in the preparation of semirigid polyurethane (PU) foamswithout purification.Theobjective of this studywas to elucidate the influence of lignin in the PUmatrix on themorphological, chemical,mechanical, and thermal properties of the PU foams.The scanning electronmicroscopy (SEM) images revealed that lignin with 5 and 10%...

Lignin Depolymerisation under Supercritical Process Conditions for Aromatic Chemicals Production

Valorisation of lignin plays a key role in the further development of biorefinery processes for biofuels and the production of biobased materials from lignocellulosic biomass. Today’s increased demand for alternatives to fossil carbon based products, such as the production of transportation biofuels and bulk “green” chemicals, expands the interest and the need to create added value to the uncon...

Lignin-based Pickering HIPEs for macroporous foams and their enhanced adsorption of copper(II) ions.

Interconnected macroporous foams were synthesized by templating oil-in-water Pickering high internal phase emulsions solely stabilized by lignin particles. They exhibited excellent adsorption capacity for copper(II) ions in aqueous solutions.
