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...
متن کاملThe 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...
متن کاملEffect 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...
متن کاملBiocompatibility of single-walled carbon nanotube composites for bone regeneration
OBJECTIVES The purpose of this study was to evaluate in vivo biocompatibility of novel single-walled carbon nanotubes (SWCNT)/poly(lactic-co-glycolic acid) (PLAGA) composites for applications in bone and tissue regeneration. METHODS A total of 60 Sprague-Dawley rats (125 g to 149 g) were implanted subcutaneously with SWCNT/PLAGA composites (10 mg SWCNT and 1gm PLAGA 12 mm diameter two-dimensi...
متن کاملElectronic structure control of single-walled carbon nanotube functionalization.
Diazonium reagents functionalize single-walled carbon nanotubes suspended in aqueous solution with high selectivity and enable manipulation according to electronic structure. For example, metallic species are shown to react to the near exclusion of semiconducting nanotubes under controlled conditions. Selectivity is dictated by the availability of electrons near the Fermi level to stabilize a c...
