Abstract
In some embodiments, a metal-organic framework material includes tricarboxylate metal-organic frameworks. The tricarboxylate metal-organic frameworks include unmodified tricarboxylate ligands and modified tricarboxylate ligands. The modified tricarboxylate ligands are unmodified tricarboxylate ligand modified with aliphatic carbon chains. Methods of forming metal-organic framework materials and textiles containing modified metal-organic framework materials are also provided.
Claims4
A method of forming a modified textile, the method comprising:
- carboxymethylation of a surface of a textile;
- layer-by-layer growth of a copper tricarboxylate metal-organic framework film on the surface of the carboxymethylated surface;
- selecting an anhydride that will confer hydrophobicity to the copper tricarboxylate metal-organic framework film, wherein the anhydride is valeric anhydride;
- and
- forming a modified tricarboxylate metal-organic framework film by exposing the copper tricarboxylate metal-organic framework film to a determined effective amount of the valeric anhydride to produce a hydrophobic textile having a determined characteristic, wherein the determined characteristic is one of water contact angle, water stability, and degradation rate of the tricarboxylate metal-organic framework.
