Dave, Auteur ; Sneha Saha, Auteur ; Sanjay Das, Auteur ; Nirmalya Moitra, Auteur Année de publication : 2015 Article en page(s) : p. 53-90 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Antimicrobiens Engins explosifs -- Détection Isolation acoustique Matériaux intelligents Matériaux piézoélectriques Matériaux poreux Peinture solaire Revêtements:Peinture Surfaces fonctionnelles Transition de phase En physique, une transition de phase est une transformation du système étudié provoquée par la variation d'un paramètre extérieur particulier (température, champ magnétique...). Cette transition a lieu lorsque le paramètre atteint une valeur seuil (plancher ou plafond selon le sens de variation). La transformation est un changement des propriétés du système. Index. décimale : 667.9 Revêtements et enduits Résumé : Disturbance of domestic ambience by external chemical and biological intruder have a direct impact on general hygiene, safety and sustainability. Although a significant progress has been made in modern science to tackle these problems, their application in coatings has rarely been carried out, which have a huge potential for development of customized coatings, that is on demand coating functionality. Inspired by these technologies, here, in this review we will describe some of the advances in modern science which have application in coatings for improvement of general health, hygiene, safety and sustainability. Introduction of functionalities in the coatings is the key for developing coatings with desirable properties, for example omniphobic surfaces, nanoparticle and polymers having antimicrobial properties when incorporated in coatings can easily improve the overall hygiene there by health. In similar fashion Piezo electric materials, and TNT color sensors when applied to coatings can detect damage sites in buildings and presence of explosives, thus, increasing the general safety. Furthermore, phase changing materials and coatings that can convert sunlight to electricity offers alternatives for maximizing output from natural resources providing a much sustainable environment.

Langues : Anglais (eng) Catégories : Air intérieur Antimicrobiens Dépolluants Isolation acoustique Matériaux -- Propriétés fonctionnelles Matériaux piézoélectriques Revêtements décoratifs:Peinture décorative Index. décimale : 667.9 Revêtements et enduits Résumé : The 21st century has seen an evolution of surface coatings for fulfilling a more focused functional role, other than the conventional one of decoration and protection. These functional coatings are able to have properties which are innovative and impactful and can significantly contribute to improving living life environmental comfort level. Disturbance of domestic ambience by external chemical and biological intruder have a direct impact on general hygiene and safety. Although a significant progress has been made in modem science to tackle these problems, which is functional coatings. Here, some of the functional coatings will be discussed and their impact on human health, comfort, safety and hygiene. Introduction of functionalities is the key for developing coatings with desirable properties, for example nano particle and polymers having antimicrobial properties when incorporated in coatings can easily improve the overall hygiene there by health. In similar fashion Piezo electric materials, when applied to coatings can detect damage sites in buildings, thus, increasing the general safety. Furthermore, phase changing materials and coatings that can convert sunlight to electricity offers alternatives for maximizing output from natural resources providing a much sustainable environment.
