Immobilization of Metal-Organic Frameworks onto Cotton Fabrics

Abstract

Cotton materials are the renewable polymer and have many advantages to be used in scientifically and industrially. Since hydroxyl groups are present in many parts of cellulose, many applications and various studies have been developed by using these functional groups for chemical reactions. This thesis describes the synthesis, analysis and applications of cotton materials that are immobilized of metal-organic frameworks. In chapter 2, we suggested the synthetic methods for the immobilization of metal-organic frameworks onto cotton fabrics. Solvothermal methods and an alternative approach synthetic methods are described. The successful deposition of UiO-66 and ZIF-8 crystals was confirmed by analytical techniques including powder X-ray diffraction, ATR-IR and SEM. Most meaningfully, the two kinds of metal-organic frameworks were excellent surface coverage for cotton fabrics. And we suggested that step-optimization for chemical attachment and growth of UiO-66 onto cellulose. In chapter 3, synthesis of water-stable and hydrophobic cotton with immobilization of hydrophobic metal-organic framework onto cotton fabric is described via solvothermal method and post-synthetic modification. This approach is the first example for water-stable and hydrophobic cotton, and hydrophobicity of Cotton-MOFs is measured by water-contact angle and stability by water vapor test
