In this work, the flocculation behavior and mechanism of chitosan-based graft copolymers with different grafting monomers (i.e. carboxymethyl chitosan-grafted polyacrylamide (CMCP), carboxymethyl chitosan-graft-poly (acrylamide-dimethyl diallyl ammonium chloride) (CMCPD), and chitosan-graft-poly (acrylamide-dimethyl diallyl ammonium chloride) (CPD)) on the kaolinite (001) surface were investigated using molecular dynamics simulations, flocculation experiments and flocs size measurement. The interaction energy calculations revealed that the copolymers exhibited the following order: CPD (− 943.105 kcal/mol) &gt; CMCPD (− 522.812 kcal/mol) &gt; CMCP (− 340.026 kcal/mol). The calculated solvent-accessible surface area (SASA) showed that amphoteric CMCPD exhibited complete extension and unrestricted diffusion in solution, surpassing the capabilities of both CMCP and CPD. The diffusion coefficients of CMCPD, CPD, and CMCP, were determined to be 5.17 × 10^–10 m²/s, 2.68 × 10^–10 m²/s and 4.25 × 10^–10 m²/s, respectively. It can be inferred that the bridging ability of the CMCPD flocculant in solution is directly proportional to its higher diffusion coefficient. However, excessive adsorption of CPD onto kaolinite resulted in a reduction in the bridging capacity of CPD. The simulation results were validated by conducting flocculation experiments, and it was observed that CMCPD, possessing the strongest bridging capability, exhibited a significantly higher settling rate (19.47 m/h) compared to CPD (12.56 m/h) and CMCP (9.81 m/h). The analysis of flocs particle size further confirmed the superior bridging ability of CMCPD, as evidenced by its largest flocs particle size, thereby facilitating rapid settling.

The effect of pH and different gelling agents on the phase behavior and the formation of microemulsion-gels were also explored. The results reveal that the MEs show no significant change in droplet size under high-speed centrifugation, providing great kinetic stability, which enables the MEs to maintain their stability under bumpy and rugged transportation conditions.

We explored the interactions of cetirizine hydrochloride (CTZ) and diphenhydramine hydrochloride (DPC) with mixed micelles composed of sodium dodecyl sulfate (SDS) and sodium dodecylbenzene sulfonate (SDBS). UV-absorbance spectra revealed that drug absorption increased with the mole fraction of SDBS in the micelles, suggesting effective binding. The binding constants (<i>LogK</i>_<i>b</i>) for both drugs were higher in mixed SDS-SDBS micelles than in single-component micelles, with CTZ exhibiting stronger binding due to its electrostatic and hydrophobic interactions. The mean number of drug molecules per micelle (<i>i</i>_<i>o</i>) showed that CTZ occupied micelles more efficiently than DPC, correlating with the higher <i>K</i>_<i>b</i> values observed. The partition coefficients (<i>K</i>_<i>x</i>) from Kawamura’s model further indicated that CTZ had a greater affinity for the micelles compared to DPC. Additionally, dynamic light scattering (DLS) and transmission electron microscopy (TEM) demonstrated that the presence of CTZ and DPC resulted in larger micellar aggregates, with micelle size increasing as the mole fraction of SDBS rose. Molecular docking studies supported these findings, predicting that both drugs interacted electrostatically with the anionic surfactants, with CTZ binding more strongly due to its hydrophobicity and larger aromatic structure. These results provide a deeper understanding of drug-micelle interactions and highlight the role of electrostatic and hydrophobic forces in improving drug delivery systems.
