Titre : CO2-laser treatment of indium tin oxide nanoparticle coatings on flexible polyethylene terephthalate substrates Type de document : texte imprimé Auteurs : Tobias Königer, Auteur ; Thomas Rechtenwald, Auteur ; Ihab Al-Naimi, Auteur ; Thomas Frick, Auteur ; Michael schmidtM, Auteur ; Helmut Münstedt, Auteur Année de publication : 2010 Article en page(s) : p. 261-269 Note générale : Bibliogr. Langues : Américain (ame) Tags : Revêtements 'Nanoparticule oxyde indium-étain' ITO 'Substrats Polyéthylène téréphtalate' 'Traitement laser CO2' 'Essai flexion oscillatoire' Index. décimale : 667.9 Revêtements et enduits Résumé : A CO2-laser treatment was used to improve the electrical conductivity of coatings of indium tin oxide (ITO) nanoparticles on flexible polyethyleneterephthalate (PET) substrates. The electrical conductivity and the transparency of CO2-laser-treated ITO nanoparticle coatings were characterized with regard to the application as transparent electrodes. Furthermore, the stability of the electrical conductivity under oscillatory bending was investigated. A specific resistance of 0.12 Ω cm is obtained by CO2-laser treatment without thermally damaging the PET film. The improvement of the electrical conductivity can be explained by a slight sinter neck formation. For a film thickness of 3 μm, a sheet resistance of 400 Ω/□ and a transmission in the visible range of 80 % were achieved. The stability of the electrical conductivity of CO2-laser-treated ITO nanoparticle coatings under bending was investigated using a specially constructed device for the application of various oscillatory bending loads. For a bending radius of 10 mm, the sheet resistance does not exceed 1000 Ω/□ after 300 bending cycles. Compared to commercial sputtered ITO coatings, CO2-laser-treated ITO nanoparticle coatings show a significant higher stability under oscillatory bending.

Titre : Effects of surface pretreatment and deposition conditions on the gas permeation properties and flexibility of Al2O3 films on polymer substrates by atomic layer deposition Type de document : texte imprimé Auteurs : Dung-Yue Su, Auteur ; Yueh-Hua Kuo, Auteur ; Ming-Hung Tseng, Auteur ; Feng-Yu Tsai, Auteur Année de publication : 2019 Article en page(s) : p. 1751-1756 Note générale : Bibliogr.

Pretreating polyimide (PI) and poly(ethylene terephthalate) (PET) substrates with an aqueous KOH solution greatly lowered the gas permeability of the ALD Al2O3 films as a result of improved affinity between the substrate surface and the ALD precursors. Varying the ALD conditions—including lengthening the precursor exposure, elevating the deposition temperature, and changing the precursor sequence—enhanced physisorption of ALD precursors on the polymer substrate, which improved nucleation of the ALD films to reduce defects in the films and lower their gas permeability. Activation energy for permeation determined from the temperature dependence of the permeability of the ALD films indicated that the ALD films deposited under the optimized condition contained smaller and few permeation-enhancing defects. The optimized ALD films possessed a low water vapor transmission rate of ~ 10−6 g/m2 day that met the stringent requirement of organic and flexible electronics, while also exhibiting excellent mechanical flexibility by withstanding repeated bending with small increases in gas permeability. Our results provide valuable insights into the development of flexible barrier thin films for the encapsulation of organic and flexible electronics.

Titre : Preparation of titanium dioxide compound pigments based on kaolin substrates Type de document : texte imprimé Auteurs : Yan Quanxiang, Auteur ; Yun Lei, Auteur ; Jizu Yuan, Auteur Année de publication : 2010 Article en page(s) : p. 229-237 Note générale : Bibliogr. Langues : Américain (ame) Tags : 'Dioxyde titane' 'Substrats kaolin' Colorants 'Valeur absorption huile' Blancheur Index. décimale : 667.9 Revêtements et enduits Résumé : Titanium dioxide compound pigments were prepared by hydrolysis of tetrabutyl titanate on the surface of kaolin substrates. The coating processes were investigated by various factors in single-factor tests, and the products were tested by oil absorption value and whiteness. The results show that the optimum compound pigments reach a whiteness of 94.0% and an oil absorption value of 35.5 mL/100 g. The products were further characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and zeta potential analyzer. The XRD analysis indicates that the microstructure of the coating on a kaolin substrate is mainly anatase. Transmission electron microscopy images clearly reveal that the layer of TiO2 consists of randomly oriented small particles with no agglomeration outside the kaolin surface.
