Definitions
- the subject of the invention is a process for treating a polymer part with multicharged and multi-energy ions belonging to the list consisting of helium (He), nitrogen (N), oxygen ( O), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe).
- multicharged and multi-energy ions belonging to the list consisting of helium (He), nitrogen (N), oxygen ( O), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe).
- the invention has applications for example in the electronic field, where one seeks for example to suppress the deposition of electrostatic charges that can cause the destruction of electronic components placed on a polymer substrate, or in the automotive field, especially to limit the deposit of dust on a car dashboard.
- the dissipation of electrostatic charges it is obtained with dissipative materials and conductors which prevent electrical discharges and dissipate the charges resulting from the movements at high speed.
- the conductivity can be obtained by different ways:
- non-permanent additives such as fatty amine esters or quaternary amines. These substances, incorporated into a polymer matrix, migrate to the surface and react with the humidity of the air. In forming a wet film on the surface, they reduce the surface resistivity to about 10 14 ⁇ / ⁇ .
- Adhesion is an important phenomenon in the case of polymers which results in the sticking of pieces of paper, dust. This adhesion results from the contribution of the Van Der Walls forces produced by the polarity of the molecules located on the surface of the polymer and by the electrostatic forces induced by the very high surface resistivity.
- polymer parts In addition to bonding problems, polymer parts often have to operate in more or less aggressive chemical environments, with ambient humidity, with ambient oxygen, at very low or very high temperatures, and so on. which can lead to oxidation an increase in their electrical insulative character.
- Some polymers are loaded with chemical agents that protect against UV rays and oxidation.
- the rejection of these chemical agents to the outside has the effect of accelerating the surface oxidation which in turn reinforces the insulating nature of the polymer.
- the aim of the invention is to reduce the aforementioned drawbacks and in particular to allow a sharp reduction in the surface resistivity of a solid polymer part while retaining in the mass its elastic properties and avoiding the use of chemical agents which are detrimental to health.
- the inventors have for example found that the simultaneous presence of He + and He 2+ ions makes it possible to very significantly improve the surface antistatic properties of the polymers compared with known treatments where only He + or He 2 ions are used. + are implanted. They were able to show that a significant improvement was obtained for RHe less than or equal to 100, for example less than or equal to 20.
- the invention makes it possible to reduce the surface resistivity of a piece of solid polymer, and / or to eliminate the bonding of the dust or even to reduce the polarization of the surface by eliminating strongly polarized chemical groups such as OH, COOH. These functional groups can induce Van der Walls forces which have the effect of sticking ambient chemical molecules to the surface of the polymer.
- the invention also makes it possible to increase the chemical stability of the polymer by creating, for example, a permeation barrier.
- a permeation barrier can slow the propagation of ambient oxygen in the polymer, and / or delay the diffusion of chemical protective agents contained in the polymer to the outside, and / or inhibit the release of toxic agents contained in the polymer. outwards.
- solid means a polymer part produced by mechanical or physical transformation of a block of material, for example by extrusion, molding or any other technique adapted to transform a polymer block. Such transformations make it possible to obtain massive pieces of various shapes, for example three-dimensional parts, substantially two-dimensional parts such as profiled strips or plates, substantially unidirectional parts, such as son.
- the electronic component polymer supports to avoid electrostatic breakdowns that can destroy electronic components, or automotive dashboards to avoid the dust deposit.
- the solid piece of polymer may be a part of a piece of other material, for example reported on this piece of other material.
- PET Polyethylene terephthalate
- the multicharged, multi-energy ions are produced simultaneously by an electron cyclotron resonance ion source (ECR source).
- ECR source electron cyclotron resonance ion source
- the process is low energy, inexpensive and allows its use in an industrial setting without any environmental impact.
- the treatment of a polymer part is performed by simultaneous implantation of multicharged multi-energy ions.
- the latter are obtained in particular by extracting with single and single extraction voltage mono- and multi-charged ions created in the plasma chamber of an electron cyclotron resonance ion source (source RCE).
- source RCE electron cyclotron resonance ion source
- Each ion produced by said source has an energy that is proportional to its state of charge.
- the ions with the highest charge state therefore the highest energy, are implanted in the polymer part at greater depths.
- An implementation with an ECR source is fast and inexpensive since it does not require a high extraction voltage of the ion source. Indeed, to increase the implantation energy of an ion, it is economically preferable to increase its state of charge rather than increase its extraction voltage.
- the source is an electron cyclotron resonance source producing multi-energy ions which are implanted in the room at a temperature below 50 ° C and the implantation of ions of the implantation beam. is performed simultaneously at a depth controlled by the extraction voltage of the source.
- the ions excite during their passage the electrons of the polymer causing splits of bonds.
- covalentes which recombine immediately to generate, by a so-called crosslinking mechanism, a high density of covalent chemical bonds mainly consisting of carbons.
- Lighter elements such as hydrogen and oxygen are removed from the polymer during degassing.
- This densification in carbon-rich covalent bonds has the effect of superficially increasing the conductivity and reducing or even eliminating the superficial polar groups at the origin of the Van der Walls forces at the origin of the bonding.
- the crosslinking process is all the more effective as the ion is light.
- N nitrogen
- O oxygen
- Ne neon
- Ne argon
- Kr krypton
- Xe xenon

- the dose of multi-energy ion He + and He 2+ is between 5.10 14 and 10 18 ions / cm 2 , for example greater than or equal to 10 15 ions / cm 2 and / or less than or equal to 5.10 17 ions / cm 2 , or even greater than or equal to 5.10 15 ions / cm 2 and / or less than or equal to 10 17 ions / cm 2 ;
- the variation of a characteristic property of the evolution of the surface of a solid piece of polymer is determined, for example the surface resistivity of the polymer of a polymeric material representative of that of the piece to be treated; based on doses of multi-energy ions He + and He 2+ so as to determine a range of ion doses where the variation of the characteristic property chosen is advantageous and evolves in a differentiated manner in three consecutive zones of doses of ions forming said ion dose domain, with an evolution in the first substantially linear zone and reversible over a period of less than one month, an evolution in the second zone substantially linear and stable over a period of time greater than one month; the third constant and stable zone lasting more than one month and where the dose of multi-energy ions He + and He 2+ is chosen in the third zone of ion doses for treating the massive piece of polymer; reversible evolution (first zone) means that the resistivity decreases and then rises to recover its original value. This phenomenon is due to the persistence of free radicals after

It can be estimated that for energies of 100 keV, He 2+ travels an average distance of about 800 nm for an average ionization energy of 10 eV / Angstrom. For energies of 50 keV, He + travels an average distance of about 500 nm for an average ionization energy of 4 eV / Angstrom. The ionization energy of an ion is related to its crosslinking power.
- FIG. 2 represents, according to the DOD HDBK 263 standard, the resistivity values qualifying the electrostatic properties of a material.
- a polymer has insulating properties for surface resistivity values greater than 10 14 ⁇ / ⁇ (ZONE I), antistatic properties for surface resistivity values of between 10 14 ⁇ / ⁇ and 10 9 ⁇ / ⁇ (zone A) .
- the electrostatic dissipative properties appear for surface resistivity values between 10 5 ⁇ / ⁇ and 10 9 ⁇ / ⁇ (zone D) and conductive properties for values below 10 5 ⁇ / ⁇ (zone C)
- the resistivity measurement was carried out according to IEC 60093.
- the resistivity measurement technique used does not make it possible to measure resistivities greater than 10 15 ⁇ / ⁇ corresponding to the zone N, it saturates at 10 15 ⁇ / ⁇ .
- the abscissa axis corresponds to the time separating the treatment of the sample to the measurement of its surface resistivity.
- the y-axis corresponds to the measurement of the surface resistivity expressed in ⁇ / ⁇ .
- a first zone is distinguished for doses less than or equal to 10 15 ions / cm 2 , the surface resistivity decreases for less than a month by about 3 orders of magnitude (passing 1, 5.10 16 ⁇ / ⁇ to 5.10 12 ⁇ / ⁇ ) before returning to its original value around 1, 5.10 16 ⁇ / ⁇ (curve 1).
- the antistatic properties are ephemeral, the free radicals still present recombine with the oxygen and the ambient air.
- the antistatic properties (curve 2 and 3) strengthen to become dissipative of electrostatic charges (curve 4). For these doses, the resistivities remain constant over more than 140 days.
- the beam has a diameter of 15 mm and an intensity of 0.225 mA, the extraction voltage is about 35 kV.
- the abscissa represents dose in ions per unit area expressed in October 15 ions / cm 2.
- the ordinate axis represents the surface resistivity expressed in ⁇ / ⁇ .

- the ordinate axis represents the surface resistivity expressed in ⁇ / ⁇ .
- the resistivity measurement was carried out according to IEC 60093. From these curves, it appears that the reduction in speed by a factor of 2 has the effect of reducing by a factor of 10 the surface resistivity of the PC. Without wishing to be bound by any scientific theory, it may be thought that reducing the speed of the beam increases the surface temperature of the PC. This temperature strongly favors the recombination of the free radicals with each other, thereby promoting the formation of a dense and conductive layer of amorphous carbon. The heating also has the effect of expelling the residual gases produced by the ion-bombardment-induced splitting / crosslinking mechanisms.
- the inventors have deduced from this experiment that for any polymer treated with a beam of known diameter and power, there is a minimum speed of displacement of the beam causing a maximum reduction of the surface resistivity of the polymer without risk of degradation of the polymer under the effect of heat produced.
- the thermal degradation of the polymer has for signature a significant degassing followed by a rise in pressure at the extraction system of the source RCE. This rise in pressure results in electrical breakdowns.
- the extraction system is used to extract ions from the plasma from the ECR source to form the beam.
- the inventors recommend a test step which consists in progressively reducing the speed of the beam while retaining the other characteristics:
- the polymer thermally degrades under the effect of heat, when the rise in pressure measured by a gauge located both in the extraction system and in the treatment chamber, makes a jump of 10 "5 mbar in a few seconds The tests must be stopped immediately in order to keep only the beam displacement speed of the previous test.This jump of 10 -5 mbar in a few seconds or even less is the sign of a thermal degradation of the polymer.
- the treatment of at least one surface of a solid polymer part by implantation of helium ions He + and He 2+ has been carried out with He + and He 2+ multi-energy ions. , produced simultaneously by an ECR source.
- the treated polymers include the following: polypropylene (PP), polymethylacrilate (PMMA).
- the surface antistatic properties of a polymer are significantly improved from a dose greater than 5 ⁇ 10 15 ions / cm 2 , which represents a treatment speed of about 15 cm 2 / s for a Helium beam consisting of 9 mA of He + ion and 1 mA of He 2+ ions.
- the simultaneous implantation of helium ions can be done at varying depths, depending on the needs and the shape of the piece to be treated. These depths depend in particular on the implantation energies of the ions of the implantation beam; they may for example vary from 0.1 to about 3 ⁇ for a polymer. For applications where one looks for properties such as anti-gluing, for example, one could be content with a thickness less than one micron, reducing the processing times accordingly.
- the implantation conditions of the He + and He 2+ ions are chosen so that the polymer part retains its elastic mass properties by maintaining the workpiece at treatment temperatures of less than 50 ° C.
- This result can be achieved in particular for a beam with a diameter of 4 mm delivering a total intensity of 60 microamperes with an extraction voltage of 40 kV, moving at 40 mm / s on displacement amplitudes of 100 mm.
- This beam has a power per unit area of 20 W / cm 2 .
- the beam can have a diameter of 40 mm to maintain a pfd of 20 W / cm 2 .
