Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : A novel hyperbranched polyol has been derived from epoxidised soybean oil fatty acid methyl ester. Aqueous PUDs were prepared using the soy polyol as soft segment and compared with one containing a conventional polyester diol. Use of the soy polyol led to slightly softer films with notably superior water resistance and hydrophobicity. Note de contenu : - Practical and environmental benefits of vegetable oils
- Desirable aims in formulating PUDS
- Four PUDs prepared and compared

LactideLe lactide est le diester cyclique de l’acide lactique et le monomère qui permet de synthétiser le PLA (Poly Lactique Acide) par polymérisation d’ouverture de cycle (ROP).
Issu de l’acide lactique (ou acide 2-hydroxypropanoïque) et produit par fermentation du saccharose ou du glucose, le lactide est d’origine naturelle et renouvelable. Ce produit s’inscrit parfaitement dans le cadre du développement de la chimie verte. Le lactide, étant issu de l’acide lactique qui possède 2 formes stéréo-isomériques (acide lactique L(+) et acide lactique D(-)),existe sous 3 formes stéréo-isomériques : la forme L-lactide, la forme D-lactide et la forme Méso-lactide.

Ressources renouvelablesIndex. décimale : 667.9 Revêtements et enduits Résumé : Two biodegradable cyclic esters, ?-caprolactone and lactide monomer, were incorporated into co-polyols. Lactide monomer is obtained from renewable resources. Increasing lactide levels reduced the crystallinity and increased the Tg of the polyols. When these polyols were incorporated into PUD dispersions, the highest lactide content showed increased film stiffness, hardness and scratch resistance.

Textiles et tissus à usages techniquesIndex. décimale : 667.2 Colorants et pigments Résumé : Printing of conductive inks is an attractive means of manufacturing of electronic components on flexible substrates including textiles. The textiles thus produced are often referred to as “e-textiles.” When high electrical conductivity is required, inks are preferably made from metal nanoparticles such as silver. However, such inks are expensive and generally not known to withstand severe washing and wearing to which textiles are normally subjected during the end use. In the present study, which forms a part of a larger study by the authors, waterborne dispersions of conductive grades of carbon black were converted into finished inks followed by washing and creasing tests to ascertain the durability of these inks. We found that not only were the inks stable after letdown with different binders, but they possessed high electrical conductivity despite the fact that the final pigment loading in all of the formulated inks was significantly less than the pigment loading that is generally found in commercial conductive inks. In addition, the electrical conductivity after washing and creasing tests of the formulated inks was found to be significantly greater than that of the tested commercial conductive inks. This shows that using large surface area, highly conductive grades of carbon black pigments in relatively small amounts in inks for textile printing is beneficial in achieving some of the critically required characteristics, particularly those pertaining to durability of the ink film.
