In a hydrothermal synthesis process, a non-crystalline aluminum silicate similar to the clay mineral allophane was created. This synthetic mineral was subsequently incorporated as a nanofiller into both clear and multicolored aqueous emulsion paints. Analysis through X-ray diffraction confirmed the nanofiller’s amorphous structure, displaying a narrow particle size distribution with an average diameter of 1.2 µm and possessing a specific surface area of 228 m2/g. When integrated into clear films, this nanofiller notably enhanced wettability in comparison to films lacking the filler. Outdoor exposure tests further demonstrated that multicolored films containing the nanofiller exhibited superior antifouling properties when compared to films using a commercially available silica filler.
