Textiles et tissusIndex. décimale : 667.3 Teinture et impression des tissus Résumé : A novel method for fabric rope dyeing in supercritical carbon dioxide fluid has been successfully developed for the first time for commercial purposes by employing a custom-built machine. The influence of parameters such as system pressure, temperature, and dyeing time on fabric colour strength was investigated, and the parameters optimised. Moreover, the level dyeing property, reproducibility, and colour fastness were investigated and evaluated under various conditions. The carbon dioxide recycling efficiency and the running costs of the proposed process in comparison with conventional processes for commercial production purposes were also investigated. The rope dyeing results show significant influence of the process parameters on fabric colour strength. Satisfactory and commercially acceptable products with a good level dyeing property, high reproducibility of coloration, and good fastness, rated at 4–5 or 5 for washing and rubbing, were obtained with supercritical carbon dioxide fluid. Moreover, a carbon dioxide recycling efficiency ranging from 92 to 95.2% was possible. In comparison with conventional dyeing processes, running costs were lowered by employing the proposed process and rope dyeing machine.

GraphèneLe graphène est un cristal bidimensionnel (monoplan) de carbone dont l'empilement constitue le graphite. Il a été isolé en 2004 par Andre Geim, du département de physique de l'université de Manchester, qui a reçu pour cette découverte le prix Nobel de physique en 2010 avec Konstantin Novoselov. Il peut être produit de deux manières : par extraction mécanique du graphite (graphène exfolié) dont la technique a été mise au point en 2004, ou par chauffage d'un cristal de carbure de silicium, qui permet la libération des atomes de silicium (graphène epitaxié). Record en conduction thermique jusqu'à 5300 W.m-1.K-1. C'est aussi un matériaux conducteur.

Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : In this work, by exploiting the lubricity and barrier effect of graphene and the hydrophobic polymer (polyvinylidene fluoride, PVDF), a superhydrophobic graphene/PVDF composite coating (G/PVDF) with contact angle of approximately 153.3° was prepared on microarc oxidized aluminum alloy to protect the substrate from friction and corrosion. The G/PVDF coating was strongly bonded with the microarc oxidization (MAO) layer on the aluminum alloy by the ionic interactions between graphene and the cations of polyelectrolyte, and hydrophobic interactions between graphene and PVDF. Results show that the friction coefficient of the G/PVDF coating was lower than that of the MAO-only ceramic coating, with the lowest friction coefficient for the G/PVDF3 film of about 0.3, which demonstrates better antiwear property compared with the MAO-only ceramic coating. In addition, the superhydrophobic coating exhibited enhanced anticorrosion properties compared with the MAO-only ceramic layer, which is attributed to the combined effect of graphene and the superhydrophobicity of the surface.

Revêtements:PeintureIndex. décimale : 667.9 Revêtements et enduits Résumé : Hybrid isocyanurate was prepared by solvent-free trimerization of hexamethylene diisocyanate (HDI) and bis(isocyanatomethyl) cyclohexane (ADI), and characterized by gel permeation chromatography (GPC), gas chromatography (GC), nuclear magnetic resonance (NMR), and electrospray ionization mass spectrometry (ESI–MS). The results showed that ADI/HDI hybrid isocyanurate could be prepared with 2-hydroxypropyl-trimethyl-azanium catalyst at reaction temperatures between 50°C and 70°C. Both the GC and 1H NMR analyses identified a favorable linear relationship between the feed ratio of the starting monomers and the amount of each individual isocyanate incorporated into the oligomer (reaction ratio). Compared to coatings prepared from the mixture of ADI isocyanurate and HDI isocyanurate, the coatings from ADI/HDI hybrid isocyanurate possess higher distinctness of image.
