  1. 1. Latex Colloid Dynamics in Complex Dispersions Fluorescence Microscopy Applied to Coating Color Model Systems

    Author : Gunilla Carlsson; Karlstads universitet.; Karlstads universitet.; Karlstads universitet.; Karlstads universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi; Kemi; Chemistry; fluorescence microscopy; coating color; colloid; latex; diffusion; Brownian motion; film formation; polymer interaction;

    Abstract : Coating colors are applied to the base paper in order to maximize the performance of the end product. Coating colors are complex colloidal systems, mainly consisting of water, binders, and pigments. To understand the behavior of colloidal suspensions, an understanding of the interactions between its components is essential.. READ MORE

  2. 2. Flocculation with Polyelectrolytes in Latex and Microbial Systems

    University dissertation from Institute for Surface Chemistry, Box 5607, S-114 86 Stockholm, Sweden

    Author : Leif Eriksson; Lunds universitet.; Lund University.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; floc strength; shear sensitivity; fractal dimension; floc structure; patch flocculation; adhesion; bridging; flocculation; charge compensation; adsorption; ionic strength; molecular weight; charge density; Cationic polyelectrolytes; latex; bacteria; activ; Physical chemistry; Fysikalisk kemi;

    Abstract : Adsorption of cationic polyelectrolytes onto polystyrene latices was studied as function of polymer chemical composition and molecular weight, polymer and surface charge density and ionic strength. The ratio between polymer charges and surface charges was close to one when distances between polymer and surface charges were equal. READ MORE

  3. 3. Bimodal Hard/Soft Latex Blends

    University dissertation from Department of Polymer Science & Engineering, Lund University

    Author : Daniela Vidovska; Lunds universitet.; Lund University.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biopolymers; Polymerteknik; Polymer technology; Kemiteknik och kemisk teknologi; Chemical technology and engineering; aggregation; mechanical modeling; latex blends; viscoelastic properties;

    Abstract : Polymer dispersions are employed in a wide variety of applications as film formers. Especially in the coating-, paint-, pharmaceutical and hygiene industry polymer dispersions are to a large extent used as barriers, controlled-release agents and adhesives. READ MORE

  4. 4. Dispersion Coating for Active Food Packaging: : Aroma Interactions and Oxygen Scavenging

    University dissertation from Fakulteten för teknik- och naturvetenskap

    Author : Anna Nestorson; Karlstads universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik; Chemical Engineering; Kemiteknik; Active food packaging; Dispersion coating; Latex; Aroma compounds; Oxygen scavenging;

    Abstract : ABSTRACTActive packaging materials prolong the shelf life or preserve the quality of packed food by absorbing oxygen, ethylene, moisture or odours, or by releasing antimicrobial agents, antioxidants or flavours. In dispersion coating, a latex is applied onto paper or paperboard to form a barrier film against water, water vapour, oil or gases. READ MORE

  5. 5. Tailored adhesion of PISA-latexes for cellulose modification and new materials

    University dissertation from KTH Royal Institute of Technology

    Author : Joakim Engström; KTH.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PISA; latex; RAFT; Cellulose Nanofibrils; Cellulose Nanocrystals; Nanocomposites; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : This thesis is focused on applying modification chemistry to already known cellulosic substrates from wood (i.e. cellulose nanofibrils, CNFs, and cellulose nanocrystals, CNCs). READ MORE
