利用分形对无机粒子/高聚物体系分散效果的评定

Evaluation of Dispersion of Inorganic Particle/Polymer System by Fractal

利用分形的特点 ,通过自建模型 ,对原位气泡拉伸法制备的高聚物复合材料的分散效果进行定量分析。实验结果表明 ,分形维数为 0 6～ 1 3时 ,颗粒的分散比较均匀 ,在一定范围内 ,分形维数越小 。

Based on the fractal peculiarity, a self-made fractal mathematical model was used to quantitatively analyze the granules dispersion of the prepared polymer. The results showed when the fractal dimensionality was 0.6～1.3, the granules dispersion was homogeneous and within a certain range, the smaller the fractal dimensionality, the better the dispersion was.
