TriazolesLes triazoles sont des composés organiques cycliques comportant un cycle à 5 atomes, comportant deux double liaisons et 3 atomes d'azote et donc de formule brute C2H3N3. Elles sont aromatiques et font partie des cycles excédentaires en électrons.
Selon la position des atomes d'azote, on distingue les 1,2,3-triazoles (appelées V-triazoles) et les 1,2,4-triazoles (appelées S-triazoles).

The tests were carried out through the incorporation of the three compounds in different paint formulations, which were applied to polyvinyl chloride (PVC) and steel substrates. The coated panels were tested in Alexandria's western harbor's water.

SouduresIndex. décimale : 667.9 Revêtements et enduits Résumé : Fouling control coatings (FCCs) and irregularities (e.g., welding seams) on ship hull surfaces have significant effects on the overall drag performance of ships. In this work, skin frictions of four newly applied FCCs were compared using a pilot-scale rotary setup. Particular attention was given to the effects of coating water absorption on skin friction. Furthermore, to investigate the effects of welding seam height and density (number of welding seams per five meters of ship side) on drag resistance, a new flexible rotor was designed and used for experimentation. It was found, under the conditions selected, that a so-called fouling release (FR) coating caused approximately 5.6% less skin friction (torque) over time than traditional biocide-based antifouling (AF) coatings at a tangential speed of 12 knots. Furthermore, results of immersion experiments and supporting “standard” water absorption experiments showed that water absorption of the FR coating did not result in any significant impacts on skin friction. On the other hand, water absorption was found to actually lower the skin friction of AF coatings. This may be attributed to a smoothening of the coating surface. The effects of welding seam height and density on drag resistance were found to be substantial when welding seam height is above 5 mm, especially at high tangential speeds (above 15 knots). Using an interpolation approach, the pilot-scale welding seam drag data could be used to estimate the drag resistance at approximated full-scale conditions, equivalent to about one welding seam per five meters of ship side. It was shown, in this case, that the contribution of welding seams to ship skin friction could very well be less significant than those of FCCs when the welding seam height is below 5 mm, a representative value for full-scale welding seam height.

Revêtements antisalissures:Peinture antisalissuresIndex. décimale : 667.9 Revêtements et enduits Résumé : In a double benefit for the global economy and world climate, Evonik plans to make ship hulls invisible to micro-organisms and so to protect them against biofilms, algae, and bivalves. Growths of this kind, referred to as biofouling, push up fuel consumption in shipping and, thus also CO2 emissions on the world's oceans.
The International Maritime Organization estimates that the annual costs caused by biofouling lie in the billion-dollar range. Evonik is working on a solution to the problem in the form of 3 new eco-friendly coating that counteracts biofouling. The coating tricks micro-organisms into perceiving plain water in front of them, rather than the ship's hull ; as a result they often make no attempt to settle on the hull.
Biofouling has long been a problem for shipping companies the world over : organisms settle on the ship's walls, changing the smooth surfaces into a rough and ragged shell. This increases frictional resistance in the water, so that biofouling slows down ships. These thon need more energy to maintain their speed, which is bad news for bath fuel costs and the environment. Marine transport accounts far about 90% of global freight forwarding.Note de contenu : - One of the last unsolved problems in the industry

PolydiméthylsiloxaneLe polydiméthylsiloxane —[O-Si(CH3)2]n—, ou poly(diméthylsiloxane) selon la nomenclature systématique, communément appelé PDMS ou diméthicone, est un polymère organominéral de la famille des siloxanes souvent présent dans les shampoings. On l'y ajoute pour augmenter le volume des cheveux mais il peut également aller boucher les pores du cuir chevelu et rendre les cheveux gras. C'est une des raisons pour lesquelles se laver les cheveux tous les jours est très déconseillé avec un shampooing contenant des silicones.
Il existe également de l'amodiméthicone, qui est un dérivé du diméthicone.
Le polydiméthylsiloxane est un additif alimentaire (E900), utilisé comme antimoussant dans les boissons (Coca-Cola BlāK).
La chaîne de poly(diméthylsiloxane) forme également la structure de base des huiles et des caoutchoucs silicones.

Revêtements antisalissuresIndex. décimale : 667.9 Revêtements et enduits Résumé : It is well established that crosslinked polydimethylsiloxane (PDMS) based coatings have efficacious foul release characteristics. However, a trade-off between mechanical integrity of filled and crosslinked PDMS based coatings and their foul release performance has been a bottleneck for producing efficient and durable coatings. In the present study, we report a dual approach of nano-reinforcement of a bimodal PDMS network as a strategy to produce simultaneously reinforced and toughened PDMS networks with facile release of macrofoulants from their surfaces. The nanocomposites of both unimodal and bimodal PDMS networks were prepared using oligomeric dihydroxyl functional PDMS precursor chains differing in their molecular weights by a factor of five and commercial Cloisite-20A nanoclay as the nanofiller. The clay layers were found to be mildly intercalated in the PDMS matrix, as revealed from investigations by scattering and imaging techniques at different length scales. While the unimodal PDMS networks did show nanoclay induced simultaneous reinforcement and toughening, at equivalent clay loadings, the bimodal PDMS nanocomposites seemed to stretch further with characteristic strain hardening before fracture. Dynamic mechanical analysis (DMA) and swelling studies of the nancomposites further confirmed the nanoclay induced reinforcement effect of the bimodal PDMS host matrix. The intrinsic low surface energy characteristics of PDMS were retained by bimodal blending of long and short chains and its subsequent nano-reinforcement. Macrofouling studies by panel immersion and release force measurements revealed that the macrofoulants could be dislodged from the nanocomposite coatings with a shear force < 0.05 MPa.
