2. 1. Functional Textile Coatings Containing Flake-shaped Fillers : investigations on selected optical and electrical properties

   Author : Veronica Malm; Ilda Kazani; Högskolan i Borås; []
   Keywords : Flakes; fillers; textile coating; properties; multilayered mica; effect pigment; angle-dependent colour change; metals; conductivity; resistance measurements; e-textiles; flexibility; durability; Textil och mode generell ; Textiles and Fashion General ;

   Abstract : This thesis investigates the manufacturing and characterisation of functionalised textile coatings containing different types of flake-shaped fillers with angle-dependent colour-changing and electrically conductive properties, respectively. Common benefits of these types of flakes are their high aspect ratio, which offers low filler loading with high functional performance. READ MORE

4. 2. Transmission Electron Microscopy of Graphene and Hydrated Biomaterial Nanostructures : Novel Techniques and Analysis

   Author : Sultan Akhtar; Klaus Leifer; Hilborn Jöns; Stefano Rubino; Marco Cantoni; Uppsala universitet; []
   Keywords : Graphene flakes; magnetic beads DNA coils; hydrated biomaterials; transmission electron microscopy; focused ion beam scanning electron microscopy; bright-field dark-field imaging; high resolution imaging; electron diffraction and cryogenic temperatures; Materialvetenskap; Materials Science;

   Abstract : Transmission Electron Microscopy (TEM) on light element materials and soft matters is problematic due to electron irradiation damage and low contrast. In this doctoral thesis techniques were developed to address some of those issues and successfully characterize these materials at high resolution. READ MORE

5. 3. Elastoplasticity of Grey Cast Iron FE-Algorithms and Biaxial Experiments

   Author : Hans E. Hjelm; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biaxial experiments; multiaxial elastoplastic behaviour; graphite flakes; FE-codes; hardening behaviour; graphitic grey cast iron;

   Abstract : This thesis focuses on multiaxial elastoplastic behaviour of graphitic grey cast iron with the aim to provide physically appropriate and numerically reliable constitutive relations for use in FE-codes. To achieve this goal, this work is divided into three parts: Biaxial experiments are performed on thin cruciform specimens. READ MORE

7. 5. Inhibition of Aluminium Pigments for Waterborne Coatings

   Author : Philip Karlsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen evolution; AFM; surfactant; aluminium pigment; polymer; silica stabilisation; water based; adsorption; inhibition; waterborne; printing ink; QCM-D; AAS; reflectometry; encapsulation; paint; metallic pigment; coating; XPS;

   Abstract : Micrometer-sized aluminium flakes for use as pigments in waterborne coatings need protection, since the reaction between aluminium and water causes formation of aluminium hydroxide and hydrogen gas. The aluminium hydroxide destroys the metallic appearance of the pigment flakes and the evolution of hydrogen gas leads to a dangerous pressure build-up in the paint containers. READ MORE
