For organic-inorganic composite materials, the spatial dispersion of inorganic fillers in the organic matrix is of great significance for designing and manufacturing high-performance composite materials. To improve the understanding of the micro-physical mechanism of the filler-reinforced polymer matrix, we studied the relationship between filler network structure and macro-mechanical properties of silicone rubber by using fluorescent labeling technology and three-dimensional (3D) visualization imaging.

How Amira-Avizo Software is used

The establishment of the 3D dispersion model of filler in silicone rubber is based on LSCM and Avizo Fire. […] The 3D visualization reconstructed process is done using Avizo. Through the Threshold Chosen and Volume Rendering to close to the real condition of filler contents in silicon rubber. Finally, the 3D images intuitively demonstrate the silica FZ dispersion in silicon rubber, and more information can be calculated by using Label Analysis and Volume Fraction. […] On the basis of 3D image of fillers, we constructed and simulated filler network structure along the backbone of silica aggregates with the use of Avizo Fire Skeletonization command
