Method of forming a material having a predefined morphology

A method of forming a material, said method comprising:

• combining a self-assembling block copolymer with a crosslinkable polymer to form a mixture, 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 said self-assembling block copolymer, said crosslinkable polymer being selectively miscible with said second block species and having a volume fraction F3 in said mixture, said first and said second block species respectively having a volume fraction of F1A and F2A in said mixture;
• processing said mixture to form a material;
• prior to said combining:
• providing a tangible data collection comprising data in which each morphology of a plurality of morphologies and a range of (F2A+F3) of a plurality of ranges of (F2A+F3) are associated with each other, wherein (F2A+F3) denotes a sum of F2A and F3, wherein said data has a characteristic that a performance of said combining and said processing using a value of (F2A+F3) in any range of (F2A+F3) of the plurality of ranges of (F2A+F3) in the data collection forms a material having the morphology associated with said any range of (F2A+F3) in the data collection, and wherein the plurality of morphologies in the data collection comprises a morphology of spherical nanopores whose associated range of (F2A+F3) is from about 0.82 to about 0.94, a morphology of cylindrical nanopores whose associated range of (F2A+F3) is from about 0.70 to about 0.80, and a morphology of nanolamellae whose associated range of (F2A+F3) is from 0.60 to about 0.65;
• selecting from the tangible data collection the range of (F2A+F3) associated with a predefined morphology selected from the group consisting of the morphology of spherical nanopores, the morphology of cylindrical nanopores, and the morphology of nanolamellae;
• and
• preselecting (F2A+F3) from the selected range of (F2A+F3);
• wherein said processing comprises:
• applying the mixture onto a substrate forming a mixture coated substrate comprising a layer of the mixture on the substrate;
• and
• processing the mixture coated substrate to form said material in direct mechanical contact with the substrate, wherein the material is derived from the layer of the mixture and comprises a structural layer and an interfacial layer, wherein the structural layer comprises nanostructures having the predefined morphology and being surrounded by the crosslinkable polymer, wherein the interfacial layer lacks nanostructures and comprises the crosslinkable polymer, wherein the interfacial layer has a first thickness less than a second thickness of the structural layer, wherein the first thickness and the second thickness are each measured in a direction normal to an interface between the interfacial layer and the substrate, wherein a ratio of the first thickness to the second thickness is in a range from about 0.007 to about 0.6, wherein the first thickness is in a range from about 2 nm to about 30 nm, wherein the second thickness is in a range from about 50 nm to about 300 nm.
