Abstract:
The present invention relates to a process for producing nanostructured films obtained from block copolymers exhibiting a dispersity index of between 1.1 and 2, limits included, without nanostructuring defects, on a surface, in order for this treated surface to be able to be used as masks for applications in microelectronics.
Abstract:
A composite sheet is manufactured by depositing a multi-layer coating on the outer surface of a substrate, the coating comprising a metal layer and an outer polymeric layer formed from a precursor comprising a polymerizable composition that includes a olefin group and a moisture curable group, such as an isocyanate or silane group. After the precursor is applied, the composite sheet is exposed to beam radiation or plasma discharge, ozone, and moisture, which respectively promote polymerization and curing at different sites of the precursor. The function of the cured polymeric layer preferably includes protecting the metal layer from corrosion. The amenability of the isocyanate or silane functionality to moisture-promoted coupling promotes substantially full conversion and curing of the precursor, even of portions of the substrate that are geometrically shadowed from incident beam radiation.
Abstract:
The invention relates to a process for the preparation of a composite material, said composite material comprising a substrate and a layer on the substrate, comprising a vapor-depositing step in which a compound comprising a triazine compound is deposited on the substrate at a pressure below 1000 Pa, whereby the layer is formed, wherein during the vapor-depositing step the temperature of the substrate lies between −15 ° C. and +125 ° C. The invention further relates to a composite material, obtainable by the process as disclosed.
