Preparation method for graphene dye with far infrared function

Abstract

The invention discloses a preparation method for a graphene dye with a far infrared function. The preparation method comprises the following steps: taking a certain amount of graphene, coupling reagent and dispersing agent, pouring into a container at a certain ratio and mixing; stirring for 30-40min with a stirring rod; adding distilled water for regulating pH value of solution to 6-7 and then sealing and standing by; taking a certain amount of activated carbon powder and putting into a dryer under the temperature set at 200-250 DEG C. Solid grains of organic pigments are prevented from settling and agglomerating; a drug required by a stable suspension is formed; the settling and agglomerating of graphene are avoided and the uniformity of graphene is promoted; far infrared ceramic powderis capable of radiating a special ceramic material with a specific wavelength far infrared ray and is capable of accelerating the dissolution rate of activated carbon powder; the far infrared ceramicmicro-powder is added, so that a certain far infrared function is achieved, the mixing of graphene dye and far infrared ceramic micro-powder is accelerated and the purpose is achieved.

Description

technical field [0001] The invention relates to a method for preparing graphene dyes, in particular to a method for preparing graphene dyes with far-infrared functions. Background technique [0002] Generally, the wavelength that normal people most need to absorb is 4-14 μm. Products made of far-infrared rays combined with plastic materials penetrate into the subcutaneous tissue through far-red rays to generate thermal effects, thereby stimulating the activity of human body cells, effectively improving human blood circulation, providing tissue oxygen supply, improving metabolism, and enhancing immunity. Generally, it can play the role of health care, rehabilitation and self-assisted treatment at normal temperature. [0003] Graphene is a two-dimensional crystal, the biggest characteristic is that the movement speed of electrons in it reaches 1 / 300 of the speed of light, which far exceeds the movement speed of electrons in general conductors. This makes the electrons in gra...

Problems solved by technology

The common graphite is formed by stacking planar carbon atoms arranged layer by layer in a honeycomb shape. The interlayer force of graphite is weak, and it is easy to peel off each other to form thin graphite sheets. When the graphite sheets are peeled off After forming a single layer, this single layer with a thickness of only one carbon atom is graphene. Graphene is not only the thinnest known material, but also very strong and hard; as a simple substance, it transmits electrons at room temperature faster than It is known that the conductors are fast, but the existing dyes made of graphene do not have far-infrared functions, and a method of combining the two is needed
