  • Patent number: 10280534
    Abstract: A cured epoxy resin material is depolymerized by using a composition including a compound represented by the chemical formula of XOmYn (wherein X is hydrogen, alkali metal or alkaline earth metal, Y is halogen, m is a number satisfying 1?m?8 and n is a number satisfying 1?n?6), and a reaction solvent, wherein X is capable of being dissociated from XOmYn and Y radical is capable of being produced from XOmYn in the reaction solvent. It is possible to carry out depolymerization of a cured epoxy resin material, for example, at a temperature of 200° C., specifically 100° C. or lower, and to reduce processing cost and energy requirement. It is also possible to substitute for a reaction system using an organic solvent as main solvent, so that the contamination problems caused by the organic solvent functioning as separate contamination source may be solved and environmental contamination or pollution may be minimized.

  • Patent number: 9298114
    Abstract: Oxotitanium phthalocyanine nanoparticles in the crystal form of phase-Y (Y-TiOPc) having particle diameters of 2˜4 nm, preparation, and applications thereof are disclosed. The preparation method comprises the following steps: mixing a concentrated sulfuric acid solution of TiOPc with water or dilute sulfuric acid, or water or dilute sulfuric acid with a surfactant dissolved therein, or an aqueous solution of a low molecular weight organic compound to form a suspension or hydrosol; adding into the resulting suspension or hydrosol chlorinated hydrocarbons to extract TiOPc into an organic phase, so as to form a colloidal solution of Y-TiOPc nanoparticles; and then, washing and drying the above nanoparticles to give rise to a powder of the Y-TiOPc nanoparticles. Such a nanoparticle powder can disperse in chlorinated hydrocarbons to form stable colloidal solutions, thereby providing an alternative approach for solving the problem of poor dispersibility for Y-type TiOPc.

  • Patent number: 9249071
    Abstract: The invention provides methods for substituting polyaromatic hydrocarbons or polyheterocyclic compounds with perfluoroalkyl groups. The methods can include heating a polyaromatic hydrocarbon substrate or a polyheterocyclic compound substrate in the presence of a perfluoroalkyl iodide, typically in a closed system, wherein the heating is sufficient to bring both the polyaromatic hydrocarbons or polyheterocyclic compound, and the perfluoroalkyl iodide, into the gas phase, thereby allowing the substrate to react with the perfluoroalkyl iodide in the gas phase to form polyaromatic hydrocarbons or polyheterocyclic compounds having one or more perfluoroalkyl substituents. The methods allow for the creation of versatile libraries of novel perfluoroalkyl-containing derivatives that can serve as important building blocks and active components in biomedical, electronic, and materials applications.

    Abstract: Aspects describe phthalocyanine (Pc) molecules with peripheral modifications of its core (e.g., alkyl substituents) so that the Pc can self assemble, for example under vacuum sublimation, and form nanocrystals of a size on the order of nanometers. The Pc nanocrystals can be prepared, for example, by a simple vapor deposition method. Further aspects describe a polymer composite ink based Pc nanocrystals in a polymer matrix, which can be formed, for example, under a solution process approach. For example, the polymer matrix can be a different p-type conjugated polymer from the Pc nanocrystals, which are inherently p-type semi-conductors. This can increase the film formation ability and charge transport properties of the polymer composite ink. The polymer composite ink can be utilized, for example, in the fabrication of optoelectronic devices, such as photovoltaic devices and/or thin film transistors. The optoelectronic devices can exhibit high power conversion efficiency (PCE), for example 6-7 percent.
