  1. 1. Nanocellulose surface functionalization for in-situ growth of zeolitic imidazolate framework 67 and 8

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Beyar Abdulla; [2020]
    Keywords : Zeolitic Imidazolate Framework; ZIF-8; ZIF-67; CNF@MOF; CNF@ZIF; TEMPO CNF; Nanomaterials; Nanocomposites; Metal-Organic Framework; Biopolymers;

    Abstract : This master’s thesis was conducted at the Department of Nanotechnology and Functional Materials at Ångström Laboratory as part of an on-going project to develop hybrid nanocomposites from Cladophora cellulose and a sub-type of metal-organic frameworks; zeolitic imidazolate frameworks (ZIFs). By utilizing a state-of-the-art interfacial synthesis approach, in-situ growth of ZIF particles on the cellulose could be achieved. READ MORE
