Abstract

The invention discloses an in-situ visualization method of dispersity of an inorganic filler in plastic, belongs to the technical field of filler dispersity in plastic and relates to a method for special identification dyeing screening of an inorganic filler in plastic after film formation. Based on special identification of boronic acid-modified fluorescent molecules and surface hydroxyl of a layered filler, the inorganic filler in a press-molded plastic film is subjected to fluorescent labeling and through a fluorescence microscope or a confocal laser scanning microscope, the visualization result is measured and analyzed. The method is free of pre-modification or treatment on the inorganic filler, only utilizes immersion of any plastic film in boric acid fluorescent molecules, is an in-situ, non-destructive, rapid and effective visual identification method and can be widely used for effective screening of an inorganic filler in a composite material in the factory.

Description

technical field [0001] The invention belongs to the technical field of material dispersion evaluation, and in particular relates to a method for visually screening the dispersion of inorganic fillers in plastics through specific identification and dyeing after film formation. Background technique [0002] Two-dimensional inorganic layered materials (such as hydrotalcite LDHs, montmorillonite MMT, etc.) have been widely used as functional fillers in plastic products (such as polyethylene PE, polypropylene PP, etc.), with good preparation stability and strong functionality. organic-inorganic composite materials. In order to fully realize the functions of these nanofillers, their degree of dispersion in plastics is a very important indicator, which directly affects the mechanical properties, stability and functionality of composite materials. Therefore, the evaluation of the dispersion of inorganic fillers is of great significance in both theoretical research and industrial pr...
