Aqueous colloids with a high concentration of nanoparticles and free steric stabilizers are prospective soft materials, the engineering which is still challenging. Herein, we prepared superparamagnetic very large, up to 1350 g/L 11 nm via Fe2+ Fe3+ coprecipitation, water washing, purification using cation-exchange resin, stabilization monolayer citrate anions (ζ potential diluted dispersions about -35 mV). XRD, XPS, Mössbauer, FTIR spectra elucidated defective reverse spinel structure magnetite/maghemite (Fe3O4/γ-Fe2O3) reduced content cations. The viscosity increases nanoparticle depends also on nature salt, being one order magnitude lower for lithium than sodium potassium as counter-cation. SAXS/USAXS curves show power-law behavior in scattering vector range between 0.1 0.002 nm-1, suggesting that particles interact forming fractal clusters, looser Na+- denser Li+-citrate (fractal dimensions 1.9 2.4, respectively). In parallel, ATR-FTIR found increasing proportions symmetric O-H stretching vibrations ice-like interfacial concentrated colloids. We hypothesize clusters arise due attraction like-charge possibly involving shells hydration counter-cations; overlapping transition continuous non-Newtonian phases seen at vs plots 700-900 g/L. results shed new light nanocolloids pave way their manufacturing tailoring.
