Green Semi-IPN Hydrogels by Direct Utilization of Crude Wood Hydrolysates
Crude and unmodified acetylated galactoglucomannan containing wood hydrolysate (WH) was directly incorporated into a semi-interpenetrating network (semi-IPN) composed of up to 60% renewable polymers.
Barriers from wood hydrolysate/quaternized cellulose polyelectrolyte complexes
Biobased polyelectrolyte complexes (PECs) were prepared by mixing negatively charged O-acetyl-4-O-methylglucuronoxylan-rich wood hydrolysate (WH) and positively charged quaternized cellulose (QC) in
Impact of Lignin Content on the Properties of Hemicellulose Hydrogels
TLDR
The influence of the purity of hemicellulose and the addition of lignosulfonates to the crosslinking reaction mixture on the mechanical, thermal, and chemical properties of hydrogels was determined.
Facile and Green Approach towards Electrically Conductive Hemicellulose Hydrogels with Tunable Conductivity and Swelling Behavior
A one-pot reaction to synthesize electrically conductive hemicellulose hydrogels (ECHHs) is developed via a facile and green approach in water and at ambient temperature. ECHHs were achieved by
Hemicellulose-Based Polymers Processing and Application
Hemicellulose is the second most abundant biomass in the world. Because of its unique chemical structure, hemicellulose has attracted more and more research and industry application under the
In Situ Synthesis of Magnetic Field-Responsive Hemicellulose Hydrogels for Drug Delivery
TLDR
Magnetic field-responsive hemicellulose hydrogels, prepared using a straightforward one-step process, expand the applications of biomass-derived polysaccharides by combining the renewability of hemiceLLulose and the magnetism of Fe3O4 nanoparticles.
Transfer of Biomatrix/Wood Cell Interactions to Hemicellulose-Based Materials to Control Water Interaction.
TLDR
This Review aims to give a perspective on these issues and demonstrate how the transfer of molecular wood cell interactions into hemicellulose-based materials may offer new design principles for material formulations.

TLDR
A hydrolysate used in the crude state without any membrane filtration performed just as well as upgraded fractions in forming films providing acceptable tensile properties and a good barrier against oxygen permeation.
Biodegradable polymers from renewable sources: rheological characterization of hemicellulose-based hydrogels.
TLDR
Comparisons with pure poly(2-hydroxyethyl methacrylate) hydrogels showed that their behaviors were rather similar, demonstrating that the synthetic procedure made it possible to prepare hemicellulose-based hydrogel systems with properties similar to those of pure poly (2-Hydroxyethyl methamphetamine) Hydrogels.
Wood hydrolysate barriers: performance controlled via selective recovery.
TLDR
The WH in the least upgraded state, the crudest fraction, produced films with the best performance in terms of oxygen permeability and was superior to corresponding films based on highly purified hemicellulose.
