This article proposes a method for obtaining stable hydrophobic inhibitor dispersions, where the micelle core contains a hydrophobic solvent, a corrosion inhibitor and an organosilane. Such compositions can be used as polymer-type corrosion inhibitors for low-carbon steel. Using electrochemical methods, corrosion tests and X-ray photoelectron spectroscopy, features of the formation of polymeric layers of hydrophobic organosilicon dispersions were studied.

<p>Polyelectrolyte complex micelles (PCMs) are widely used in the delivery of hydrophilic payloads. Their attractive features include an ability to tune physical attributes, which are strongly dependent on the size and chemical structure of each polymer block. Neutral blocks drive nanoscale phase separation while charged blocks control micelle core size and stability. An understanding of physical property behavior controlled by block size is crucial when designing for use in dynamic or biological environments and provides a greater understanding of the physics of polyelectrolyte assembly. In this work, we use small angle x-ray scattering, and light scattering to determine precise scaling behaviors of physical micelle parameters for commonly used polyelectrolytes. We then compare our results to accumulated published data and theory to show strong agreement, suggesting these laws are universal for PCMs.</p>

Abstract The discovery of Frank-Kasper (FK) phase in block copolymer (bcp) has prompted the progress of the field of soft quasicrystals. In principle, the formation of FK phase from the supercooled liquid phase of the bcp micelles should involve the mass transport of constituent molecules to transform the unimodal distribution of micelle size into the multimodal distribution prescribed by the volume asymmetry of the Voronoi cells in the FK phase. Here we present a new regime in which the Laves C14 phase of bcp developed below the glass transition temperature of the micelle core, where the mass transport was inhibited by the immobile block chains forming the core. The bcp micelle comprising a glassy core and a soft corona resembles the fuzzy colloid and the strong van der Waals attraction between the cores directs their organization into C14 phase to minimize the interparticle interaction energy under the metastable condition.
