ELECTRORHEOLOGICAL MATERIALS BASED ON GRAPHENE/POLYMER NANOCOMPOSITES

On constitutive equations for electrorheological materials

Constitutive equations for electrorheological (ER) fluids have been based on experimental results for steady shearing flows and constant electric fields. The fluids have been modeled as being rigid until a yield stress is reached. Additional stress is then proportional to the shear rate. Recent experimental results indicate that ER materials have a regime of solid-like response when deformed fr...

Smart Polymer/Carbon Nanotube Nanocomposites and Their Electrorheological Response

This review article summarizes the preparation of polymer/carbon nanotube (CNT) nanocomposites and their applications as electrorheological (ER) fluids. These ER fluids exhibited a controllable electro-response under an applied electric field due to the presence of well-dispersed CNTs. The background, morphology, preparations, and characteristics of these materials are discussed, specifically f...

Highly Efficient White Light-emitting Diodes Based on Layered Quantum Dot-Phosphor Nanocomposites as Converting Materials

This paper reports on the enhanced photoluminescence (PL) of nanocomposites through the layered structuring of phosphor and quantum dot (QD). Green phosphor of Sr2SiO4:Eu, red QDs of CdSe/CdS/CdZnS/ZnS core-multishell, and thermo-curable resin were used for this study. Two kinds of composite (layered and mixed) were prepared, and the schemes for optical energy transfer between QD and phosphor w...

3D Packaging Materials based on Graphite Nanoplatelet and Aluminum Nitride Nanocomposites

Nanostructured composites with efficient percolation networks are promising candidates for packaging materials due to their high thermal conductivity. In this study, we investigate the thermal conductivity of composites consisting of a combination of exfoliated graphene nanoplatelet (xGNP) and aluminum nitride (AlN) particles in polyvinylidine fluoride (PVDF) matrix. The surfaces of the AlN par...
