    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Gunilla Carlsson; Karlstads universitet.; Karlstads universitet.; Karlstads universitet.; Karlstads universitet.; [2004]
    Nyckelord :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;

    Sammanfattning : 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.. LÄS MER
