We present a simple analytical model for the forces that determine jet diameter during electrospinning as function of surface tension, flow rate, and electric current in jet. The predicts existence terminal diameter, beyond which further thinning due to growth whipping instability does not occur. Experimental data various electrospun fibers attest accuracy model.
Electrospinning of nanofibers materials that are difficult to process using conventional techniques is reported. Two fluids electrospun (see Figure) into fibers with core/shell morphology. The "electrospinnable" shell fluid serves as a aid electrospin the core fluid. Three examples illustrated: production diameters less than 100 nm, formed low-molecular-weight polyaniline, and non-blended silk fibers.
Herein, this review article aims to provide a relatively comprehensive summary of research progress in the dissolution and processing cellulose with ionic liquids.
Abstract An iridescent chameleon‐like material that can change its colors under different circumstances is always desired in color‐on‐demand applications. Herein, a strategy based on trichromacy and the dynamically tunable fluorescence resonance energy transfer (FRET) process to design prepare these fluorescent materials proposed. A set of trichromic (red, green, blue), solid are synthesized by covalently attaching spiropyran, fluorescein, pyrene onto cellulose chains independently. After...
An effective method for grafting l-lactide (LA) from unmodified cellulose by ring-opening polymerization (ROP) in homogeneous mild conditions is presented. By using 4-dimethylaminopyridine (DMAP) as an organic catalyst, cellulose-graft-poly(l-lactide) (cellulose-g-PLLA) copolymers with a molar substitution (MSPLLA) of PLLA range 0.99−12.28 were successfully synthesized ionic liquid 1-allyl-3-methylimidazolium chloride (AmimCl) at 80 °C. The amount and length grafted cellulose-g-PLLA...
The polydimethylsiloxane (PDMS) coating penetrated into the underneath ZIF-8 polycrystalline membrane not only blocking inter-crystalline defects but also hindering flexibility of framework, resulting in an unusual and highly desired increase separation selectivity C3H6/C3H8 mixture under high feeding pressures.
Cellulose aerogel membranes (CAMs) are proposed as a matrix for gel polymer electrolyte to the fabrication of lithium-ion batteries (LIBs) with superior thermal stability. The CAMs obtained from cellulose-ionic liquid solution via dissolution-regeneration-supercritical drying route. presence high porosity, nanoporous network structure, and numerous polar hydroxyl groups benefits quick absorption electrolytes gelation improves ionic conductivity gelled CAMs. LIBs assembled display excellent...
Monolithic cellulose aerogels were prepared via a dissolution–regeneration route by dissolving in 1-allyl-3-methylimidazolium chloride (AMIMCl). Using high concentration aqueous AMIMCl solution as the regeneration bath endowed with flexibility and transparency. Possessing homogeneous nanoscale porous morphology, strong have excellent compressive properties, low densities, thermal conductivities.
All-cellulose nanocomposites, with cellulose nanocrystals as the reinforcing phase and regenerated matrix, are prepared by a partial dissolution method in 1-ally-3-methylimidazolium chloride (AmimCl), followed solution casting. The direct images of many undissolved cellulose/AmimCl solutions have been observed clearly conventional transmission electron microscopy (TEM). X-ray diffraction (XRD) also proves that there original I crystals films. nanocomposite films compact, isotropic...
Cellulose–silica composite aerogels were prepared by in situ formation of silica nanoparticles via a two-step sol–gel process cellulose gel, which was dissolving cotton pulp 1-allyl-methylimidazole chloride ionic liquid (AmimCl) and then regenerating from AmimCl/water bath. Related properties investigated with ultraviolet–visible spectrometer, scanning electron microscopy, compression tests, thermogravimetric analysis, ignition tests as well microscale combustion calorimeter. The results...
Organic solid‐state fluorescent materials have exhibited great potential application in optoelectronics, imaging, sensing, and security printing. However, the conventional conjugated luminogens such as perylene pyrene derivatives are not highly recommended for preparation of solid because they always undergo fluorescence self‐quenching state, i.e., aggregation caused quenching (ACQ) phenomenon. Herein, a series with excellent emission been realized via covalently bonding ACQ onto cellulose...
Continuous ZIF-67 polycrystalline membranes with effective propylene/propane separation performances were successfully fabricated through the incorporation of zinc ions into framework. The factor increases from 1.4 for pure membrane to 50.5 90% zinc-substituted membrane.
