Definitions
- the present invention relates to the manufacture of conductive composite materials electricity containing polyaniline.
- Films of this type can be used in particular in electrostatic shielding or deicing windows.
- This threshold depends strongly on the morphology of the conductive phase. So when the phase conductor consists of carbon black or metals, the percolation threshold is usually very high and very often above 0.5. However, we have recently made composite materials whose conductive phase is formed of carbon black, which have a very lower percolation threshold (0.4% by weight), as described by Gubbels et al. in Macromolecules, 28, 1995, pp. 1559-1566.
- phase conductor consists of a conductive polymer
- phase conductor can reach lower percolation thresholds in using manufacturing techniques from a solution or manufacturing techniques by hot pressing of a mixture of polymers in the state solid.
- US-A-5,232,631 discloses the manufacture of composite materials from a solution of the insulating polymer forming the host matrix and of a conductive polyaniline in a solvent.
- polyaniline is first reacted with a appropriate protonant that makes it possible to make it soluble in a suitable organic solvent.
- a suitable organic solvent we use then the solution to form a film by casting and evaporation of the solvent. We can reach with these very low percolation thresholds and high conductivities.
- EP-A-0 643 397 discloses the manufacture of conductive composite materials also comprising a polymer host matrix insulation in which is distributed a polymer conductor constituted by a polyaniline, which is obtained by hot compression molding of a mixture of the conductive polymer and the insulating polymer to which usually adds a plasticizer.
- polyaniline can be protonated by an agent organic protonant and compatibilizer can be constituted by an aromatic compound which, during the material manufacturing, dissolves polyaniline conductive and forms a strong molecular association with it, and on the other hand ensures compatibility between the polyaniline and the insulating polymer.
- the present invention specifically relates to compositions for the manufacture of a material conductive composite from solutions, which allow to obtain high conductivities with smaller amounts of conductive polymer.
- the presence of a plasticizer the insulating polymer allows so unexpectedly to lower the percolation threshold of the composite material and to obtain conductivities high.
- the plasticizer allows not only to give flexibility to the polymer insulation, but also to prevent training of polyaniline aggregates by weakening the forces adhesion between the polyaniline grains. This leads to better dispersion of polyaniline in the host matrix of insulating polymer and promotes the formation of a continuous network of polyaniline conductive in the composite. This allows, as we will see below, to lower the percolation threshold of the composite material by a factor of 10, this one being for example greater than 0.04 in the absence of plasticizer and becoming equal to about 0.004 with the plasticizer.
- the Insulating polymers used are polymers made generally in the plasticized state like polyvinyl chloride and polymers cellulose.
- cellulose derivative such as acetate of cellulose.
- the plasticizers used are chosen from the usual plasticizers for these types of polymers.
- plasticizer a mixture of dimethyl phthalate, phthalate diethyl and triphenyl phosphate.
- Conductive polyanilines used in the invention are of the emeraldine-salt form. They may be substituted or unsubstituted.
- Polyanilines can also be used substitutes such as those described in the EP-A-0643397 and US-A-0 532 631.
- a polyaniline is used protonated by a protonating agent capable of promoting the dissolution of the polyaniline in the solvent used.
- protonating agents of this type include a acid function and hydrocarbon chains their conferring a surfactant character and making them compatible with organic solvents generally used, thereby promoting the dissolution of polyaniline in the solvent.
- protonating agents include: monoesters and diesters aliphatic and / or aromatic phosphoric acid, for example the alkyl and / or aryl esters of phosphoric acid, arylsulphonic acids and arylphosphonic acids.
- the protonating agent is chosen in the group consisting of camphorsulfonic acid, phenylphosphonic acid, dibutyl phosphate and dioctyl phosphate.
- the solvent organic can also be of different types but phenol solvents are generally preferred. such as cresols, and especially meta-cresol.
- compositions of the invention can be used for the manufacture of composite materials, especially in the form of conductive flexible films, highly transparent, by pouring the solution, followed by evaporation of the solvent.
- the composition is prepared in mixing a first solution of polyaniline protonated in the solvent to a second solution in the same solvent of the insulating polymer and the plasticizer.
- the invention also relates to an electrically conductive composite material obtained by this process, which comprises a cellulose acetate matrix in which are distributed a protonated conductive polyaniline and a plasticizer consisting of a mixture of dimethyl phthalate, phthalate and diethyl and triphenyl phosphate, the material having an electronic conductivity of 10 -6 to 10 S / cm.
- the polyaniline is protonated by phenylphosphonic acid.
- Figures 1 to 4 are graphs illustrating the conductivity of composite materials conductors, obtained by the process of the invention in depending on their polyaniline content; figures 1 at 4 correspond to the use of various agents protonants.
- a material is prepared composite according to the invention, using as cellulose acetate insulating polymer, as polyaniline of emeraldine protonated by phosphate dioctyl acid and as a plasticizer a mixture of dimethyl phthalate, diethyl phthalate and triphenyl phosphate.
- the protonation of this polyaniline is carried out by introducing 500 mg of polyemeraldine and 891 mg of di-isooctyl acid phosphate in 100 g of m-cresol. The protonation reaction is carried out for one week at room temperature with vigorous stirring.
- the conductivity of the films thus obtained measured using the standard four-point technique is 7 ⁇ 10 -2 S / cm.
- the conductivity of the film obtained under these conditions is less than 10 -10 S / cm.
- plasticizer significantly lowers the threshold of percolation.
- Example 2 The same procedure as in Example 1 is followed to prepare the solution of protonated polyaniline in m-cresol and the solution of cellulose acetate and plasticizer in m-cresol, but 2 g of the solution of cellulose acetate and plasticizer containing 304 mg of cellulose acetate and plasticizer with 0.6158 g of the polyaniline solution, or with 2.09 mg of emeraldine (estimated in unprotonated form).
- the films obtained from this composition have an emeraldine content of 0.7% by weight (estimate in unprotonated form).
- the conductivity of the film measured as before is 3.10 -3 S / cm.
- Example 2 The same procedure as in Example 2 is followed, except that the cellulose acetate solution does not contain plasticizer. A film having a conductivity of less than 10 -10 S / cm is thus obtained, which confirms the results obtained in Example 1 on the beneficial effect of the plasticizer.
- Figure 1 illustrates the results obtained, that is to say the conductivity of the composite material (log ⁇ ) depending on the polyaniline content (in% in weight).
- Example 2 We follow the same procedure as in Example 1, but it is used as protonating agent phenylphosphonic acid and mixing the solutions so as to have polyaniline contents in the material from 0.5% to 1.8% by weight.
- Figure 2 shows the conductivity of obtained material (log ⁇ ) according to its content in polyaniline (in% by weight).
- Example 3 we follow the same mode only in Example 1, but it is used as protonating agent di-n-butyl phosphate and one mix the two solutions to have levels in polyaniline ranging from 0.5 to 11% by weight.
- the conductivity of the material obtained (log ⁇ ) as a function of its content of polyaniline (% by weight) is given on the figure 3.
- Figure 4 illustrates the conductivity of material (log ⁇ ) according to its content in polyaniline.
- the percolation thresholds are ten times higher, for example f c> 0.04 in this das.
- Another very interesting property of the movies of composite material obtained in the examples above, is that they retain excellent flexibility plasticized cellulose acetate.
