A study of pigment dispersion involves an understanding of the formation and properties of the solid/liquid interface. In the early stages of the process the solid/air interface is replaced by one between the solid and liquid. The pigment powder consists of aggregates/agglomerates of small particles and mechanical work is performed in dispersing particles into a liquid. The forces that exist at the interface determine the ease with which the process can be brought about, once dispersed the particles are free to move in their new environment and flocculation is prevented by various chemical and physical processes, all of which relate to the character of the solid/liquid interface. It is not surprising therefore that studies of these interfaces form an integral part of our understanding of the dispersion process, and of those aspects of pigment performance that are dependent on the state of dispersion.

Nanotechnology : Emerging trends / Pramod Raman Natuvetty in PAINTINDIA, Vol. LVI, N° 6 (06/2006)

[article]  inPAINTINDIA > Vol. LVI, N° 6 (06/2006) . - p. 89-98 Titre : Nanotechnology : Emerging trends Type de document : texte imprimé Auteurs : Pramod Raman Natuvetty, Auteur Année de publication : 2006 Article en page(s) : p. 89-98 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Nanotechnology is being heralded as the fastest developing technology that will redesign the future of several technologies, products and markets. Nanotechnology has become one of the important sectors, which is drawing immense interest, and it will replace most of the existing technology in use today. It is widely publicised to be an important technology that is going to change every aspect of our lives and lead to generation of new capabilities, new products and new markets. Because of its potential to change fundamentally whole fields of technology, it will not only influence technological development in the near future, but will also have decisive economic, ecological and social implications. Nations are focusing on this emerging technology in particular and serious research as well as industry efforts are being made. Terminology, segments, potential application & risk to the environment is discussed here. Note de contenu : Introduction Terminology and fundamentals Different approaches in nanotechnology - The top-down approach - The bottom-up approach - Segmentation of nanotechnology - Nano-materials - Why are nanoparticles important? - Coatings within coatings Major application The future of nanocoatings Risk of nanotechnology-negative consequences for health and the environment Conclusion Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11565 [article]
