Abstract:
The invention herein relates to a surface protective dendritic polymer composition and to the cross-linked surface protective coating formed therefrom.
Abstract:
Disclosed is an encapsulation barrier stack, capable of encapsulating a moisture and/or oxygen sensitive article and comprising a multilayer film, wherein the multilayer film comprises: one or more barrier layer(s) having low moisture and/or oxygen permeability, and one or more sealing layer(s) arranged to be in contact with a surface of the at least one barrier layer, thereby covering defects present in the barrier layer, wherein the one or more sealing layer(s) comprise(s) a plurality of dendrimer encapsulated nanoparticles, the nanoparticles being reactive in that they are capable of interacting with moisture and/or oxygen to retard the permeation of moisture and/or oxygen through the defects present in the barrier layer.
Abstract:
The present invention relates to sol-gel composition for acrylic polymers-based substrate comprising at least a silane hydrolysate and at least an adhesion promoter comprising a dendritic polymer having hydroxyl and alkoxysilane groups at terminal ends thereof. The present invention also relates to an optical article coated with said sol-gel composition.
Abstract:
The present disclosure relates to an aqueous dispersible polymer composition comprising: (a) at least one of: (i) a dendritic polymer in admixture with a hydrophilic functionalizing agent; and (ii) a hydrophilic functionalized dendrimer; and (b) a non-dendritic polymer capable of forming bonds with said dendritic polymer to thereby form a dendrimer-non-dendrimer (DND) polymer hybrid that is dispersible in the aqueous phase, methods of forming the same and uses thereof.
Abstract:
A film-forming composition including a triazine ring-containing hyperbranched polymer with a repeating unit structure indicated by formula (1), and inorganic micro particles is provided. This enables the provision of a film-forming composition capable of hybridizing without reducing dispersion of the inorganic micro particles in a dispersion fluid, capable of depositing a coating film with a high refractive index, and suitable for electronic device film formation. (In the formula, R and R' are mutually independent and indicate a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and Ar indicates a divalent organic group including either an aromatic ring or a heterocyclic ring, or both.)
Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung partikulärer, nicht kovalenter Verbindungen bestehend aus einem amphiphilen dendritischen Makromolekül und Metallnanopartikeln, vorzugsweise Kupfernanopartikeln. Die erfindungsgemäß hergestellten partikulären Kompositionen zeichnen sich unter anderem durch eine hohe Dispersionsstabilität, hohe Verträglichkeit der Partikel zu polymeren Materialien und vor allem eine enorm hohe antibakterielle, fungizide und algizide Wirksamkeit aus, weshalb die Erfindung auch deren Verwendung als potentes antimikrobielles Mittel umfasst. Weitere funktionelle Eigenschaften lassen sich durch diese Verbindungen darrstellen wie zum Beispiel elektrische Leitfähigkeit, magnetische oder katalytische Eigenschaften und andere. Die Verbindungen werden unter anderem mit Vorteil zur anti-mikrobiellen Oberflächenbeschichtung oder zur Inkorporation in Materialien und Ausrüstungen, beispielsweise für den Medizinbereich, verwendet.
