Study on Synthesis, Rheological and Electrospinning Functional Materials of Carboxymethyl Cellulose Lithium (CMC-Li)

Abstract: The study on electrospinning of natural polysaccharide polymer to be nano-crystallized is still difficult in the current time. Carboxymethyl cellulose sodium (CMC-Na) was successfully synthesized and acidized to obtain carboxymethyl cellulose hydrogen (CMC-H), and new ionic cellulose ether CMC-Li was synthesized by alkalization, and then we analyzed the difference of structure between the three products. By comparing the rheological measurement and analysis of CMC-Na and CMC-Li, which have different mass fract… Show more

“…This can be used to create fibers with a core-shell morphology that can have various applications in the fields of drug delivery, tissue engineering and wound healing [8][9][10][11]. Here, the application of two different solutions with different polymers and solvents can be used to create products with tailor-made properties if the process is properly controlled [12][13][14]. Polycaprolactone (PCL) is a hydrophobic, semicrystalline polymer, approved from the Food and Drug Administration (FDA) in the United States of America, whose crystallinity depends on its molecular weight.…”

“…CMC-H was burned in a crucible at 700 °C for 30 min, and no residue was found, indi- cating that the acidified CMC-H had no residue of CMC-Na. [24,25] In addition to the characteristic peaks of the common structure in the carboxymethyl cellulose salt, there is a clear difference between the two carboxymethyl cellulose salts at 723.4 cm −1 , which also proves the successful acquisition of CMC-Li, at 1757, 1602, and 1424 cm −1 , which is because the ─C = O bond and ─CO bond coupled to the same carbon atom after the acidic proton of the carboxylic acid group is replaced by Li ion homogenized.…”

“…One of the suggested mechanisms is to use oil–water emulsions as a promising drive fluid to improve oil recovery of viscous oils from the reservoirs . The polymer solution has better viscoelasticity, it can expand the sweep volume and surfactant can improve oil displacement efficiencies, as evidenced by its increasing use. From the combination of flooding pilot tests in Daqing oil fields, the recovery had been increased by over 20% after water flooding…”
