In the presentation, an overview of the methods which were developed for preparation of organic/inorganic hybrid materials, based on the conventional regenerated cellulose fibres with an attached layer of inorganic particles are given. Various inorganic particles were used (e.g. nano-sized silicon oxide, magnetite particles), either in situ formed on the fibres’ surface or deposited onto fibres from pre-prepared stable dispersions. Different mechanisms of formation of respective types of particles were investigated in relation to fine structure and surface morphology of fibres, which acted as nucleating/adsorbing sites. Study of composite fibres’ properties is presented, relating to their structure and morphology (wide and small angle x-ray scattering, IR spectroscopy, scanning electron microscopy) as well as their surface properties, especially from the point of view of surface potential and charge (zeta potential, charge titrations).
B.04 Guest lecture
COBISS.SI-ID: 15602198A review of different non-traditional fibres is given in the paper. Different isolation procedures are described. Mainly technical fibres are obtained, which means that cellulose fibres are multicellular structures with individual cells bound into fibre bundles. Different retting processes can be performed in both acid and alkaline mediums respectively, and by enzymatic treatment. The procedure used influences fibres surface morphology. Structure, chemical composition and properties of biofibres from agricultural by-products, e.g. wheat straw, pineapple leafs, sugarcane bagasse, hop stems, sponge, Musaceae plants, etc are introduced. In addition to fibres from different grass and legume species and from sea grass are presented in the presentation. Fibres from different non-conventional origins are compared and their potential utilization is discussed.
