C
arbon Nanotubes (CNTs) have received great attentions with their extraordinarily fascinating behaviors such as structural,
mechanical, optical and electrical properties. They can be added into various polymers as fillers to prepare advanced
functional polymeric composites. However, due to their intrinsically poor dispersibility, achieving a uniform dispersion is
generally difficult. As one of the effective methods, milling processes are introduced to reduce the original size of the nanotubes
to improve dispersion, especially in the case of CNT suspension rheology for potential battery applications. With interesting
functionalities under external fields implying typical flow fields of laminar flow with most cases of rheological aspects and
electrical and magnetic fields, electro-responsive Electro-Rheological (ER) characteristics of polymer/CNT composite
systems from material rheological viewpoint are examined for various CNT composite particles with polystyrene and PMMA.
Interesting characteristics of their ER suspensions include yield stress, flow curve behavior and dielectric analysis. As for
Magneto-Responsive Magneto-Rheological (MR) materials, we coated the surface of soft-magnetic carbonyl iron particles
with CNT along with polymers to produce their favorable core-shell structure with apparently decreased particle density for
better dispersion and then characterized their MR characteristics under magnetic fields applied.
