  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. Bacteria - based self - healing mortar with bio - plastic healing agents : Comparative analysis on quantification and characterization of self-healing by various experimental techniques

    University essay from KTH/Betongbyggnad

    Author : Rahul Roy; [2020]
    Keywords : Mortar; crack; autonomous healing; bacteria; bioplastic; lactic acid derivatives PLA ; alkanoate derivatives AKD ; internal crack geometry; quantification; characterization; statistical analysis; Bruk; sprickbildning; självläkning; bakteriebaserademedel; bioplast; mjölksyrederivat PLA ; alkanoatderivat AKD ; inre sprickbildning; kvantifiering; karakterisering; statistisk analys;

    Abstract : Crack formation in concrete structures due to various load and non-load factors leading to degradation of service life is very common. Repair and maintenance operations are, therefore, necessary to prevent cracks propagating and reducing the service life of the structures. 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. Sizing of different pulp qualities

    University essay from Fakulteten för teknik- och naturvetenskap

    Author : Carolina Larsson; [2008]
    Keywords : Sizing; AKD; Rosin; edge wicking;

    Abstract : Edge wicking, i.e. in-plane wetting, is an important parameter for liquid packaging board products. Before filling of the products at the dairy the web is being sterilised with hydrogen peroxide (H2O2). READ MORE
