  1. 1. Chemical modification of regenerated-cellulose films with determined patterns and different regeneration mediums to achieve superhydrophobic properties

    University essay from Mittuniversitetet/Institutionen för kemiteknik

    Author : Pornpan Kongthong; [2021]
    Keywords : Surface roughness; regeneration of cellulose; Regenerated-cellulose; superhydrophobic surfaces; Alkyl Ketene Dimer AKD ; Scanning Electron Microscope SEM and X-Ray diffraction XRD ;

    Abstract : In our modern society there is a need to find a material that is biodegradable to reduce the use of plastic for a greener society. By means of superhydrophobic surfaces there is a possibility to replace plastic with cellulose and use Alkyl Ketene Dimer (AKD) as a sizing agent to make the surface hydrophobic. READ MORE

  3. 2. Biocomposite with Continuous Spun Cellulose Fibers

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Rocio Nahir Pineda; [2020]
    Keywords : cellulose fibers; biocomposite; vacuum infusion process; film-stacking process; polylactic acid;

    Abstract : The subject of this project is to study spun cellulose fibers made by Spinnova Oy inFinland. The fibers are spun using an environmentally friendly spinning process withoutuse of harsh chemicals. READ MORE

  4. 3. Influence of level of cellulose oxidation and surface treatment on the adhesion between cellulose beads

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Rasmus Källgren; [2020]
    Keywords : Cellulose; Fibre; Surface Coating; Layer-by-Layer; Oxidation; Cellulosa; Fiber; Ytbehandling; Layer-by-Layer; Oxidation;

    Abstract : With the growing impact of climate change on both political decisions and how companies develop their products, it is increasingly important to find environmentally friendly alternatives to fossil-based materials. One of the more interesting materials in this respect is cellulose, which is the world's most naturally occurring polymer and can be used in a variety of applications. READ MORE

  5. 4. Dissolution and fibre spinning of cellulose from an ionic liquid

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Erika Andersson; [2018]
    Keywords : Cellulose; scattering; ionic liquid; dissolution; regenerated cellulose fibre; structure-property relationship; materials chemistry; materialkemi; Chemistry; Technology and Engineering;

    Abstract : Regenerated cellulose fibres can become a sustainable alternative to cotton and polyester in textile applications. One method of producing such is dissolution of cellulose in an ionic liquid (IL) and regeneration through air-gap spinning. READ MORE

  6. 5. The Effect of In Vitro Gastrointestinal Condition on Aggregation of Nano Silica Particles

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Shuai Bai; [2018]
    Keywords : Silica nanoparticles; in vitro digestion; Aggregation; Asymmetrical flow field flow fractionation; DLVO; membrane interaction; food technology; livsmedelsteknologi; Chemistry;

    Abstract : The presence of Nano particles in food is a topic that have gain much attention lately. The aim of this study is to investigate the aggregation behavior of nano silica under in vitro gastrointestinal conditions using asymmetric flow field flow fractionation (AF4) coupled with several detectors.
