Suspensions of Silica Particles Grafted with Concentrated Polymer Brush: A New Family of Colloidal Crystals

Ohno, Kohji, Morinaga, Takashi, Takeno, Satoshi, Tsujii, Yoshinobu, Fukuda, Takeshi·2006·Macromolecules

Abstract

A colloidal crystal was newly identified for a liquid suspension of the hybrid particles having a spherical silica core and a shell of well-defined poly(methyl methacrylate) “concentrated brush”. With increasing particle concentration, the suspension progressed from a (disordered) fluid to a fully crystallized system, going through a narrow crystal/fluid coexisting regime. The crystal had a face-centered cubic structure with a surprisingly large nearest-neighbor interparticle distance, suggesting that the graft chains, highly extended due to the “concentrated brush effect”, exerted a long-range steric interaction. This type of colloidal crystal is new with respect to the origin of long-range interparticle potential and the controllability of many of the system parameters.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
