Claims30
A porous composite structure, comprising:
- a substrate comprising a plurality of nanostructures;
- a particle layer disposed on a surface of the substrate;
- a liquid;
- and
- an interlayer, wherein the interlayer is disposed on the surface of the substrate, and the particle layer is disposed on a surface of the interlayer,
- wherein the interlayer comprises a hydrolyzed, dehydrated and condensed product of a compound represented by Formula 1:
- H2N—R1—Si(OR2)3 Formula 1
- wherein, in Formula 1,
- R1 is a C1-C20 alkylene group or a C6-C20 arylene group, and
- R2 is hydrogen, a C1-C20 alkyl group, a C6-C20 aryl group, or Cl.
