Synthesis and experimental investigation on thermal conductivity of nanofluids containing functionalized Polyaniline nanofibers

The authors propose a fast and novel method for the synthesis of polyaniline nanofibers and their incorporation into DI-water as a nanofluid. The thermal conductivities of the nanofluids are measured from 10 °C to 80 °C by using the transient plane source (TPS) method. The particle loading amount of nanofibers affected the thermal conductivity of the nanofluids. Scanning Electron Microscopy (SEM) was used to characterize the physical properties of the nanofibers....

A New Class of Opacified Monolithic Aerogels of Ultralow High-Temperature Thermal Conductivities

The main objective of this research project was to create a material with a very low thermal conductivity at high temperatures, for the conservation of energy in high temperature systems. To accomplish this goal, the researchers incorporated carbon nanofibers into the mesoporous network of monolithic aerogels, with up to a 20 wt.% through an accelerated-gelation sol-gel process. The synthesis process also involved the use of supercritical drying of the aerogels to ...

Latex and two-roll mill processing of thermally-exfoliated graphite oxide/natural rubber nanocomposites

Thermally Exfoliated Graphite Oxide (TEGO) was mixed with natural rubber (NR) using a two-roll mill but the mixing of the TEGO with the NR didn't proceed as expected. Therefore the researchers had to modify the procedure and decided to pre-mix the TEGO and NR in an ultrasonically-assisted latex co-coagulation process followed by two-roll milling resulted in significant improvement in the thermal and electrical properties of the nanocomposite compared to the ...

In situ polymerized nanocomposites: Polystyrene/CNT and Poly(methyl methacrylate)/CNT composites

A series of polymer-matrix composites were synthesized by using a variety of carbon nanotubes (single-walled carbon nanotubes (SWCNTs), double-walled carbon nanotubes (DWCNTs) and multi-walled carbon nanotubes (MWCNTs)) and a polymer matrix (either polystyrene (PS) or poly(methyl methacrylate) (PMMA)). Different surfactants and polymerization methods were also used in order to generate a wide range of different composites. These different composites were all tested for thermal and electrical conductivity and characterized ...

Synergetic effect of thermal conductive properties of epoxy composites containing functionalized multi-walled carbon nanotubes and aluminum nitride

This study looked at the use of two different fillers to improve the thermal properties of an epoxy resin. The two fillers were multi-walled carbon nanotubes (MWCNTs) and aluminum nitride (AlN). Through the use of poly(glycidyl methacrylate) (PGMA) and a zirconate coupling agent the MWCNTs and AlN particles respectively were added to the epoxy resin. Through the use of 1 vol.% MWCNT and 25 vol.% AlN the researchers were able to ...
