在有机凝胶中形成的微结构网络的分形结构被确定，使用原位流变学方法，连同耦合超临界流体CO2萃取/扫描电子显微镜技术。流变学的方法使我们能够在线测量的分形生长的网络。与传统的光散射技术相比，该技术获得的结果显示数据的散射要小得多。与传统的分形聚集体，这种类型的分形图案的生长是由一个非晶体分支机制，这是通过自失配成核和生长发生。(C)2001年美国物理学会。
The fractal structure of nanofiber networks formed in organogels is identified, using an in situ rheological method, together with a coupled supercritical fluid CO2 extraction/scanning electron microscopy technique. The rheological method allows us to have in-line measurements of the fractal growth of the nanofiber networks. In comparison with conventional light scattering techniques, the results obtained from this technique show much less scatter in data. Unlike conventional fractal aggregates, the growth of this type of fractal pattern is governed by a noncrystallographic branching mechanism, which occurs via self-mismatch nucleation and growth.
