Abstract
The present invention is that a class contains the polypyrrole conducting polymer composite.It is by as the macromolecular material of matrix be distributed in this material surface and innerly formed as the polypyrrole of conductive component.Because the present invention selects polyamide-polyolefin fiber or film as matrix, earlier through tri-chlorination molten iron (or ethanol) solution-treated, make the polymeric amide part in the matrix polymer fully absorb iron trichloride, carry out gas-phase reaction with pyrrole monomer then, so the material electric conductivity that obtains is up to 10
0(ohmcm)
-1, higher 10～100 times than like product.The polyolefine part of matrix then plays enhancement, makes material keep the good mechanical performance, has remedied the deficiency of like product.
Description
The invention belongs to conducting polymer composite.This conducting polymer composite system is by substrate macromolecule material and be incorporated in polymer surface and innerly formed as the polypyrrole of conductive component.Its substrate macromolecule material is a polyamide-polyolefin complex.
For a long time, macromolecular material is used as ionogen by people always.In recent years, along with the development of electronic industry, aviation, sun power utilization, medical treatment, weaving and other sophisticated technology, urgent day by day for the demand of macromolecular material with conducting function.
Usually, conducting polymer composite is divided into two classes: conductive polymeric composite and structural conductive polymkeric substance.
The electroconductibility of conductive polymeric composite, the filler that depends on dope layer, metal level or sneak into.Itself or peel off because of conductive layer, shorten work-ing life; Or, reduce the Material Physics mechanical property because of adding conductive filler material.And specific conductivity is generally 10

-1Below.
The structural conductive polymkeric substance is meant polymer itself or has the polymkeric substance of conducting function behind overdoping.In this class material, polymer itself all has high conjugated π system.Up to the present, the most representative polysulfur nitride, polyacetylene, polyparaphenylene, polyaniline, polypyrrole, the Polythiophene etc. of mainly containing.Though this class conductive polymers has very high specific conductivity, all there is the deficiency of following several respects in major part: (1) specific conductivity is to the atmosphere instability, and along with the material increase of exposure duration in air, its specific conductivity obviously descends; (2) the above poor heat stability of room temperature; (3) this nearly all class conductive polymers all is insoluble infusible, can not use conventional method forming process.This unstable of conductive polymers and be difficult to the practical application that processing forming has seriously hindered this class material.
Polypyrrole is one of a few stable polymer.Because the moulding problem does not cause that for a long time people pay attention to.
Chinese patent [CN86101389] provides a kind of conducting polymer composite of polypyrrole, be (as cotton wool with non-conductive flexible-chain polymer, wool, silk, polymeric amide, polyester, polyolefine etc.) as matrix, with it at pyrroles (or other monomer such as thiophene, furans, indoles, imidazoles etc.) carry out swelling treatment in the solution, make solvent and monomer enter matrix polymer, and then can provide the ionogen iron trichloride of the negative ion that contends with (or iron potassium hydride KH, CAN, hydrogen peroxide etc.) handle in the solution, make the monomer molecule in situ polymerization that is absorbed in the matrix polymer, form a kind of conducting polymer composite material of two components.This material has overcome the shortcoming that as above polypyrrole is difficult to process, and that its weak point is a specific conductivity is low, is up to 10
-2(ohmcm)
-1Simultaneously, this processing can influence the mechanical property of matrix polymer.U.S. Pat 4,521,450,4,617,228, Japanese Patent JP 63-20361, JP-63-78403 etc. contain the polypyrrole conducting polymer composite, and its specific conductivity is also all 10
-2(ohmcm)
-1Below.
The objective of the invention is to obtain a kind ofly have 10
0(ohmcm)
-1The conducting polymer composite of specific conductivity and maintenance excellent mechanical performances.This material is made matrix with polyamide-polyolefin fiber or film, handles with liquor ferri trichloridi, again through the pyrrole monomer vapour phase polymerization, obtains containing the polyamide-polyolefin composite conducting material of polypyrrole.
The polypyrrole conducting polymer composite that contains of the present invention is that the selection polyamide-polyolefin complex is a matrix.This matrix is handled in water (or ethanol) solution of iron trichloride earlier, make matrix polymer absorb enough iron trichlorides, carry out gas-phase reaction with the pyrroles then, the polypyrrole of generation is evenly distributed in the body material, form the polycomponent conducting polymer composite material.
Material of the present invention is that a class contains the polypyrrole conducting polymer composite, and by as the macromolecular material of matrix be distributed in this material surface and innerly formed as the polypyrrole of conductive component, this class specific conductivity reaches 10
0(ohmcm)
-1The substrate macromolecule material of electro-conductive material be polyamide-polyolefin complex with definite shape.
Substrate macromolecule material of the present invention: the shape of polyamide-polyolefin complex is meant fiber or film.The polymeric amide part can be polyamide 6, polyamide 66, polyamide 6 10, polyamide 1010.The polyolefine part can be polyethylene, polypropylene, polyvinyl chloride, polystyrene.In the polyamide-polyolefin matrix material, the weight ratio of polymeric amide and polyolefine is: polymeric amide accounts for 10～80%, and polyolefine accounts for 90～20%.
Maximum characteristics of the present invention are that material electric conductivity can reach 10
0(ohmcm)
-1, higher 10～100 times than above-mentioned other method.In addition, polyolefine can not because matrix polymer adopts polymeric amide and polyolefinic matrix material, and polymeric amide can absorb iron trichloride.Like this, polyolefine has played enhancement, so material keeps the good mechanical performance.In addition, the present invention adopts vapour phase polymerization, has not only improved specific conductivity, and the simplification process, can be continuously produced, and reduces cost.
