Embodiment 1

[0036] α-ET 2 I 3 Dissolved in dimethylformamide, formulated as 0.5% (weight percent) α-ET 2 I 3 dimethylformamide solution. Pipette 1 mL of the solution and slowly drop it into 20 mL of deionized water under ultrasonic dispersion, continue ultrasonic dispersion for 15 min after the addition, centrifugal sedimentation, and vacuum dry at room temperature. The resulting particle size ranges from hundreds of nanometers to several microns.

Embodiment 2

[0038] As described in Example 1, except that α-ET 2 I 3 The solution was dispersed in a 0.5% aqueous solution of sodium lauryl sulfate. The particle size obtained is in the range of 100nm-400nm.

Embodiment 3

[0040] As described in Example 2, except that α-ET 2 I 3 The solution was dispersed in a 1% aqueous solution of sodium lauryl sulfate. The particle size obtained is in the range of 20nm-60nm.

Abstract

Metal ET salt nanopowders and their manufacture method are disclosed. A process is carried out by: re-depositing to dispensing compounds, dissolving electric charge transfer salt with ET as electron donor, which is obtained by chemical oxidation and electrochemical method, in a solvent, dispersing in another solvent or solution supersonically, and drying to get nano crystals. The method is simple. Surfactants or polymers are used to prevent agglomeration. Their sizes are between 20-100 nm without agglomeration. They can directly disperse and deposit to form metallic solution, so as to predetermine compositions and crystal models of nano-granules.

Description

(1) Technical field [0001] The invention relates to a method for preparing nanometer powder of synthetic metal ET (ethylene disulfide tetrathiafulvalene, BEDT-TTF) salt. Specifically, it relates to a preparation method of a charge-transfer salt nanopowder with good dispersibility, no agglomeration, and uniform particle size, which uses ET as an electron donor, and belongs to the field of nanomaterials. (2) Background technology [0002] Due to its surface effect, small size effect, and quantum confinement effect, nanomaterials have different physical properties such as optics, magnetism, and electricity from their large-scale bulk materials, which has aroused widespread interest in the study of nanomaterials. For decades, a lot of work has been done on the preparation and performance of inorganic metals, metal oxides, and inorganic salt nanomaterials. Due to the diversity of organic compounds and the designability of molecules, it is possible to tailor the molecules of orga...
