Effect of Nanotube Functionalization on the Properties of Single-Walled Carbon Nanotube/Polyurethane Composites

A commercially available aliphatic thermoplastic polyurethane formulated with a methylene bis(cyclohexyl) diisocyanate hard segment and a poly(tetramethylene oxide) soft segment and chain-extended with 1,4-butanediol was dissolved in dimethylformamide and mixed with dispersed single-walled carbon nanotubes. The properties of composites made with unfunctionalized nanotubes were compared with the...

The Effects of Functionalized Multi-walled Carbon Nanotube on Mechanical Properties of Multi-walled Carbon Nanotube/Epoxy Composites

The mechanical properties of the multi-walled carbon nanotube (MWCNT)/epoxy composites affected by carboxyl and amino functionalized MWCNT are investigated. Tensile tests of the specimens were carried out to obtain mechanical properties of MWCNT/epoxy composites for various weight-percents (wt %) of MWCNTs. In order to properly predict the mechanical properties of MWCNT reinforced epoxy composi...

Thermal Property of Multi-Walled-Carbon-Nanotube Reinforced Epoxy Composites

In this study, epoxy composite specimens reinforced with multi-walled carbon nanotube filler were fabricated using shear mixer and ultra-sonication processor. The mechanical and thermal properties of the fabricated specimens were measured and evaluated. From the electron microscope images and the results from the measurements of tensile strengths, the specimens having 0.6 wt% nanotube content s...

Multi-walled Carbon Nanotube Film Sensor for Ethanol Gas Detection

A kind of resistance-type multi-wall carbon nanotubes (MWNTs) film sensor was fabricated using layer-by-layer self-assembly, and an astable multivibrator circuit was designed for resistance measurement. The electrical properties of MWNTs film sensor were investigated, and also its ethanol gassensing properties with varying gas concentration are characterized at room temperature. The experiment ...
