  1. 1. High Clay Content Cellulose Nanocomposites for Mechanical Performance and Fire Retardancy

    Författare :Lilian Medina; Lars Berglund; Jeffrey W. Gilman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanocellulose; nanofibril; nanofiber; CNF; nanoplatelet; nanostructure; tactoid; montmorillonite; MTM; foam; aerogel; porosity; PVA; poly vinyl alcohol ; epoxy; moisture; biocomposite; biomaterial; biobased; flame; cone calorimetry; gas barrier; coating; film.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Materials based on wood can offer sustainable alternatives to fossil-based plastics and composites, and show interesting mechanical properties. However, the issue of their flammability is generally unresolved. In this thesis, eco-friendly, fire retardant clay-cellulose nanofibril materials are investigated. LÄS MER

  3. 2. Gradation-Based Framework for Asphalt Mixtures

    Författare :Bernardita Francisca Lira Miranda; Björn Birgisson; Terhi Pellinen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asphalt; aggregate gradation; packing theory; asphalt microstructure; porosity; film thickness; rutting; moisture damage.; SRA - Transport; SRA - Transport;

    Sammanfattning : Asphalt mixture microstructure is formed by aggregates, bitumen binder and air voids. Aggregates make for up to 90% of the mixtures volume and the structure formed by them will depend mostly on their size distribution and shape. LÄS MER

    Sammanfattning : This Untethered Buffoon or the Trickster in Everything is a documented artistic research project (Doctoral Thesis) in Performative and Mediated Practices, comprising a series of excavations and vivisections of W(w)hiteness through clowning, making and thinging. This work/play traverses the fields of critical whiteness studies, performance and clowning, visual and cultural anthropology and decolonial critique. LÄS MER

  5. 4. Heterogeneous Film-Forming Latexes : Preparation - Morphology - Mechanical Properties

    Författare :Ola Karlsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; core-shell; particle morphology; heterogeneous latexes; particle size; crosslinking; hydrophilicity; poly isoprene-co-styrene-co-methacrylic acid ; monomer partitioning; internal particle viscosity; transmission electron microscopy TEM ; calorimetric reactor; two-stage; seeded emulsion polymerization; film morphology; mechanical properties; paper coating.; Polymer technology; biopolymers; Polymerteknik;

    Sammanfattning : This thesis describes the preparation of heterogeneous latexes, which may serve as binders in coating applications, and the characterization of these. The latexes were prepared in two-stage seeded emulsion polymerization. LÄS MER

  7. 5. Surface and porous structure of pigment coatings : Interactions with flexographic ink and effects on print quality

    Författare :Erik Bohlin; Caisa Johansson; Per Edström; Göran Ström; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coating; Pigment; Calendering; Porosity; Flexographic Printing; Print quality; Chemical Engineering; Kemiteknik;

    Sammanfattning : Each day, we are confronted with a large amount of more or less important information that we have to consider, and even in our digital society we need paper for communication, documentation and education. Much of the paper we use or are confronted by in our daily life, such as newspapers, books and packages, contains printed images or texts, and the appearance of both the print and the supporting surface is important.
