Abstract:
A multi-layered film, a backsheet for photovoltaic modules, a method of manufacturing the same, and a photovoltaic module are provided. The multi-layered film can be configured so that a resin layer including a fluorine-based polymer and an oxazoline group-containing polymer is formed on a substrate. As a result, the resin layer including the fluorine-based polymer can have excellent durability and weather resistance, and show high interfacial adhesive strength to the substrate. During the preparation of the multi-layered films, a drying process can also be performed at a relatively low temperature, so that the manufacturing costs can be reduced and the quality of the product can be prevented from being deteriorated by thermal deformation or thermal shock. The multi-layered film may be effectively used as the backsheet in a variety of photovoltaic modules.

Abstract:
A coherent material is formed on a substrate ( 10 ) by providing a precursor suspension ( 14 ) in which particulates are suspended in a carrier fluid, and directing the precursor suspension ( 14 ) at the substrate ( 10 ) from a first source ( 12 ). Generally contemporaneously with application of the deposited precursor suspension ( 14 ) to the surface, hot gases, e.g. hot gases produced by a flame ( 16 ), are directed at the substrate ( 10 ) from a remote second source ( 18 ) to fuse the particulates into the coherent material.
Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zur Erzeugung sehr dünner, stark hydrophober und oleophober Schichten auf polymeren Substraten. Die erfindungsgemäßen Schichten sind in kochendem Wasser stabil und verhalten sich resistent gegen das Scheuern mit Kunststoffvliesen unter Druck. Nach dem beschriebenen Verfahren werden Substratoberflächen mit physikalischen Methoden vorbehandelt. Die anschließende Beschichtung mit einer Lösung von fluoralkylfunktionellen Organopolysiloxanen in Wasser oder Alkohol und Tempern der Substrate bei höherer Temperatur führt zu den gewünschten Eigenschaften.
