Sels de borateIndex. décimale : 667.2 Colorants et pigments Résumé : New photoinitiating systems composed of benzothiazolestyrylium dyes as chromophores and n-butyltriphenylborate anion as electron donor were prepared and characterised. Photoredox pairs consisting of hemicyanine dyes and organoborate salts may act as visible-light photoinitiators for the radical polymerisation of multifunctional acrylates. The efficiences of these photoinitiator systems are based on the free energy changes of an electron transfer from borate salt to the dye. Experimental results show that the photoinitiating ability of the photoredox pair tested strongly depends upon the reduction potential of hemicyanine dye, the oxidation potential of borate salt, and the structure of the dicationic dye.

Polymérisation en émulsionIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : A cationic polyacrylate emulsion (CPAE) with a core-shell structure was prepared by seed polymerization. The emulsion copolymerization was carried out with the core monomoers of butyl acrylate (BA) and methyl methacrylate (MMA), the shell monomers of BA, MMA, and a home-made cationic monomer with the initiator potassium persulfate. The structure of CPAE was characterized. No 'C=C' double bond was detected in the structure of CPAE by FT-IR and 1H-NMR spectra, indicating that the polymerization reaction was complete. DSC curves showed that there were two glass transition temperature in the structure of CPAE, indicating that the emulsion particle featured a core-shell structure. The core-shell structure of CPAE was also confirmed by TEM observation. Many improvements to the coating properties emerged when CPAE was used as a leather finishing agent. The result leathers has uniform and clean grain and comfortable handle. The coating had strong adhesion and its resistance to wet and dry rub fastness was up to grade 4.5.

Structure chimiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Superhydrophobic hybrid film coatings were prepared from the dispersions of siloxane-modified polyacrylate associated with organo-modified clay (OMC-20A) and hydrophobic-fumed silica (FS-H15) coated on glass and cement boards by a dipping process. The hydrophobicity, surface morphology, surface energy, and surface roughness of the obtained hybrid film coatings (HBFCs) were investigated. The results showed that the hydrophobicity of the obtained HBFCs was related to surface roughness and the roughness profile of the surface. HBFCs obtained using 10 phr OMC-20A with 35 phr FS-H15 in hybrid coatings and fabricated by four dipping provided high roughness surfaces (Rq) at 546.67 nm with a micro-nano-binary structure and a low surface energy at 2.35 mN/m leading to superhydrophobic surfaces on the coated glass and cement boards demonstrating 151.34° and 150.88° water contact angles, respectively. As a result, these HBFCs coated on cement board performed great water repellent and self-cleaning. Note de contenu : - Experimental : Materials

Traitement thermiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Thermally modified wood (TMW) is increasingly used in exterior applications as an alternative to tropical hardwoods or wood impregnated with biocides. Despite its enhanced biological durability and dimensional stability, a surface treatment of TMW with coating systems can be required in certain applications. This study assessed material characteristics of Norway spruce and Scots pine wood that was thermally modified according to the ThermoWood® process and their effect on the performance of commercially available coating systems: a solventborne oil, a waterborne alkyd-reinforced acrylate paint and a waterborne acrylate paint. Residual extractives and remaining degradation products found in TMW, carry the risk of causing discoloration or of interfering with the curing reactions of coating systems. The penetration of coating systems into TMW was not found to differ from unmodified wood, although an excessive penetration of solventborne oil was found occasionally for TMW. The adhesion strength of waterborne coatings depended on the system that was used. While one system performed sufficiently on TMW, the other coating systems showed a considerable reduction in adhesion strength already after a mild treatment (<200°C). This reduction could not be attributed to the increase in hydrophobicity of TMW that was evident from contact angle measurements, but was rather related to the mechanical interaction of the specific substrate/coating system.
