Abstract: The present invention relates to the technical field of n-type semiconductor materials. Disclosed are an n-type conjugated polymer, a preparation method therefor, and a use thereof. In the method, using a solvent as a reaction medium, a reaction monomer is reacted under the action of a substance having oxidability to obtain an n-type conjugated polymer. The n-type conjugated polymer comprises one or more polymerization units, and the polymerization unit are of a structure of formula (I) and/or a structure of formula (II), and/or in an enol-type transformation form corresponding thereto. According to the present invention, an aromatic diketone substance having active methylene is a raw material, and is subjected to a direct polymerization reaction by means of the substance having the oxidability. The reaction does not require a noble metal for catalysis, and the n-type conjugated polymer is not sensitive to the reaction atmosphere, has a simple process and low costs, and is suitable for commercial applications. The n-type conjugated polymer of the present invention has excellent electron transport capability, higher conductivity, and better electromagnetic wave shielding effect. The n-type conjugated polymer of the present invention is applied to an organic optoelectronic device, and can achieve an excellent photoelectric effect.

Abstract: Boron nitride nanotube (BNNT)-polymide (PI) and poly-xylene (PX) nano-composites, in the form of thin films, powder, and mats may be useful as layers in electronic circuits, windows, membranes, and coatings. The processes described chemical vapor deposition (CVD) processes for coating the BNNTs with polymeric material, specifically PI and PX. The processes rely on surface adsorption of polymeric material onto BNNTs as to modify their surface properties or create a uniform dispersion of polymer around nanotubes. The resulting functionalized BNNTs have numerous valuable applications.

Abstract: Disclosed are thermally conductive quinoid-type conjugated polymer thin films. One such film comprises conjugated poly(3-hexylthiophene) (P3HT). The thin films can be fabricated using oxidative chemical vapor deposition (oCVD), which offers unique advantages for integrating polymer films into various devices. By avoiding the use of solvents in the deposition of monomers and oxidants and undesirable solvent-derived surface-tension driven effects, such as dewetting, the oCVD coatings can conformally coat complex geometries, can be scaled to large areas, and can be fabricated at relatively low substrate temperatures on electrically insulating substrates. Disclosed is the formation of ordered polymer structures with rigid backbones achieved by oCVD with stacking in the transverse direction via π-π interactions. P3HT films with record-high thermal conductivity of 2.2 W/m-K near room temperature have been prepared.

Abstract: The method of making a pyrrolo bisthiazole homopolymer starts with dissolving a dibrominated pyrrolo[3,2-d:4,5-d′]bisthiazole monomer having the formula: where R is an alkyl group, in anhydrous tetrahydrofuran (THF). Then, the solvated monomer is treated with 1 equivalent of a Turbo-Grignard reagent complex having the formula iPrMgCl.LiCl at 0° C. to form a reaction mixture. The reaction mixture is stirred for 1 hour at room temperature, and after stirring, the reaction mixture is refluxed for 24 hours. A conjugated homopolymer product having the formula: where n is the number of repeating units of pyrrolo[3,2-d:4,5-d′]bisthiazole, is recovered from the reaction mixture. The PBTz-based homopolymers showed broad absorption from 450 to 850 nm in thin film and excellent photochemical and thermal stability, making the polymers suitable for lightweight, low cost plastic electronic devices.
