Claims35
A composite membrane comprising:
- an organic layer having a plurality of through holes;
- and
- ion conductive inorganic particles disposed in the through holes,
- wherein a hydrophobic coating layer is disposed on a surface of the ion conductive inorganic particles and the hydrophobic coating layer comprises at least one condensation reaction product,
- wherein an amount of the at least one condensation reaction product is in a range of about 0.1 part by weight to about 30 parts by weight, based on 100 parts by weight of the ion conductive inorganic particles, and
- wherein the ion conductive inorganic particles are single-body particles, and each single-body particle has a first surface exposed at a top surface of the composite membrane and a second surface exposed at a bottom surface of the composite membrane.
