Abstract
A composition according to an embodiment includes particles of metal-organic framework (MOF) including a central metal of zirconium, and two adjacent zirconiums on a surface of the particle has a structure represented by Formula 1. The composition may inhibit formation or growth of ice crystals through amino acid bond obtained by size control and surface modification of the metal-organic framework particles.
Claims6
A composition comprising:
- particles of metal-organic framework (MOF), each particle comprising central metals of zirconium and linkers which are organic ligands for connecting the central metals,
- wherein at least two adjacent zirconiums on a surface of the particle have a structure represented by Formula 1:
- wherein Zr is the zirconium on the surface of the particle;
- R1 and R2 are each alkyl having 1 to 5 carbon atoms;
- and
- R3 is one selected from the group consisting of Thr, Val, Ala, Ser and Gly,
- wherein an amino group (—NH2) of R3 is bound to the alkyl of R2.
