  • Development of composite cellulose fibres with magnetic properties [Elektronski vir]
    Hribernik, Silvo ; Sfiligoj-Smole, Majda ; Stana-Kleinschek, Karin
    We are reporting on the preparation of organic/inorganic hybrid materials, namely cellulose fibrous networks with attached magnetic iron oxide particles. Research work was divided into three parts; ... pretreatment of regenerated cellulose fibres with an aim to activate their surface and enlarge the pore system, in order to enhance the adhesion of particles and allow their growth inside of fibres. Second part is concerned with the magnetite particles' synthesis and their properties; synthesis procedures were compared from the viewpoint of their suitability to be combined with cellulose fibres. Third part deals with the coating of fibres with magnetic iron oxide particles with different procedures. Effect of different pre-treatment procedures on fibres' supramolecular structure, enlargement of their pore system, surface potential and mechanical properties was investigated. Coating of fibres was carried out with an in situ formation of particles in presence of fibres, as well as with adsorption of particles from a pre-prepared dispersion. Composite magnetite-decorated cellulose fibres exhibit magnetic behaviour, degree of which is dependent on employed fibres' pre-treatment in combination with specific synthesis protocol for magnetite formation. Developed magnetic fibres are being considered as a shielding material for electromagnetic radiation.
