- the fibers can be made either from bare NTC (crude or washed or treated), or from NTC mixed with a polymer powder or NTC coated / mixed with a polymer or other additives.
- the level of CNT in the composite material constituting the fibers is, according to the invention, less than 30%, less than 20% or even more preferably between 0.1 and
- the invention therefore proposes a process which makes it possible to increase the conductivity of thermoplastic composite materials containing CNTs, especially when the composition contains CNT levels of less than 10%.
- This effect is obtained surprisingly by modifying the heat treatment step of heating the composite material, this modification consisting of a gradual rise in temperature.
- the invention proposes a method which makes it possible not to deteriorate or even to improve the conductivity of thermoplastic composite fibers containing CNTs and possibly stretched, or even to make initially insulating fibers conductive.
- the spinning process comprises a first thermoplastic polymer extrusion step containing less than 30% of CNT, possibly followed by a stretching step.
- the invention consists in carrying out heat treatment during spinning and / or after spinning. Heat treatment consists of a gradual increase in temperature.
- Heat treatment consists of a gradual increase in temperature.
- the conductivity of thermoplastic composite fibers containing CNTs is improved. From the various examples, it is also shown that initially insulating composite fibers can be made conductive by this method.
- the resistivity of a thermoplastic composite fiber containing CNTs decreases during the rise in temperature and the level reached is maintained during the cooling step.
- the improvement of the conductivity by this method is almost instantaneous. Holding for one hour at the required heating temperature does not significantly improve the level of conductivity then attained.
- the examples described below show that a fixed temperature heat treatment is not very or not at all effective, while a heat treatment consisting of a gradual rise in the heating temperature systematically improves the conductivity of thermoplastic composite fibers. containing CNTs, in a range from 3% to 20% of CNTs. As can be seen, under certain conditions of heating temperature and charge rate in CNT, initially insulating fibers become even conductive.

- the fibers obtained have a resistivity that is less than 10 E 12 Ohm. cm, preferably less than 10 E 8 Ohm. cm, more preferably less than 10 E 4 Ohm. cm.

- the diameter of the fibers obtained is between
- melt spinning for example electro spinning, spin spinning, etc.
- polyamide fibers with different levels of CNT are polyamide fibers with different levels of CNT.
- the fibers comprising 3% and 7% of CNT are based on PA12 AMNO TLD, those whose CNT level is 10% and 20% are based on of PA6 Donamid® 27.
- the resistances are measured using a Keithley 2000 multimeter.
- Example 1 Process conditions for improving the conductivity of composite fibers based on thermoplastic polymer and CNT, or for rendering electrically insulating fibers of this type.
- fibers containing different levels of CNTs are considered. They are subjected to two different heat treatments in order to highlight the effects of the heat treatment according to the invention in improving the conductivity of the fibers. So the fibers are:
- two annealing temperatures are considered to be 120 ° C., a temperature higher than glassy transition temperature of the polyamide, and 250 0 C, temperature above the melting temperature of the polyamide.
- This table shows the comparison of the average resistivities p of PA-based composite fibers containing different levels of CNT, depending on the type of heat treatment received: either a 30-minute treatment at a fixed temperature or a treatment from room temperature. up to the annealing temperature at a rise rate of 5 ° C / min. In both cases, two annealing temperatures are considered, 120 ° C. and 250 ° C., and the average is obtained from three different samples. The resistivities are measured at room temperature with the exception of that at 120 ° C. in the case of treatment under a ramp at 5 ° C./min. pi: initial resistivity before heat treatment; -: the resistance is greater than the limit of detection.
- annealing at a fixed temperature does not make it possible to make the fibers which initially are not, that is to say containing up to 10% of NTC.
- the conductivity seems slightly improved by a fixed temperature annealing. But the annealing temperature does not seem to have any influence, the level of conductivity reached is not better at high temperature. It also remains an order of magnitude lower than that achieved through a gradual rise in temperature.
- a heat treatment with a gradual rise rate of the temperature of 5 ° C./min is effective for all the composite fibers considered in a range of 3% to 20% of CNT. For the lowest charge rates (3% and 7%) it is necessary to reach a temperature above the melting temperature of the polymer. This heat treatment makes it possible to make fibers containing 10% of CNT conductive, and this as soon as possible.
- Example 2 Typical Evolution of the Resistivity of a Composite Fiber Based on Thermoplastic Polymer and CNT During Heat Treatment
- the following example relates to the typical evolution of the resistivity of a PA6 Donamid® 27 and CNT-based composite fiber, which is initially conductive, during a heat treatment ranging from room temperature to 250.degree. speed of 5 ° C / min.
- a first cycle of heating is performed, then the fiber is cooled at a speed of about 2 ° C / min to a temperature below 50 ° C.
- a second heating cycle identical to the first is then performed.
- Figure 1 shows the typical evolution of the relative resistivity of a fiber as a function of temperature during such heat treatment.
- Relative resistivity (p / pO) is the ratio between the resistivity p of the fiber at the temperature considered and its resistivity pO at ambient temperature.
- Example 3 Effect of the annealing time on the resistivity of a composite fiber based on thermoplastic polymer and CNT.
- the influence of the time parameter on the resistivity has been observed by the depositor insofar as the latter has realized that it is the gradual increase of the temperature which makes it possible to improve the conductivity whereas until there, the heat treatment was carried out at a fixed temperature.
- NTC is placed in a thermal chamber where it is heated from room temperature up to 120 0 C at a speed of 5 ° C / min, then maintained at this temperature for one hour.
- FIG. 2 The evolution of the resistivity recorded over time is presented in FIG. 2. This is the evolution of the resistivity of a PA6 fiber containing 20% of CNT during a heating cycle ranging from room temperature up to 120 0 C at a rate of 5 ° C / min, followed by a plateau at this temperature for one hour.
- Example 4 Use of composite fibers based on thermoplastic polymer and thermally treated NTC as deformation sensor.
- This example shows the evolution of the resistivity of composite fibers annealed in-situ as a function of stretching.
- the heat-treated fiber is glued on a paper test-tube.
- the multimeter is connected to the fiber by two copper wires also glued on the test piece, and the contact is provided by silver lacquer.
- the fibers are stretched at a rate of 1% deformation per minute and the resistance is recorded at the same time as the tensile test. We can therefore deduce the evolution of the resistivity as a function of 1 ⁇ elongation, taking care to correct the diameter of the fiber by elongation.
- FIGS. 3 and 4 show the evolution of the stress and the resistivity of fibers comprising respectively 3% and 10% of CNT, heat-treated at 250 ° C at a rate of 5 ° C / min, depending on the elongation. These two quantities are "corrected", that is to say that the variation of the section with elongation has been taken into account.
- the resistivity of the fiber after a slight decrease, increases with elongation until the fiber breaks.
- the variation of the electrical properties under mechanical stress therefore allows applications as deformation or stress sensors.
- metal fibers are difficult to weave, they are heavy and can be degraded by corrosion. They are not very suitable for the production of technical textiles or lightweight and high performance garments, unlike the composite fibers according to the invention.
- carbon fibers these have a high electrical conductivity and a high tensile strength in the axis of the fiber. However, they lack flexibility and can be woven only by specific methods unlike composite fibers according to the invention. In addition the carbon fibers are not suitable for applications in which they would be subject to strong deformations (stretching, folding, knotting).
- the composite conductive fibers according to the invention constitute a fifth category which bypasses the weaknesses of the fibers previously described, the table below illustrating the properties in the various cases.
