Abstract (en)

[origin: WO2011086308A1] The invention relates to a multilayer structure that includes: a layer of a composition including a fluorinated polymer and a zinc oxide (ZnO), said ZnO being present in said composition in the form of particles having a weight proportion of less than 1%, said ZnO particles having a size between 10 and 100 nm and an adhesion promoter present in the body and/or surface of said layer; and at least one oxide layer (MOx) selected from among silicon oxide and aluminum oxide and having a thickness between 20 and 200 nm. Said structure has excellent properties of transparency within the visible range, excellent properties of opacity to UV rays, as well as good mechanical resistance and aging resistance while having excellent moisture barrier properties. Said structure can thus be advantageously used in the front surface of photovoltaic panels or for protecting organic light-emitting diodes.
