Poligromorph Materials: Shape Morphing Functional Polyvinyl Alcohol/Maleic Anhydride Ethylene‐Propylene/Carbon Composites in Aqueous and Hydrocarbon‐Based Media

Advanced Intelligent Systems, EarlyView.
Hygromorphic materials, such as pinecone scales, respond to humidity changes. This study presents poligromorphic composites—composed of carbon fibers (CFs), polyvinyl alcohol (PVA), and maleic anhydride ethylene‐propylene (MA‐EPR)—that react to water, humidity, and hydrocarbons.

Update: Enzymatische Synthese für industrielle Anwendungen

Angewandte Chemie, EarlyView.
Die Biokatalyse hat sich zu einer nachhaltigen und wettbewerbsfähigen Alternative zur herkömmlichen chemischen Synthese entwickelt und ermöglicht die enzymbasierte Herstellung nicht nur von chemischen Grundstoffen, sondern auch von (nicht natürlichen) Aminosäuren, (seltenen) Zuckern und synthetischen Nukleotiden.

Room‐Temperature Material Recycling/Upcycling of Polyamide Waste Enabled by Cosolvent‐Tunable Dissolution Kinetics

Angewandte Chemie International Edition, Accepted Article.
Polyamides (PAs, nylons) are a ubiquitous class of high‐performance plastics used extensively in a wide range of applications. Their high resistance to many common solvents and tendency to hydrolyze in strong acids or bases creates a major hurdle to low‐emissions material recycling (i.e., resource separation and recovery).

Coordinative Ring‐Opening Polymerization of Limonene Carbamate towards Phosgene‐ and Isocyanate‐Free Polyurethane

Angewandte Chemie International Edition, Accepted Article.
This study presents a phosgene‐ and isocyanate‐free route for the synthesis of polyurethanes using (R)‐limonene as a bio‐based starting material. The synthesis of the cyclic limonene‐based carbamate monomer LU is achieved in high yields using dimethyl carbonate as a sustainable, less hazardous phosgene surrogate and is verified by NMR, SC‐XRD, ESI‐MS ...
