“…Presently, latex organic–inorganic composites keep gaining academic and industrial interest due to a wide range of possible applications and a beneficial combination of polymer properties with inorganic materials functionality. − Inorganic nanoparticles can be incorporated into latexes during polymerization process, attached to the latex surface via electrostatic, hydrogen, or covalent bonding, or “in situ” deposited on the latex surface . Such latex-inorganic composites have been already used for fabrication of coatings with high refractive index, improved hardness, water and stain resistance, , self-sterilizing, and many others useful properties. To the best of our knowledge, latex coatings containing sorbents selective to radionuclides have not been previously reported, although hybrid polymer-inorganic thin films for selective adsorption and subsequent determination of radionuclides are known to the researchers .…”

Here we present a new approach to improve fixation of radionuclides on contaminated surfaces and eliminate their migration after nuclear accidents. The approach consists in fabrication of latex composite coatings, which combine properties of polymeric dust-suppressors preventing radionuclides migration with aerosols and selective inorganic sorbents blocking radionuclides leaching under contact with ground waters and atmospheric precipitates. Latex/cobalt hexacyanoferrate(II) (CoHCF) composites selective to cesium radionuclides were synthesized via "in situ" growth of CoHCF crystal on the surface of carboxylic or amino latexes using surface functional groups as ion-exchange centers for binding precursor ions Co(2+) and [Fe(CN)6](4-). Casting such composite dispersions with variable content of CoHCF on (137)Cs-contaminated sand has yielded protective coatings, which reduced cesium leaching to 0.4% compared to 70% leaching through original latex coatings. (137)Cs migration from the sand surface was efficiently minimized when the volume fraction of CoHCF in the composite film was as low as 0.46-1.7%.

“…It is believed that coating it with the shell can greatly improve the surface properties and stability of the core material, and affording comprehensive properties not possessed by any single component [5]. Due to their unique performance advantages, core-shell nanocomposites have become a research hotspot in the areas of coatings [6,7], adhesives [8,9], optics [10][11][12], electronics [13,14], biomedicines [15][16][17][18], and lubrication [19,20], and also present great potential in the future field of new materials.…”

In recent years, core–shell composite particles with organic polymer as the core and inorganic SiO2 as the shell have attracted widespread attention and prompted robust scientific endeavors. The encapsulation of SiO2 can endow the polymer core with a variety of important properties, and is of great significance for the synthesis of multi–functional materials, having favorable application prospects in coating, polishing, medical, optical, magnetic, lubrication and other fields. In this paper, the recent advances in the preparation of core–shell polymer@SiO2 composite particles are reviewed. From the perspective of interface bonding mechanisms between the core and the shell, this paper mainly focused on the following five aspects: Pickering stabilization, acid–base interaction, charge interaction, bridging of coupling agent, hydrogen bonding, and other actions. Additionally, applications of core–shell polymer@SiO2 particles are also discussed. It is expected that this article can provide scientific guidance for the preparation of polymer@SiO2 core–shell particles, further enriching their species and broadening their applications.

In this article, silica sol (diameter: 8–100 nm) and polymer latex (Tg < 25°C) were mixed and dried at room temperature to prepare nanocomposite films with high silica load (≥50 wt %). Effects of silica size, silica load, and the Tg of the polymer on the film‐forming behavior of the silica/polymer latex blend were investigated. The transparency, morphology, and mechanical properties of the nanocomposite films were examined by UV–Vis spectroscopy, SEM, and nanoindentation tests, respectively. Transparent and crack‐free films were produced with silica loads as high as 70 wt %. Thirty nanometers was found to be the critical silica size for the evolution of film‐forming behavior, surface morphology, and mechanical properties. Colloidal silica particles smaller than this critical size act as binders to form strong silica skeleton. This gives the final silica/polymer nanocomposite film its porous surface and high mechanical strength. However, silica particles with sizes of 30 nm or larger tend to work as nanofillers rather than binders, causing poor mechanical strength. We also determined the critical silica load appeared for the mechanical strength of silica/polymer film at high silica load. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
