These dyes showed a molar extinction coefficient in the range of 20 000–30 000 l/mol/cm. These compounds were characterised by strong solid-state fluorescence under long ultraviolet light (365 nm). Absorption and fluorescence spectra revealed that electron coupling originating from broad π-electron delocalisation and the keto–enol form is responsible for the large Stokes shift. These dyes were readily soluble in common solvents such as dichloromethane, chloroform, dimethyl formamide, tetrahydrofuran and dimethyl sulphoxide and were characterised by means of elemental analysis, proton nuclear magnetic resonance and mass spectrometry. Thermogravimetric analysis of solid-state fluorescent dyes show thermal stability up to 270 °C and can therefore be used for polymer application. The coloristic properties of these dyes were evaluated on polyester by the disperse dyeing method.

In the first step, polyurethane prepolymer was prepared by the reaction of hexamethylene diisocyanate and polypropylene glycol in the presence of a catalytic amount of dibutyltin dilaurate. In the second step, poly(urethane-imide) prepolymer was prepared by the reaction of synthesized polyurethane prepolymer in the first step with pyromellitic dianhydride in dimethylformamide. In the third step, the prepared poly(urethane-imide) (PUI) reacted with 2,2-bis (hydroxymethyl) propionic acid, and the reaction completed in the last step which involved neutralization and dispersion in water, where acidic poly(urethane-imide) was neutralized by the addition of triethylamine. The prepared poly(urethane-imide) dispersions were characterized by fourier transform infrared spectrometry, proton nuclear magnetic resonance spectroscopy (1HNMR), thermogravimetric analysis, and dynamic laser scattering. A series of PUI dispersions with 30 wt% solid content, viscosities of 9 ± 1 cps, and particle sizes of 78–133 nm range were prepared and characterized.

Traîtements de surfaceIndex. décimale : 668.4 Plastiques, vinyles Résumé : The performance of thermoplastic polyurethane (TPU) reinforced with natural fibers can be tailored through a suitable choice of the fibers nature or the type of surface treatment applied to them. The present work deals with the improvement of the interfacial properties of natural fibers, namely wood flour (WF) by the introduction of graphene oxide (GO), which may easily disperse on the WF surface to provide hybrid fibers (WF-GO). The latter were then used as reinforcement of a TPU matrix at different ratios of 1, 3 and 5 wt%. The different samples were characterized by FTIR and RAMAN spectroscopies, XRD, SEM and TGA to confirm the structure, morphology and the thermal stability of the prepared hybrid fibers as well as their composites (TPU/WF-GO). SEM micrographs revealed that the surface treatment applied to WF, the distribution of GO sheets on the fiber interface, and the dispersion of (WF-GO) on the polymer matrix were successfully carried out. The thermal stability of the TPU-base composites increased with the increase of WF-GO content from 325 °C for the pure TPU matrix to 343 °C for the composite reinforced by 5% of (WF-GO). In addition, the results confirmed that the incorporation of GO into WF led to a significant improvement in the mechanical properties of the TPU-based composites, with an improvement in strength from 10.9 MPa to 19 MPa.

VernisIndex. décimale : 667.9 Revêtements et enduits Résumé : In this study, we have targeted to improve the cleanability of coating as well as the systemization of coating from 2K to 1K. Thermosetting acrylic resin was prepared by using carboxyl acid and hydroxyl group containing monomers, modified with siloxane acrylate which is later cross-linked with highly methylated monomeric melamine cross-linker by catalysing the same with acid catalyst. Grafting of polymers was con firmed by FTIR analysis. The differential scanning calorimetry revealed the glass transition temperature. The synthesized copolymer was applied on metal substrate and the coating characterization viz. surface energy and contact angle is tested by Goniometer. The easy to clean effect was studied by permanent marker. Static water contact angle and contact angle hysteresis measurements proved the formation of hydrophobic surfaces. Samples displayed static water contact angle 99.8°. Increasing the melamine formaldehyde and acid catalyst percentage by keeping the hydroxyl value and siloxane content same showed better easy to clean property by increasing only siloxane content.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Reactive dyes based on di-(p-sulphophenoxy)-s-triazines were synthesised, characterised and applied to wool fabric by ink-jet printing. The extent of dye-fibre covalent bonding (% fixation) was measured on prints produced using different development methods. The most promising method to obtain high dye-fibre fixation values was to interleave the printed wool with a pre-wetted cotton fabric and store for 3 h. Steam fixation was also investigated but gave lower fixation values. The degree of dye hydrolysis vs time in the ink formulation was evaluated because ink stability is critical in commercial operation ; a reformulated ink based on a phosphate buffer was found to improve ink stability.
