UréeIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : In order to predict percolation temperature of AOT-Based microemulsions (AOT/iC8/H2O w/o microemulsions) in the presence of small organic molecules (ureas and thioureas), different Artificial Neural Network architectures (ANN) have been carried out using a Perceptron Multilayer Artificial Neural Network with three entrance variables (W = value of the microemulsion, additive concentration, logP value). Best ANN architecture consists in three input neurons, one middle layer (with two neurons) and one output neuron. Correlation values were R = 0.9251 for the training set and R = 0.9719 for the prediction set. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=15551

SurfactantsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The interfacial composition, thermodynamic properties and structure parameters of the W/O microemulsion systems containing alkyl-3-methyl imidazolium bromide (CnmimBr, n = 12, 14, 16)/1-pentanol/n-octane/aqueous NaCl (HCl or NaOH) have been studied by a dilution method. The molar solubility of 1-pentanol in oil phase (X0a) and the molar fraction of 1-pentanol at the interfacial layer (Xia) were obtained from the dilution equation of the W/O microemulsions. Furthermore, the distribution constant K of 1-pentanol between the interfacial layer and the bulk oil phase was determined, along with the standard Gibbs’ free energy change of transferring alcohol from the continuous oil phase to the interfacial layer, –ΔG00 -> i. Some structure parameters related to the microemulsion droplets were also calculated. The effects of NaCl, HCl and NaOH on the properties and structures of the W/O microemulsions were also explored. It was found that as the content of the aqueous NaCl (HCl and NaOH) increases, X0a and Xia would decrease, the formation of the microemulsion would be more thermodynamically spontaneous, and the radius of the water pool significantly increases.

SurfactantsIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Bicontinuous microemulsions are investigated as a model system for the specific adsorption phenomena of metal ions at the water-oil interface. Mixing an extremely hydrophobic ion extractant – tributyl phosphate (TBP) used here as co-surfactant – with an extremely hydrophilic sugar-based surfactant, we describe a new type of functionalized microemulsions that shows the classical Winsor phases, by varying the surfactant/extractant ratio. We focus on the Winsor III-type microemulsions by determining the phase diagrams whereas the microstructures were accessed by performing small angle neutron scattering experiments. Ultimately, these microemulsions may pave the way for the design of new selective ion extraction processes. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=9957

Tension superficielleIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Using a catalyst and cosolvent, hydroxyl-terminated polydimethylsiloxane (HPMS) based polyurethane (PU) micro-emulsion (WPU/HPMS) derived from isophorone isocyanate (IPDI) and poly- tetramethylene glycol (PTMG) was synthesised by self-emulsifying copolymerization. The polymer was then used in leather finishing.
The structure, rheological behavior, morphology and heat performance were characterized by Fourier transform infared spectroscopy (FT-IR), 1H nuclear magnetic resonance (1H NMR), gel permeation chromatography (GPC), light scattering (LS), transmission electron microscopy (TEM), interfacial tension (IT), wide-angle X-ray diffraction (WAXD), differential scanning calorimeter (DSC) and thermogravimetry (TG).
The results reveal that WPU/HPMS micro-emulsion is endowed with low surface tension, pseudoplasticity and thixotropy, which are beneficial to the properties of coating. DSC and TG diagrams also reveal that the application range of product was enlarged. Furthermore, the WPU/HPMS micro-emulsion was found to be a good finishing agent, endowing leather with a brightness, softness, plump/full and smooth surface, and thus improving the quality of leather.Note de contenu : - EXPERIMENTAL PROCEDURES : Materials - Synthesis of WPU/HPMS micro-emulsion
