preparation example Construction

[0016] The preparation method of fluorine-containing and hydroxyl modified fullerene C60 is:

[0017] First, the fullerene C60 was acidified with concentrated sulfuric acid (98%), slowly added to pure water and stirred to dissolve, and then alkalized with NaOH solution to precipitate, filtered and washed repeatedly with methanol until neutral. Dry to obtain hydroxyfullerene C60; finally, add hydroxyfullerene C60 to pure water to dissolve and stir, add perfluoroalkanol compound, stir evenly, add ammonium persulfate and triethylamine, heat for reaction, wash and dry The fluorine-containing and hydroxyl-modified fullerene C60 was obtained. The above steps need to be filled with inert gas protection.

Embodiment 1

[0019] A fullerene-containing photoelectric semiconductor coating formulation is as follows, each by mass fraction:

[0020] Vinyl resin: 80 parts;

[0021] Melamine resin: 20 parts;

[0022] Hole transport material: 50 parts;

[0023] Electron transport material type I, fluorine-containing and hydroxyl-modified fullerene C60: 3 parts;

[0024] Electron transport material type II: 27 parts;

[0025] Charge generating material: 3 parts;

[0026] Antioxidant 1010: 5 parts;

[0027] Solvent (tetrahydrofuran): 400 parts.

[0028] The ratio of electron transport material type I to the sum of electron transport material type I and electron transport material type II is 1 / 10. After the materials are completely mixed and dissolved, they are ground on a grinder for 2 hours. The size is 1mm zirconium beads, and the filling volume of the chamber is 80%. , the obtained liquid was filtered with a 5-micron filter, and a film was coated on the aluminum base by a ring coating method, an...

Embodiment 2

[0030] The manufacturing method of this example is the same as Example 1, except that the ratio of electron transport material type I to the sum of electron transport material type I and electron transport material type II is changed from 1 / 10 to 0.5 / 10, that is, fluorine-containing and hydroxyl-modified rich Lene C60: 1.5 parts, electron transport material type II: 28.5 parts, and photosensitive drum E2 was prepared in this way.

Abstract

The invention discloses a formula of a fullerene-containing photoelectric semiconductor coating. The fullerene-containing photoelectric semiconductor coating comprises the following components in parts by mass: 50-100 parts of vinyl chloride-vinyl acetate resin, 5-30 parts of melamine resin, 35-70 parts of a hole transport material, 20-40 parts of an electron transport material I, 20-40 parts of an electron transport material II, 2-10 parts of a charge generating material, 1-5 parts of an antioxidant and 300-500 parts of a solvent. The fluorine-containing photoelectric semiconductor coating has the advantages that the fluorine-containing and hydroxyl-containing modified fullerene C60 is added and is used for a positive charging type photosensitive drum coating, and excellent electron transmission characteristics and high wear resistance are obtained.

Description

technical field [0001] The invention relates to the technical field of photoelectric semiconductor coatings, in particular to a fullerene-containing photoelectric semiconductor coating formulation. Background technique [0002] Organic photosensitive drum is a kind of optoelectronic semiconductor device that can make light-generated carriers form and migrate under laser irradiation. It is the core photoelectric conversion in modern office equipment such as laser printers, digital copiers, laser fax machines and multi-function machines It is a highly integrated and high value-added organic optoelectronic semiconductor information product integrating modern functional materials and modern advanced manufacturing technology. [0003] The organic photosensitive drum is mainly composed of a cylindrical aluminum substrate and an organic photosensitive material coated on the outer layer of the substrate. The aluminum substrate is generally made of A6063 or A3003 aluminum, which is ...
