    Non-invasive techniques can be used to study membranes formed by a watery mixture from layering to 25 m.
    in many applications, the water-based dispersion of polymer particles is dried under defined environmental conditions and/or techniques to form a continuous thin layer with special properties and forms.
    the purpose of this practical study is to propose a newly developed non-invasive technique based on a visible light reflector, which is used to study membranes formed from a layered to 25 m

    sample holder is made of crystalline silicon (c-Si) because the interference streaks produced by the beam reflected at the air/liquid sample and liquid sample/c-Si are essential to determine the sample thickness.
    for polymer collizes with a minimum film temperature higher than room temperature, this setting is used to determine the evaporation rate and film-forming temperature.
    the output of the
    analysis experiment can improve the versatility of the experimental device by controlling the temperature of the sample holder and controlling the microclimate chamber (temperature and relative humidity).
    the composition, viscosity of the liquid and different types of polymer coll coll pellets, various water dispersions were studied and some results were discussed.
    new challenge is to analyze the output of the experiment by considering the distance between particles and the interference between particles.
    study was published
    in the Journal of Coating Technology and Research
    , p. 16, pp. 1571-1580.
