Fractal Aggregation of Phase Separation in Polymer Blends

【摘要】：正 Great progress has been made on the investigation on the dynamics of phase separation in alloy and polymer systems. It has been found out that there exists a dynamic scaling behavior for the structure function in the process of phase separation. But we still could not understand what the physics picture is for the dynamic scaling of the structure function, which characteristic of the separation phase structure results in the dynamic scaling phenomena, etc. In this letter, the feature of the cluster aggregation is investigated and the rea-
