Electrospinning of poly(vinylidene fluoride)/dimethylformamide solutions with carbon nanotubes

Abstract

For conductive carbon nanotube (CN)/polymer composite fibers to be obtained, CNs were incorporated into poly(vinylidene fluoride) (PVDF) in dimethylformamide (DMF) solutions and electrospun to form CN/PVDF fiber mats. The thinnest fiber was 70 nm thick. The percolation threshold for the insulator‐to‐conductor transition was 0.003 wt % CN for CN/PVDF/DMF solutions, 0.015 wt % CN for CN/PVDF spin‐coated films, and 0.04 wt % CN for CN/PVDF electrospun fiber mats. © 2003 Wiley Periodicals, Inc.

Carbon Nanotubes Reinforced Electrospun Polymer Nanofibres

“…As shown in Figure 5, the I~V curve indicates a non-ohmic behaviour, which changed with the filler concentration. Similar electrical behaviour was also reported for SWNT/PVDF [157] and MWNT/PEO [158] composite nanofibres. In an attempt to define the parameters that determine the conductivity of the nanofibre mats, McCullen et al [152] performed a study on electrospun MWNT/PEO nanofibre.…”

Shape memory effect and mechanical properties of carbon nanotube/shape memory polymer nanocomposites

“…Recently, because a large quantity composition technology was established, the cost of CNT decreased and then the applications to various fields became more and active. Many researches on mechanical, thermal and electric characterizations of CNT reinforced polymers are reported, such as CNT/polystyrene [6][7][8], CNT/PVA [9], CNT/PVDF [10], CNT/PP [11][12][13][14][15][16][17], CNT/nylon [18], and CNT/epoxy [19][20][21] etc.…”

Fundamental study of crystallization, orientation, and electrical conductivity of electrospun PET/carbon nanotube nanofibers

“…In fact, rapidly after their development, 4 CNTs have been widely used to improve electrical or mechanical properties of electrospun polymer nanofibers. [5][6][7][8] The presence of CNTs enhances the conductivity of the polymer solution and produces a larger electrical current during electrospinning. The addition of charge accumulation overcomes cohesive forces and intensifies repulsive forces among the charges accumulated inside nanofibers and fibers of smaller diameter are formed.…”
