“…As a necessary complement to experimental work, MD simulation of rational simplified model systems can be used to identify the adsorption mode of dispersants on coal particles. [18][19][20][21] Figure 10 depicts the stable adsorption configuration of PC molecules on coal particles. To directly observe the adsorption state, a single PC molecule is selected from the adsorbed PC molecules to demonstrate the adsorption configuration and interaction with coal particles from two different perspectives.…”

“…Recently, many researchers have also studied adsorption behavior by combining molecular dynamics (MD) simulation and experiments, which had improved our understanding of the adsorption behavior of dispersants or surfactants on coal particles from both a macro and micro perspective. [18][19][20][21] This approach means that direct evidence of the adsorption configuration, adsorption functional groups, and adsorption mode of dispersant molecules can be obtained, which is significant for revealing the adsorption mechanisms of dispersants. However, very little literature has been reported on the MD simulation of PC adsorption behavior on coal particles.…”

As a novel form of carboxylate comb‐like copolymers, SAM‐(m)PEG was prepared by polymerizing styrene (S), acrylic (A), and maleic anhydride (M) to obtain a random copolymer labeled SAM. SAM was then esterified using either polyethylene glycol (PEG) or methyl PEG (mPEG), a waterborne polymer dispersant for dispersing and stabilizing C.I. Pigment Yellow 180 (PY 180). The structures of SAM‐(m)PEG and the ground suspension of PY 180 were characterized by Fourier transform infrared (FT‐IR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, scanning electron microscopy (SEM), a nanoparticle size analysis, and viscometry. The effects of different branch chains, synthetic formulas, and grinding conditions on the dispersibility of SAM‐(m)PEG were evaluated. In addition, the optical properties of the pigments were investigated after ultrafine grinding. The adsorption mechanism between the SAM‐(m)PEG dispersants and PY 180 particles is also discussed. SAM‐PEG6002 outperformed the other SAM‐(m)PEG dispersants owing to its excellent dispersion and stability. When used as the dispersant, the average particle size (Z‐average) of PY 180 after grinding was 264.6 nm, and the particle size distribution became narrow (PDI=0.089). Moreover, SAM‐PEG6002 effectively maintained the color performance of the pigment, and the product was successfully applied to the pigment coating. Therefore, SAM‐PEG6002 is an effective waterborne polymer dispersant for organic pigments.
