UV-Filtering Cellulose Nanocrystal/Carbon Quantum Dot Composite Films for Light Conversion in Glass Windows

The development of energy-saving materials in buildings based on biomass materials is a general consensus building construction of low-carbon cities. Herein, we reported an effective ultraviolet (UV)-filtered film, composed of carbon quantum dots (CDs) and cellulose nanocrystals (CNC). The results showed that CNC had nanoscale dimensions with a diameter of 20–50 nm and length of 250–450 nm, a high crystallinity index of 84.7%, and enrichment of hydrogen bonds on the surface. The photoluminescence spectra showed that lignin-based carbon quantum dots (CDs) exhibited a long-wavelength red emission (623 nm) and an uncommon narrow emission bandwidth (fwhm <30 nm). In addition, the prepared UV-filtered film had strong mechanical tensile properties, good UV light absorbing capability, and water resistance. The optical test showed that the film also had highly optical transparency (94%) and haze (70%). The excellent light management and conversion function of this film provides a new user experience for soft, uniform, healthy, and comfortable indoor sunlight lighting

Video1_A Superhydrophobic Moso Bamboo Cellulose Nano-Fibril Film Modified by Dopamine Hydrochloride.MP4

The moso bamboo fiber powder was used as raw material to prepare cellulose nano-fibril films, 5% of polyvinyl alcohol solution was used as a structural reinforcement agent, dopamine hydrochloride (DA) was used as a surface adhesive, and hexadecyl trimethoxy silane was used as a surface modifier. The superhydrophobic films were prepared by vacuum filtration and impregnation. The results showed that the water contact angle on the surface of the film could reach 156°. The microstructure and chemical composition of the film surface was further studied by scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FTIR), and roughness measurement The scanning electron microscopy images showed that the nanofibers on the surface of Cellulose nanofibers film were arranged and randomly distributed, thus forming a dense network interwoven structure. In PDA hydrophobic modification solution, an Hexadecyltrimethoxysilane was hydrolyzed to a hexadecyl silanol to obtain the polar terminal hydroxyl of Hexadecyl silanol molecule. The -OCH3 terminal group of HDTMS reacted with hydroxyl/H2O to form a silanol (Si-OH) bond and further condensed to form a Si-O-Si network. In addition, due to the hydrophilicity of the surface of the nano cellulose film, a large amount of—OH was adsorbed on the surface of the nano cellulose film, resulted in the chemical connection between cetyl groups, thus realized the grafting of cetyl long-chain alkyl groups onto the fibers of the nano cellulose film.The film showed good self-cleaning and waterproof properties, which can be widely used in wet environment packaging and building.</p

Regioselective Radical-Relay Sulfonylation/Cyclization Protocol to Sulfonylated Pyrrolidones under Transition-Metal-Free Conditions

A simple and low-cost tandem sulfonylation/cyclization of 1,5-diene, aryldiazonium salt, and DABCO·(SO2)2 is disclosed. This base-promoted multicomponent reaction can provide a “green” and economic synthesis of sulfonylated pyrrolidones under transition-metal-free and moisture/oxygen-insensitive reaction conditions, thus delivering a wide range of sulfonylated pyrrolidones in moderate to high yields with excellent functional group compatibility. A plausible mechanism involving a radical process is proposed, which demonstrates highly chemoselective trapping of the aryl radical with “SO2” species, and a regioselective sulfonylation/cyclization protocol in this reaction

Construction and Application of Biobased PDES Ionic Gels with a Soft–Hard Segment

Ionic gels composed of bio-based precursors, such as itaconic acid (IA), are promising for flexible materials. However, IA, a bio-derived monomer for free radical polymerization, faces the challenge of spatial hindrance. Herein, we introduced a choline chloride (ChCl)–IA deep eutectic system to prepare poly deep eutectic solvents (PDESs) as the soft segment and acrylamide (AM) as the precursor of the polymer hard segment to form P­(IA-co-AM) ionic gel, driven by hydrogen bonding. Molecular dynamics (MD) well confirms that poly AM (PAM) and ChCl can defeat the spatial resistance caused by −CC and −COOH of IA. Furthermore, the hard segment PAM provided enhanced strength of the ionic gel trough 21 to 850 kPa. The free volume fraction then demonstrated that the P­(IA1-co-AM1.1) ionic gel had both a porous mesh structure and electrical conductivity. This further confirmed that the P­(IA-co-AM) ionic gel with high tensile strength, light transmittance, and excellent stability could sense the bending of the human finger and wrist with a gauge factor of 1.82
