Influence of CNT concentrations to polyurethane / multi-walled carbon nanotube composites on the thermoelectric performance

Wu Q., Hu J., The Hong Kong Polytechnic University, HK

In this paper, we investigated the possibility of applying polyurethane in thermoelectric application, and the influence of MWNT concentrations to polyurethane / multi-walled carbon nanotube composites on the thermoelectric performance. Polyurethane was used as the [...]

Water-dispersible graphene stabilized by PVA grafted graphene and its poly (vinyl alcohol) nanocomposites

Shang S.M., Gan L., Yuen M.C.W., The Hong Kong Polytechnic University, HK

In this study, we synthesized poly (vinyl alcohol) (PVA) functionalized graphene oxide (f-G) by esterification reaction and used this f-G to stabilize the dispersion of graphene in water. Finally, we used the f-G stabilized graphene [...]

Shang S.M., The Hong Kong Polytechnic University, HK

The delivery of unique nanospheres has aroused wide attention due to the potential applications in optical, electrical, magnetic, and biological devices. Special attention has recently been paid to the methods for controlling the size and [...]

Amphiphilic Polymeric Core-Shell Particles: Novel Synthetic Strategy and Potential Applications of the Particles

Li P., The Hong Kong Polytechnic University, CN

We have developed a novel and commericial viable route to a wide range of highly uniform, amphiphilic core-shell particles in nano- to micro-scaled sizes. Novel feature of this synthetic approach is that it combines graft [...]

Mechanical and Thermal Stability of Carbon Nanotube Junctions

Shi S.Q., Liu W.C., Meng F.Y., The Hong Kong Polytechnic University, CN

Mechanical and thermal stability of carbon nanotube junctions was studied using molecular dynamics simulation method. Junctions made from armchair and zigzag thin carbon nanotubes were first formed by thermal welding process, then tested under 1D [...]
