Figure

Fig. 1. Schematic representation of the stabilization of colloidal particles. a) Colloidal particles agglomerate in water, b) Colloidal particles stabilized in water by a polymer.
Fig. 2. Schematic representation of the coarse-graining of a water molecule. In this case, ρ ¼ 3 and N m = 6, the cut-off distance r c is therefore equal to the length of one side of the cubic cell.
Fig. 3. Coarse-grain method; molecules and monomer conversion into beads for water (W), Polyvinylpyrrolidone (PVP), Polyethylene glycol400 (PEG), Microcrystalline cellulose (MCC), Hydroxypropyl-methylcellulose (HPMC) and Stearic acid (SA).
Fig. 5. Snapshots of DPD simulation at equilibrium state of HPMC-SA (10%–10% (w/w)) mixture in water under different amounts of SA, HPMC: Hydroxypropyl-methylcellulose, SA: Stearic acid.
