Structure including a material having a predefined morphology

摘要

A structure. The structure includes a substrate and a material adhered to said substrate. The material includes a structural layer and an interfacial layer. The structural layer includes at least one crosslinkable polymer and nanostructures having a predefined morphology. The nanostructures are surrounded by the at least one crosslinkable polymer in the structural layer. The interfacial layer essentially lacks nanostructures and includes essentially the at least one crosslinkable polymer.

1. A structure, comprising:
a substrate; and a material adhered to said substrate, wherein said material comprises a structural layer and an interfacial layer, wherein the structural layer comprises at least one crosslinkable polymer and nanostructures having a predefined morphology, wherein the nanostructures in the structural layer are surrounded by the at least one crosslinkable polymer in the structural layer, wherein the interfacial layer is disposed between the substrate and the structural layer and is in direct mechanical contact with both the substrate and the structural layer, wherein the interfacial layer lacks nanostructures, and wherein the interfacial layer comprises the at least one crosslinkable polymer, wherein the material is formed by combining a self-assembling di-block copolymer with the at least one crosslinkable polymer to form the mixture and heating the mixture to form the material, said self-assembling block copolymer including a first block species and a second block species respectively characterized by a volume fraction of F1 and F2 with respect to at least one self-assembling block copolymer, said at least one crosslinkable polymer being miscible with the second block species and having a volume fraction F3 in the mixture, said first and said second block species respectively having a volume fraction of F1A and F2A in the mixture; wherein (F2A+F3) is selected prior to said combining and in response to the predefined morphology having been previously selected; wherein (F2A+F3) denotes a sum of F2A and F3; wherein the predefined morphology is a morphology of spherical nanopores or a morphology of nanolamellae; wherein the predefined morphology is a morphology of spherical nanopores if a range of (F2A+F3) is from about 0.82 to about 0.94; and wherein the predefined morphology is a morphology of nanolamellae if the range of (F2A+F3) is from about 0.60 to 0.65.
