This one-atom thick crystal of carbon, gathers a set of unique physico-chemical properties, ranging from its extreme mechanical behavior to its exceptional electrical and thermal conductivities, which...

A nanocomposite of colloidal graphene oxide (CGO) and polyaniline (PANI) was fabricated via in situ oxidation polymerization in the presence of CGO prepared via a modified Hummers method without a dopant, in which the graphene oxide was individually exfoliated. Its electrorheological properties and other physical characteristics were studied.

A new sample environment is introduced for the study of soft matter samples in electric fields using small-angle neutron scattering instruments. The temperature controlled and features external electrodes, allowing standard quartz cuvettes to be used conducting or containing ions investigated without risk electrochemical reactions occurring at electrodes. For 12.5 mm cuvettes, maximum applied f...

We analyze the electrorheological effect in immiscible fluid mixtures with dielectric mismatch. By taking the electric field effect into account, which couples to the dynamics of domain morphology under flow, we propose a set of electrorheological constitutive equations valid under the condition where the relative magnitude of the flow field is stronger than that of the electric field. Through ...

Monodisperse polystyrene (PS) seed latex was initially prepared by a dispersion polymerization, and then polyaniline (PANI)-coated PS composite particles were synthesized by diffusion and polymerization of aniline at the interface. Characteristics of the obtained PS/PANI composite particles such as morphology and thermal property were examined using SEM and TGA, respectively. In addition, we em...
