Hydroxydes doubles lamellairesTags : 'Layered double hydroxide' Films 'Corrosion inhibitors' 'Aluminium alloy' Anticorrosion Index. décimale : 667.9 Revêtements et enduits Résumé : ZnAl layered double hydroxide (LDH) host films have been synthesized on aluminum alloy 2024 substrate via a facile crystallization method, and then intercalated with different corrosion inhibitor anions (vanadate, molybdate, and 2-mercaptobenzothiazolate). The structures, compositions, and morphologies of the as-synthesized films before and after the anion-exchange reaction were characterized by means of glancing-angle X-ray diffraction, Fourier transform infrared, X-ray photoelectron spectroscopy, and scanning electron microscope techniques. The anticorrosion performance of films was evaluated by potentiodynamic polarization and salt spray test. The results show that all inhibitor anions are successfully intercalated in the layered galleries, providing enhanced corrosion protection for the substrate alloy. The anticorrosion abilities of films loaded with inhibitor anions are ordered as LDH–VO3 > LDH–MBT > LDH–MoO4 > LDH–NO3.

In order to study fundamental properties of such polymers, a model system of four polyurethane macromonomers that differ in the average number of double bonds per molecule was developed. Free radical copolymerization of the polyurethane macromonomers with acrylates was carried out in aqueous phase using the polyurethanes as the reactive emulsifier. The stability of the product dispersions depends on the average number of double bonds per macromolecule and the weight ratio of hydrophilic polyurethane to the acrylic part. The content of the polyurethane double bonds and their conversion was measured by nuclear magnetic resonance (NMR) spectroscopy and by a titrimetrical method.

One barrier to adoption may be the mismatch between industries that are familiar with such processes but have no need, and industries that have need but are not familiar. Moreover, there are application-specific technical challenges to developing multilayer-coating processes. In this article, we describe our resolution of two specific issues in simultaneous multilayer coating of all-aqueous highly loaded slurries for new and emerging energy applications. The first issue is particle jamming (associated with shear-thickening) of the highly loaded slurries in the die internals, which we alleviated by adding small amounts of viscosity modifiers without reducing the solid loading. The second issue is a Marangoni-driven surface instability that resembles top layer de-wetting, which we solved by carefully selecting surfactants to tune the dynamic surface tensions of each slurry. Both issues were resolved early in a step-wise development, saving significant development cost which in our case was driven by expensive materials.

SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).
Sol-gel, ProcédéTags : Revêtements hybrides organiques / inorganiques - séchage UV revêtements mécanisme de guérison double Sol-gel Index. décimale : 667.9 Revêtements et enduits Résumé : A coating precursor containing both acrylate functionality and trimethoxysilane functionality was produced by reacting bisphenol-A glycerolate diacrylate with 3-isocyanatopropyltimethoxysilane. With this precursor, two different crosslinked networks can be produced. A polyacrylate network can be produced using a radiation-cure mechanism while a polysiloxane network can be produced by hydrolysis and condensation reactions involving the trimethoxysilane groups. The objective of the study was to determine the utility of this dual-cure system for generating rapid-cure coatings for corrosion protection. Coating properties were determined as a function of cure conditions. The results of the study showed that the formation of siloxane crosslinks was significantly hindered by the crosslinked network induced by the UV-curing process. Even though the overall conversion of trimethoxysilane groups to siloxane crosslinks was relatively low, coating barrier properties were significantly enhanced and coating free volume reduced. At ambient conditions, additional crosslinking occurring through siloxane bond formation increased within the first 4 days after UV-curing. Beyond this period, siloxane bond formation remained unchanged as did coating properties. Note de contenu : - Materials
