Sneck, Auteur ; R. Knaapen, Auteur ; H. Heezen, Auteur ; A. Smith, Auteur Année de publication : 2013 Article en page(s) : p. 137-139 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Dépôt de couches minces atomiques Photopiles Index. décimale : 667.9 Revêtements et enduits Résumé : The EU-funded research project, R2R-CIGS, seeks to develop low-cost continuous production processes for flexible solar cells. Atomic layer deposition (ALD) is a coatings technology widely used in the micro-electronics industry as it can create very thin coatings of high quality. However, in its normal form, it is relatively slow as the coating precursors are applied sequentially. A system has been developed in which the different precursors can be applied sequentially to a moving web, achieving significantly higher production rates. The development of this coating system and the introduction of the first commercial coating machines of this type are described.

Surface modification of polymers for biomedical applications / P. Alves in SURFACE COATINGS INTERNATIONAL, Vol. 96, 3 (06/2013)  

[article]  inSURFACE COATINGS INTERNATIONAL > Vol. 96, 3 (06/2013) . - p. 140-147 Titre : Surface modification of polymers for biomedical applications Type de document : texte imprimé Auteurs : P. Alves, Auteur ; P. Ferreira, Auteur ; M. H. Gil, Auteur Année de publication : 2013 Article en page(s) : p. 140-147 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Biomatériaux Cellules -- Adhésivité Greffage (chimie) Implants médicaux Polymères en médecine Polymérisation sous plasma Rayonnement ultraviolet Technique des plasmas Traîtements de surface Index. décimale : 667.9 Revêtements et enduits Résumé : A large number of different materials are used in a wide range of biomedical applications for which biocompatibility is essential. In order to combine this with the desired bulk structural properties, it is frequently desirable to apply some form of coating or other surface modification. Factors involved in the interactions between the body and implants are discussed. The process of cell attachment to surfaces is complex and takes place in several stages. Depending on the application, this attachment may be essential or highly undesirable. Surface modification may be based on physical methods such as flame treatment, corona discharge, UV radiation exposure or laser ablation. Chemical methods include etching, surface oxidation, hydrolysis, chemical grafting and surface coating. Various aspects and applications of these technologies are considered. Surface modification is a very important aspect of the creation of medically viable polymeric and non-polymeric biomaterials and thus the use of coating techniques in the creation of biomaterials has been growing over recent decades as they can improve the application properties of materials in end uses ranging from catheters to endoprostheses and cardiac valves.

Getting to the roots of rheology : a bio-based thickener that enhances coating performance / C. Kemp-Griffin in SURFACE COATINGS INTERNATIONAL, Vol. 96, 3 (06/2013)

Kemp-Griffin, Auteur Année de publication : 2013 Article en page(s) : p. 160-161 Langues : Anglais (eng) Catégories : Agents coalescents Biomatériaux Cellulose La cellulose est un glucide constitué d'une chaîne linéaire de molécules de D-Glucose (entre 200 et 14 000) et principal constituant des végétaux et en particulier de la paroi de leurs cellules. Epaississants Extrait sec Nanofibres Polyacryliques Revêtements en phase aqueuse -- Additifs Rhéologie Index. décimale : 667.9 Revêtements et enduits Résumé : Curran is a novel type of cellulosic thickener for water-borne coatings, based on nanofibres which also significantly strengthen the applied coating. The reinforcing effect derives not only from the physical form of the product but also from its hydroxyl functionality. In addition, it has been found that in some formulations it is possible to reduce coalescent levels - and all this with a product derived from waste material.
