Fractal dimension and phase transition of graphene oxide (GO) doped polyacrylamide
MetadataShow full item record
Graphene Oxide (GO)- Polyacrylamide composites prepared between 5 and 50 mu l GO were performed by Fluorescence Spectroscopy. The phase transition performed on the composites was measured by calculating the critical exponents, beta and gamma, respectively. In addition, fractal analysis of the composites was calculated by a fluorescence intensity of 427 nm. The geometrical distribution of GO in the composites was calculated based on the power law exponent values using scaling models. While the gelation proceeded GO plates first organized themselves into a 3D percolation cluster with the fractal dimension (D-f) of the composite, D-f = 2.63, then After it goes to diffusion limited clusters with D-f = 1.4, its dimension lines up to a Von Koch curve with a random interval of D-f = 1.14.
