Filler dispersion is one of the key factors that significantly affect the performance of composite materials. Quantitative description of the dispersion state of fillers in composites and the internal relationship between the dispersion state and the macro‐mechanical properties of composites are very important for the performance design, prediction and processing process control of composites. In order to quantitatively and visually describe the dispersion state of inorganic fillers in matrix, research the relationship between fillers dispersion and composites properties. Here, by the fluorescent labeling technology of inorganic fillers and the surface organic modification technology, a modified fluorescently labeled calcium carbonate (MF‐CaCO3) with red fluorescence effect and good dispersibility was obtained, and polypropylene (PP)/MF‐CaCO3 composites with different loadings were prepared (the weight concentrations of MF‐CaCO3 in filler is 2, 5, 10, 15, and 20 wt%, respectively). The fractal dimension D value for evaluating the uniformity of filler dispersion has been successfully received, based on fractal analysis and fluorescent labeling‐laser scanning confocal microscope three‐dimensional (3D) visualization technology. Through the statistical results of experimental data, it was found that the value of fractal dimension D was obviously negatively correlated with the macroscopic mechanical properties of composite materials. When the dispersion of the filler was the best, that is, the fractal dimension D value took on a minimum and the composites had the best impact resistance. At the same time, this method based on fractal analysis and 3D visualization technology provides a new idea for quantitatively describing the dispersion state of fillers and its relationship with the mechanical properties of composites.

“…Firstly, the spherical CaCO 3 was prepared by CMC as a template . Then the Eu(DBM‐Si) 3 has been successfully synthesized by our previously reported method, which can be graft‐modified with the hydroxyl groups on the surface of CaCO 3 endowing it fluorescent properties. The experimental process is as follows: 2 g of CaCO 3 was dispersed in a 40 mL solution (anhydrous ethanol: water 3:1, vol/vol) in a one‐necked flask and stirred for 30 min.…”

“…However, experiments based on this large scientific device are difficult to implement and expensive. In recent years, 3D visualization technology based on fluorescent labeling and laser scanning confocal microscopy (LSCM) has been widely used to analyze the dispersion state of fillers in various composites owing to its nondestructive, simple, and fast detection properties . Although the dispersion state of fillers in matrix can be obtained through this way, it is still a difficult problem to quantify the dispersion state of fillers in the field of composites.…”

The dispersion state of fillers in the polymer matrix is an important factor to determine the properties of the polymer composites. Here, a new method for the accurate quantitative evaluation dispersion state of fillers through three‐dimensional (3D) visualization and fractal analysis is reported. First of all, the data model of the dispersed state of the fillers is obtained through 3D visualization techniques. Then the fractal dimensions of different samples are obtained by software based on the fractal theory. As the filler increases, the fractal dimension is firstly decreases to a minimum and then increases. Under this extreme point condition, the theoretical dispersion state of the fillers is uniform. The accurate quantitative description of the dispersion state provides a new basis for establishing the relationship between the dispersion state and the mechanical properties of the fillers in various composites.

“…Numerous trials have been performed by many researchers and their coworkers to improve the inherent physicochemical properties of SR by incorporating filler materials, such as layered silicates (LS) [11][12][13], graphene [14,15], silica [16], boron nitride [17], carbon nanotubes [18], titania [19], zinc oxide [20], ceria [21], alumina [22], etc. However, the most promising results have been found with NCPs fabricated from LS due to its high available surface area, plate morphology, and exceptionally stable oxide network [23].…”

Naturally occurring nanomaterials are finding growing interests in tailoring properties of engineering polymers for advanced applications. The objective of this study was to develop environment-friendly nanocomposite films by reinforcing kaolinite nanofillers (1–10 wt%) in silicone rubber (SR) matrix using a simple solvent casting technique. Kaolinite-reinforced films showed substantial improvement in mechanical (tensile strength, Young’s modulus, and elongation at break) and thermal properties at very low filler loading (5 wt%). The improvement of solvent resistance nature of the fabricated films was another critical aspect of this study. Unfilled SR film showed ~19% weight loss when immersed in toluene for 4 h at 25 °C, whereas only ~4% weight loss was recorded in the case of 5% (w/w) kaolinite loaded film. Therefore, kaolinite has the potential to bring significant improvement in the properties of SR. This study indicates that there is plenty of room at the bottom for proper utilization of the potential of kaolinite for developing SR-based composite materials for potential applications in many industries, such as textile, household cleaning, construction, electronics, automotive, medical, etc.
