Problems solved by technology

[0018] The primary particles are arranged and oriented in a preferred direction from the beginning anyway, but since the primary particles (nanoparticles) of conductive polymers and organometallics available so far are basically isotropic, it has not been possible to disperse them by stretching until now. Bulk-deposited flakes, films or fibers to increase conductivity (and thus cannot increase conductivity by stretching the product)

[0044] Examples of intrinsically conductive polymers or organometallics according to the invention are those mentioned at the beginning of the description. In particular the following examples: polyaniline (PAni), polythiophene (PTh), poly(3,4-ethylenedioxythiophene) (PEDT), polydiacetylene, polyacetylene (PAc), polypyrrole (PPy), Polyisothienylene (PITN), polyheteroarylene vinylene (PArV), where the heteroarylene group can be, for example, thiophene, furan or pyrrole, polyparaphenylene (PpP), polyphenylene sulfide (PPS) , polyperinephthalene (PPN), polyphthalocyanine (PPc) and others, as well as derivatives thereof (which are formed, for example, from monomers substituted with side chains or groups), copolymers thereof and physical mixtures thereof. Particular preference is given to polyaniline (PAni), polythiophene (PTh), poly(3,4-ethylenedioxythiophene) (PEDT), polythienothiophene (PTT) and derivatives thereof. Preferred binary mixtures of intrinsically conductive polymers...

Abstract

The present invention relates to a conductive polymer or organic metal which is characterized in that nanoscopic particles formed from same with a particle size of less than 100 nm have an anisotropic morphology which is not spherical and has a length-to-diameter (“L / D”) ratio greater than 1.2. The invention also relates to a process for the preparation of such polymers and their use in the preparation of shaped parts, self-supporting foils or coatings with electrical conductivity, in particular on anisotropic substrates or in anisotropic media and fields.

Description

technical field [0001] The present invention relates to electrically conductive polymers composed of particles with anisotropic morphology, a process for their preparation, and their use for the production of shaped parts (moldings), sheets or coatings. Background technique [0002] The terms conducting polymer, as well as "intrinsically conducting polymer" or "organometallic" are used to describe substances derived from low molecular weight compounds (monomers), which are oligomers obtained by at least polymerization and thus contain at least 3 Linked monomer units, which in the neutral (non-conducting) state have a conjugated π-electron system and can be converted to an ionic form by oxidation, reduction or protonation (often described as "doping"), are conductive. Conductivity of at least 10 -7 S / cm. [0003] In the case of doping by oxidation, for example iodine, peroxides, Lewis acids and protic acids are used as dopants, or in the case of doping by reduction, for exa...
