A novel jet dispersion technique was developed and investigated which enabled excellent carbon nanotube (CNT) dispersion by high exfoliation at even very low pressure drops. Suitable procedures were developed for the characterization of agglomerate size and fraction of individual CNTs. The appropriate characterization enabled the definition of a dimensionless dispersing parameter and the development of a kinetic model that describes CNT dispersion in dependence of the volumetric energy input. The rheological behavior of CNT suspensions in steady‐shear flows was investigated and demonstrated how the agglomerate fracture and CNT individualization influence the suspension viscosity.

多壁碳纳米管的射流分散性及其与悬浮流变学的关系

开发并研究了一种新颖的喷射分散技术，该技术通过在极低的压降下进行高剥离来实现出色的碳纳米管（CNT）分散。开发了合适​​的程序以表征团聚体尺寸和单个CNT的比例。适当的表征可以定义无量纲的分散参数，并开发出动力学模型，该模型描述了依赖于体积能量输入的CNT分散。研究了稳态剪切流中CNT悬浮液的流变行为，并证明了团聚体断裂和CNT的个体化如何影响悬浮液的粘度。
