High-Performance Lignin-Containing Polyurethane Elastomers with Dynamic Covalent Polymer Networks

Liu, Weifeng; Fang, Chang; Wang, Shengyu; Huang, Jinhao; Qiu, Xueqing

High-performance lignin-containing polyurethane elastomers (LPUes) were successfully synthesized via partially substituting petroleum-derived polyols with depolymerized enzymatic hydrolysis lignin (DEL). The influences of DEL on the structure, thermostability, mechanical performance, and thermal reprocessability of LPUes were systematically studied. The tensile strength and toughness of PUes were…

A kind of side-chain type anion exchange membranes (AEMs) with high ionic conductivity and good comprehensive stability was prepared via direct modification of commercial engineering plastic polyketone with diamines through Paal-Knorr reaction and quaternization reaction. It was found that the amount of diamine can effectively tune the microphase morphology and…

CO2 capture with polyamine-based protic ionic liquid functionalized mesoporous silica

Zhang, Wei; Gao, Erhao; Li, Yu; Bernards, Matthew T.; He, Yi; Shi, Yao

A mesoporous silica supported polyamine-based protic ionic liquid (PIL) sorbent has been prepared by impregnating tetraethylenepentammonium nitrate onto the surface of SBA-15. This innovative hybrid adsorbent exhibits an excellent CO2 adsorption rate in the rate-controlling step of 147?×?10?3 mmol g?1 s?0.5, at least threefold better than other IL-functionalized and amine-modified…

High-Performance Organic Electrochemical Transistors Based on Conjugated Polyelectrolyte Copolymers

Schmode, Philip; Ohayon, David; Reichstein, Paul M.; Savva, Achilleas; Inal, Sahika; Thelakkat, Mukundan

A new generation of polythiophene-based polyelectrolytes is reported to address fundamental issues in organic electrochemical transistors (OECTs). In such devices, the semiconductor must be able to transport and store ions and possess simultaneously a very high electronic mobility. For this, the ion-conducting 6-(thiophen-3-yl) hexane-1-sulfonate tetramethylammonium monomer (THS–TMA+) is…

Tuning the photoluminescence and anisotropic structure of PEDOT

Ivanko, Iryna; Pánek, Ji?í; Svoboda, Jan; Zhigunov, Alexander; Tomšík, Elena

In the current work, we study the photoluminescence and anisotropic structure of PEDOT which is obtained in the presence of ions that perturb the water structure (ions in Hofmeister series). The water content in PEDOT has been confirmed by TGA and DSC measurements. The weight loss and heat flux together…

The role of disaccharides for protein–protein interactions – a SANS study

Olsson, Christoffer; Swenson, Jan

The disaccharide trehalose has shown outstanding anti-aggregation properties for proteins, which are highly important for the possibility to treat neurodegenerative diseases, such as Alzheimer’s and Huntington’s disease. However, the role and mechanism of trehalose for such stabilising effects are still largely unknown, partly because a direct structural picture of how…
