“…Over the years, researchers have diligently explored various solvents in an attempt to overcome the solubility issues of chitin. Notable examples include strong acidic solution, dimethylacetamide (DMAc)-LiCl mixtures, and ionic liquids . Each of these solvents has exhibited varying degrees of success in dissolving chitin, providing viable avenues for further processing and utilization.…”

The exigency within the textile industry for molded fibers has become increasingly pronounced, owing to the coveted attributes inherent in planar fiber products, namely, their luxuriant tactile quality, ethereal weightiness, and avant-garde allure. In this investigation, we propose a pioneering methodology for the synthesis of planar chitin fibers, diverging from the conventional paradigm of spinneret design for fiber shaping. Analytical methodologies, encompassing Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and optical microscopy, were judiciously harnessed to unravel the intricacies of the fiber formation process. By subjecting chitin fibers to coagulation baths infused with phytic acid, a stratified dermalcore architecture was engendered, endowing the fibers with remarkable malleability under exogenic forces, thereby culminating in the homogeneous production of planar chitin fibers. Thorough scrutiny through optical microscopy and cross-sectional analysis substantiates the efficacy of this innovative approach. These revelations not only bestow invaluable insights into the fabrication of planar fibers but also broaden the horizons of potential chitin applications across multifarious domains.

“…In order to diminish the crystalline nature of chitin, several aqueous as well as non-aqueous solvent media have been used for chitin pretreatment, including alkali aqueous solvents, 23,24 inorganic salt aqueous solvents, ionic liquids (IL), deep eutectic solvents (DES), etc. 13,25 Out of these studied solvent systems, IL gained considerable attention for dissolution and derivatization of chitin. Generally being liquids below 100 °C, ILs are special non-aqueous solvent media commonly composed of an organic cation and an organic/inorganic anion.…”

“…However, as a general definition, this review will be concerned with biopolymers in the sense of those materials which are biosynthesized in the cells of living organisms either through natural or man-made processes. Broadly, biopolymers of interest to industrial and academic materials researchers can be divided into four categories, based on their primary structure: polysaccharides (e.g., starch, [2][3][4][5] cellulose, [6][7][8][9][10][11] alginate, [12,13] chitin [14][15][16][17][18] and its derivative chitosan, [19][20][21][22][23][24][25] Fig. 1a), structural proteins (collagen, [26][27][28][29] fibroin, [30][31][32][33] zein, [34][35][36][37][38] Fig.…”

Advances in continuous polymer analysis in flow with application towards biopolymers

Biopolymers, polymers derived from renewable biomass sources, have gained increasing attention in recent years due to their potential to replace traditional petroleum-based polymers in a range of applications. Among the many advantages of biopolymers can be included their biocompatibility, excellent mechanical properties, and availability from renewable feedstock. However, the development of biopolymers has been limited by a lack of understanding of their properties and processing behaviours. Continuous analysis techniques have the potential to hasten progress in this area by providing real-time insights into the properties and processing of biopolymers. Significant research in polymer chemistry has focused on petroleum-derived polymers and has thus provided a wealth of synthetic and analytical methodologies which may be applied to the biopolymer field. Of particular note is the application of flow technology in polymer science and its implications for accelerating progress towards more sustainable and environmentally friendly alternatives to traditional petroleum-based polymers. In this mini review we have outlined several of the most prominent use cases for biopolymers along with the current state-of-the art in continuous analysis of polymers in flow, including defining and differentiating atline, inline, online and offline analysis. We have found several examples for continuous flow analysis which have direct application to the biopolymer field, and we demonstrate an atline continuous polymer analysis method using size exclusion chromatography.

Comprehensive review on pre-treatment of native, crystalline chitin using non-toxic and mechanical processes in preparation for biomaterial applications

Abstract: Chitin forms an intricate and exceptionally stable 3D network in crustacean cuticles. Dissolution of purified chitin without derivatization or damage to its native structure is challenging and recent advances are presented in this review.
