Sustainable Chitin Nanofibrils Provide Outstanding Flame-Retardant Nanopapers

Read the full article here: Biomacromolecules, 2019, DOI: 10.1021/acs.biomac.8b01766 Sustainable polysaccharides nanofibrils formed from chitin or cellulose are emerging biobased nanomaterials for advanced materials requiring high mechanical performance, barrier properties, for bioactive materials or other functionalities. Here, we demonstrate a single-step, waterborne approach to prepare additive-free flame-retardant and self-extinguishing, mechanical high-performance nanopapers based purely on surface-deacetylated chitin nanofibrils (ChNFs). We show that the flammability can be critically reduced by exchanging the counterions, e.g. to the phosphate type, using the respective acid providing

Vitrimer Chemistry Meets Cellulose Nanofibrils: Bioinspired Nanopapers with High Water Resistance an

Read the full article here: Biomacromolecules, 2019, DOI: 10.1021/acs.biomac.8b01659 Nanopapers containing cellulose nanofibrils (CNFs) are an emerging and sustainable class of high performance materials. The diversification and improvement of the mechanical and functional property space critically depend on integration of CNFs with rationally designed, tailor-made polymers following bioinspired nanocomposite designs. Here we combine for the first time CNFs with colloidal dispersions of vitrimer nanoparticles (VP) into mechanically coherent nanopaper materials. Vitrimers are permanently cross-linked polymer networks that undergo temperature-induced bond shuffling through an associative mecha

Raising the Bar in Aromatic Donor–Acceptor Interactions with Cyclic Trinuclear Gold(I) Complexes as

Read the full paper here: J. Am. Chem. Soc., 2018, 140, 17932. Aromatic donor–acceptor interactions are of high importance in supramolecular chemistry, materials science and biology. Compared to other noncovalent interactions, such as hydrogen bonding, the binding is often weak. Here we show that strong donor–acceptor interactions between planar aromatics with binding free energies down to −10.1 kcal mol–1 and association constants of up to 2.34 × 107 L mol–1 for 1:1 complexes can be realized using cyclic trinuclear complexes of gold(I) with pyridinate, imidazolate, or carbeniate ligands. Data were obtained through NMR and UV/vis absorption spectroscopic studies and supported by quantum chem
