Method for preparing an oriented-porosity dielectric material on a substrate by means of electromagnetic and photonic treatment

摘要

Provided a method for producing an oriented-porosity dielectric material on a substrate. The method includes depositing a composite layer on a substrate by vapor deposition comprising a material forming a matrix and a compound comprising chemical groups capable of being oriented under the effect of an electromagnetic field and/or photonic radiation; treating the composite layer to obtain the cross-linking of the material forming a matrix; and subjecting the substrate coated with the composite layer to an electromagnetic field and a photonic radiation.
