Molecules, Journal Year: 2025, Volume and Issue: 30(7), P. 1610 - 1610

Published: April 4, 2025

Cellulose ethers (CEs), synthesized through the etherification of cellulose, have emerged as indispensable “green additives” in our modern industries, earning moniker industrial “monosodium glutamate” due to their unparalleled multifunctionality. Unlike traditional petroleum-based modifiers, CEs offer a unique combination renewability, low toxicity, and tunable properties (e.g., water retention, thickening, stimuli-responsiveness), making them pivotal for advancing sustainable construction practices. This review presents an overview preparation methods various applications especially concrete mortars well corresponding mechanisms. We systematically analyze methodologies (homogeneous vs. heterogeneous processes) highlight effect molecular determinants (degree substitution, weight, functional groups) on performances CEs. can enhance workability other primarily by acting water-retaining thickening agents mitigate rapid loss, improve hydration efficiency cohesion. The effects delay microstructure are also analyzed highlighted. Beyond construction, we reviewed current emerging CE biomedicine, tissue-engineering, petroleum industry food engineering, highlighting cross-disciplinary potential. provides some insights into structure–property–application relationships brief historical developments, offering guidance optimizing utilizations

The applications of cellulose ethers in the petroleum industry represent various limitations maintaining their rheological properties with an increase both concentration and temperature. This paper proposed a new method to improve hydroxyethyl methyl (HEMC) by incorporating diethyl carbonate (DEC) as transesterification agent alkali base solutions. Fourier transform infrared (FTIR) analysis confirmed grafting composites onto HEMC surface. addition sodium hydroxide (NaOH) improved stability polymeric solution observed from ζ-potential measurement. Shear viscosity frequency sweep experiments were conducted at concentrations 0.25–1 wt % ambient elevated temperatures ranging 80–110 °C using rheometer. In results, specific times indicated activation DEC through saponification reactions All solutions exhibited shear-thinning behavior fitted well Cross model. NaOH-based modified low shear compared DEC-HEMC However, 110 °C, its exceeded that due DEC. analysis, loss modulus (G″) was greater than storage (G′) lower frequencies vice versa higher frequencies. signifies viscoelastic 0.50 concentrations. flow point (G′ = G″) shifted frequency, indicating increasing dominance elastic rising At viscous behavior, confirming solution’s thermal flowability. conclusion, found be effective controlling under conditions, enhancing solubility, improving stability. composite could play significant role optimizing fluid performance challenging wellbore conditions.
