Poly(aryleneethynylene) polymers for exfoliating and dispersing/solubilizing nanomaterial are provided herein. The poly(aryleneethynylene) polymers have unit monomer portions, each monomer portion having at least one electron donating substituent thereby forming an electron donor monomer portion, or at least one electron withdrawing substituent thereby forming an electron accepting monomer portion. Such polymers exfoliate and disperse nanomaterial without presonication of the nanomaterial.
Abstract:
The invention provides a structured material characterized in having, on a substrate (11), a layer (12) having tubular (13) pores positioned uniaxially parallel to the interface of the substrate and the layer and supporting a conductive polymer material (14,21) having a function of a surfactant (22) therein. The invention also provides a method for producing the above structure material characterized by the steps of providing a substrate having the anisotropy on a surface, applying a solution containing a surfactant having a functional group for polymerization in the molecular structure, a solvent therefor, and a solute different from the surfactant to the substrate, and a step of standing for a predetermined time for causing the surfactant to assemble in a predetermined direction based on the anisotropy of the substrate.
Abstract:
A conductive organic thin film which is made up of organic molecules each having at one end a terminal bonding group bonded to a substrate surface by covalent bonding and having a conjugated bond group which is present anywhere in the organic molecule and has been polymerized with other molecules and a polar functional group which contains no active hydrogen atom and is present anywhere between the terminal bonding group and the conjugated bond group, the organic molecules being oriented and the conjugated bond groups having been polymerized to form a polymer and a conductive network. The conductive organic thin film in an undoped state has a conductivity ( rho ) as measured at room temperature (25 DEG C) of 5.5x10 S/cm or higher, preferably 1x10 S/cm or higher. It has a far higher conductivity than metals such as gold and silver. In particular, a polypyrrole or polythienylene film formed by electrolytic oxidative polymerization and based on conjugated bonds has a high conductivity.

Abstract:
Patterned conducting polymer surfaces exhibiting excellent properties may be prepared by: (a) forming a surface of a conducting polymer on a surface of a substrate; (b) forming a surface of a blocking material on the surface of the conducting polymer in a patternwise fashion, to obtain a first patterned surface containing regions of exposed conducting polymer and regions of blocking material; (c) treating the first patterned surface with an agent which: (i) removes the conducting polymer from the regions of exposed conducting polymer; (ii) decreases the conductivity of the conducting polymer in the regions of exposed polymer; or (iii) increases the conductivity of the conducting polymer in the regions of exposed conducting polymer; and (d) removing the blocking material to obtain a second patterned surface containing an exposed pattern of conducting polymer.

Abstract:
A thin electroconductive film is formed by irradiating a shaped article of chlorinated vinyl polymer (1) with a pulsed light (7) having a pulse duration of not greater than 100 nsec., a fluence of above about 15mJ/cm /pulse and below that at which the polymer is subject to ablation, a wavelength of from about 190 to about 300 nm, and repetition rate of above about 1 Hz and below that at which the polymer is subject to deformation and/or decomposition by a thermal effect, under vacuum or in an oxygen-free atmosphere (5) thereby irradiating the article with total photon numbers of at least 1 x 10 /cm without substantially causing photo-crosslinking, oxidation or cleavage of the backbone chain. The invention does not use materials other than the starting polymer such as solvents or strong bases that can contaminate the thin film during a dehydrochlorination, so there is no need to remove solvents after reaction and no residual salts will be formed in the dehydrochlorination.
