Structural Characteristics of Fiber Networks

A uniform object has Df=d, while for more open stractures in which the density decreases with distance from the center, Df d. Taking into account the fact that the formation of fibrous networks is controlled by nucleation and growth (6c, 8, 12a, 17], the method to be introduced is based on the famous Avrami equation, [15a] which was developed to describe the nucleation and growth of bulk crystals [15a]. It has the form 

Real time monitoring of the rheological changes has been demonstrated to be a simple and accurate method to follow the kinetics of fiber network formation. The crystallinity can be obtained from the elasticity of the material. According to Einstein s relation, the volume fraction of suspended particles in a system can be correlated to its specific viscosity [16a], 

As has been discussed, the structure of a fiber network in a material is important since it affects the macroscopic properties of the material. Therefore, understanding the principles of fiber network formation in SMGs is necessary to the development of strategies to control the micro/nanometer structure in order to acquire materials with superior macroscopic properties.
