Titre : Review of eco friendly green polyurethanes with non-isocyanates : current and future trends in green coatings Type de document : texte imprimé Auteurs : R. Kanchana, Auteur Année de publication : 2017 Article en page(s) : p. 55-71 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Acides aminés Les acides aminés (ou aminoacides) sont une classe de composés chimiques possédant deux groupes fonctionnels : à la fois un groupe carboxyle –COOH et un groupe amine –NH2. Parmi ceux-ci, les acides α-aminés se définissent par le fait que leur groupe amine est lié à l'atome de carbone adjacent au groupe acide carboxylique (le carbone α), ce qui leur confère la structure générique H2N–CHR–COOH, où R représente la chaîne latérale, qui identifie l'acide α-aminé.
Les acides α-aminés jouent un rôle fondamental en biochimie comme constituants élémentaires des protéines : ils polymérisent en formant des liaisons peptidiques qui aboutissent à de longues chaînes macromoléculaires appelées peptides.

Revêtements sans isocyanatesIndex. décimale : 667.9 Revêtements et enduits Résumé : Non-isocyanate polyurethane (NIPU) is a novel kind of polyurethane prepared by reaction of cyclo-carbonates and amines without use of toxic isocyanates.NIPU has attracted increasing attention because of its improvements in porosity, water absorption, thermal and chemical resistance over conventional polyurethanes. Conventional polyurethanes involve the use of isocyanates, which require hazardous and toxic phosgene for their manufacture. These monomers cannot be man ufactured without elaborate safety devices and h uge investment. Isocyanates are also considerably toxic and sensitive to moisture. Growing global awareness, Need to protect our environment and continually strive to ensure the safety, health and well-being of those in the industry and consumers has created a demand for environment-friendly products. Their potential technological applications include chemical-resistant coating, sealants, foam, etc. This review orbits around the syntheses of different kinds of NIPU, the reaction mechanism, and application of different kinds of NIPU in coatings.

PolyuréthanesIndex. décimale : 668.9 Polymères Résumé : Polyurethanes have been widely used in many fields due to their remarkable features such as excellent mechanical strength, good abrasion resistance, toughness, low temperature flexibility, etc. In recent years, room-temperature self-healing polyurethanes have been attracting broad and growing interest because under mild conditions, room-temperature self-healing polyurethanes can repair damages, thereby extending their lifetimes and reducing maintenance costs. In this paper, the recent advances of room-temperature self-healing polyurethanes based on dynamic covalent bonds, noncovalent bonds and combined dual or triple dynamic bonds are reviewed, focusing on their synthesis methods and self-healing mechanisms, and their mechanical properties, healing efficiency and healing time are also described in detial. In addition, the latest applications of room-temperature self-healing polyurethanes in the fields of leather coatings, photoluminescence materials, flexible electronics and biomaterials are summarized. Finally, the current challenges and future development directions of the room-temprature self-healing polyurethanes are highlighted. Overall, this review is expected to provide a valuable reference for the prosperous development of room-temperature self-healing polyurethanes.

TransuréthanisationIndex. décimale : 668.9 Polymères Résumé : Polyurethane(PU) is most commonly used polymer in various of applications due to its excellent properties. Conventional polyurethane are mostly synthesized by the reaction of isocyanates, polyols and chain extenders. Isocyanates used in this process increases a various health issue. To overcome come all these drawback of PU alternative method of polyurethane synthesis is developed. ln this review sustainable routes for the synthesis of non-isocyante polyurethane (NIPU) reported currently few method of NIPU synthesis reported such as polyaddition, polycondensation, rearrangement and ring opening polymerization are presented in this article. Attention has been given by researchers towards the synthesis of non-isocyanate polyurethane (NIPU), polyhydroxylurethane (PHU) by using most popular and industrially important by the reatiron of cyclic carbonate with diamine.
