Abstract

Cellulose, chitin, and composite 3D hydrogels and membranes were fabricated without any chemical modification from high-molecular-weight chitin and cellulose-rich material (CRM) extracted from shrimp shell or pine wood, respectively, using the ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate ([C2mim][OAc]). The hydrogels were prepared by redissolution of the extracted biopolymers in the same IL, or in a one-pot process directly from a solution of the biomass after extraction, followed by molding/gelation (“3D gels”) or casting (membranes), and then washing. For comparison, the preparation of gels was attempted using commercial microcrystalline cellulose or chitin. From all of the sources, the regenerated CRM or chitin required significantly lower load. Hydrogels were also converted to aerogels via transformation to alcogels and then Sc-CO2 drying, giving materials of low density, high porosity, favorable compressibility, high water uptake, and moderate antioxidant activity. Air-dried membranes were dense, of high tensile strength, and exhibited high water-vapor transmission.

In Search of Stronger/Cheaper Chitin Nanofibers through Electrospinning of Chitin–Cellulose Composites Using an Ionic Liquid Platform

Journal Article Shamshina, Julia L. ; Zavgorodnya, Oleksandra ; Choudhary, Hemant ; ... - ACS Sustainable Chemistry & Engineering

The ability of the ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate ([C2mim][OAc]) to solubilize natural biopolymers (e.g., chitin and cellulose) without any chemical modification has been used to develop a one-pot process to prepare a spinning dope by extracting chitin from shrimp shell, codissolving microcrystalline cellulose (MCC, DP = 270), and electrospinning nanomats from shrimp shell-extract/MCC solutions. The resulting spinning dopes were prepared with optimal viscosity of 380 to 900 cP, and conductivity and surface tension of ~2.8 mS/cm and ~36 dyn/cm, respectively; however, nanofibers could only be prepared when the chitin/MCC ratios in SS-extract/ MCC solution were between 9/1 and 6/4.more »« less

Comparison of Hydrogels Prepared with Ionic-Liquid-Isolated vs Commercial Chitin and Cellulose

Journal Article Shen, Xiaoping ; Shamshina, Julia L. ; Berton, Paula ; ... - ACS Sustainable Chemistry & Engineering

Physical and/or covalently linked (chemical) hydrogels were prepared from chitin and cellulose extracted with ionic liquid from shrimp shells and wood biomass, respectively, and compared with hydrogels prepared from commercially available biopolymers, practical grade chitin, and microcrystalline cellulose. The highly porous aerogels were formed by initial dissolution of the biopolymers in NaOH/urea aqueous systems using freeze/thaw cycles, followed by thermal treatment (with or without epichlorohydrin as a cross-linker) and supercritical CO2 drying. The ionic-liquid-extracted cellulose pulp and chitin, as well as practical grade chitin could form both stable physical and chemical hydrogels, whereas biopolymers of lower apparent molecular weight suchmore »« less

Chitin extracted from various biomass sources: It's not the same

Journal Article Achinivu, Ezinne C. ; Shamshina, Julia L. ; Rogers, Robin D. - Fluid Phase Equilibria

Here this study demonstrates the use of ionic liquids to successfully extract chitin from different biomass sources and the utilization of the resulting chitins to prepare monofilament fibers. Chitin was extracted from five different biomass sources (processed and raw shrimp shell, crab and lobster shell, and fly larvae) using the ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate ([C₂mim][OAc]). While processed and raw shrimp shell yielded chitin of high purity in quantitative yield, crab and lobster shell resulted in lower yields of chitin. Fly larva provided chitin severely contaminated with proteins. Each extracted chitin was re-dissolved in the same IL and dry wetmore »« less

Pulping of Crustacean Waste Using Ionic Liquids: To Extract or Not To Extract

Journal Article Shamshina, J. L. ; Barber, P. S. ; Gurau, G. ; ... - ACS Sustainable Chemistry & Engineering

Ionic liquids (ILs), such as hydroxyammonium acetate ([NH3OH][OAc]), can reactively demineralize and remove proteins from shrimp shells in an efficient one-pot pulping process, thus allowing the isolation of native chitin with >80% purity and a high degree of acetylation and crystallinity. Compared to a previously reported IL extraction using 1-ethyl-3 methylimidazolium acetate, [C2mim][OAc], these less expensive ILs can achieve comparable chitin yields and purity, at up to ten times the biomass loading, although potentially result in lower molecular weight (MW) chitin. Because the IL is not recovered or recycled, the cost can additionally be further reduced by the sequential additionmore »« less

Ionic Liquid Platform for Spinning Composite Chitin–Poly(lactic acid) Fibers

Journal Article Shamshina, Julia L. ; Zavgorodnya, Oleksandra ; Berton, Paula ; ... - ACS Sustainable Chemistry & Engineering

In the design of stronger chitin fibers reinforced with poly(lactic acid) (PLA), an ionic-liquid-based (IL-based) approach was developed in which both polymers were codissolved in an 1-ethyl-3-methylimidazolium acetate ([C₂mim][OAc]) and wet-jet spun into composite fibers. Chitin, directly extracted from shrimp shell, had a solubility in the IL of 2.75 wt %, while PLA of MW 700 000 g/mol had a solubility of 49 wt %. Keeping the IL saturated in chitin, homogeneous solutions of chitin and PLA could be obtained up to 27 wt % (relative to the IL) PLA. Spinning dopes were prepared by maintaining the chitin concentration relativemore »« less
