< graphene fiber >

The examples of successful synthesis of graphene fibers and their important role in some specific applications have stimulated research interest in recent years, and graphene is a new material with a single-layer honeycomb structure composed of carbon atoms and a structural basis for other dimensional carbon materials. Graphene has many unique properties, such as high electron mobility, high thermal conductivity, good elasticity and stiffness, etc. Therefore, assembling graphene into a macroscopic functional structure such as a fiber is an important way to realize practical application of graphene.

The graphene has the effect of far infrared rays. 1. Improving blood circulation: far infrared ray penetrates into subcutaneous tissue of human body to raise the temperature of subcutaneous deep skin, dilate capillary, promote blood circulation, revitalize enzyme, strengthen blood and cell tissue metabolism, and help cell recovery and improve anemia. Far infrared rays expand microvessels, promote blood circulation to lower hypertension, and improve hypotension symptoms. 2. Improving the joint pain: the far infrared ray deep penetration can reach the deep part of muscle joints, so that the body is warm, the muscles are relaxed, the oxygen and nutrient exchange of a capillary network is driven, and the effects of eliminating fatigue substances, lactic acid and other aging wastes accumulated in the body, eliminating internal swelling and relieving ache are excellent. 3. Modulation of autonomic nerves: the autonomic nerve mainly regulates the function of internal organs, and the continuous tension of the autonomic nervous system of a human in an anxiety state can cause the reduction of immunity, headache, dizziness, insomnia, hypodynamia and cold limbs. The far infrared ray can adjust the autonomic nerve to keep the best state, and the symptoms can be improved or removed. 4. Skin care and beauty treatment: can metabolize fatigue and aging-causing substances, such as lactic acid, free fatty acid, cholesterol, and excessive subcutaneous fat, directly from skin without passing through kidney due to the activation of hair follicle opening and subcutaneous fat. Can make skin smooth and tender. The physical therapy effect of the far infrared ray can improve the heat energy in the body and activate cells, thereby promoting the metabolism of adipose tissues, burning and decomposing, consuming the redundant fat and further effectively losing weight. 5. And (3) metabolism enhancement: by the heat effect of far infrared, the vitality of cells can be increased, the mechanism of nerve body fluid is adjusted, metabolism is enhanced, and the matter exchange in the body is in a stable state. 6. Improving the immune function: improving phagocytic function of macrophage, regulating cellular immunity and humoral immunity, and promoting health. 7. Activation of the biomolecular activity: the far infrared photons enable the molecular energy level of organisms to be excited to be in a higher vibration energy level under the action of the 2-6 micron far infrared photons, so that the activity of biomacromolecules such as nucleic acid protein and the like is activated, the functions of regulating activities such as organism metabolism, immunity and the like of the biomacromolecules are exerted, the recovery and balance of the organism functions are facilitated, and the purposes of preventing and treating diseases are achieved. 8. Anti-inflammatory action: a) the far infrared heat action eliminates the pathological process of inflammation through the response reaction of nerve body fluid, accelerates the original destroyed physiological equilibrium state to restore to normal, improves the disease resistance of local and whole bodies, activates the function of immunocyte, strengthens the phagocytic function of leucocyte and reticular skin cell, and achieves the aim of diminishing inflammation and inhibiting bacteria. b) The infrared heat effect increases the skin temperature, reduces the sympathetic nerve sensing ability, releases vasoactive substances, expands blood vessels, accelerates blood flow, improves blood circulation, enhances tissue nutrition, activates tissue metabolism, improves oxygen supply of cells, improves the blood and oxygen supply states of a focus area, enhances the regeneration ability of the cells, controls the development and localization of inflammation, and accelerates the repair of the focus. c) The far infrared heat effect improves microcirculation, establishes collateral circulation, enhances the stability of cell membrane, regulates the concentration of ions, improves osmotic pressure, accelerates the discharge of toxic substance metabolites, accelerates the absorption of exudates, and leads to the regression of inflammatory edema. 9. Improving a circulating system: the comprehensive and deep penetration of far infrared ray irradiation is the only physical therapy mode which can take care of the microcirculation tissue system which is not counted inside and outside the whole body. After the microcirculation is smooth, the systolic pressure is reduced, the oxygen and nutrient supply is sufficient, and the body is naturally light and healthy. Strengthening the liver function: the liver is the largest chemical plant in the body and is the purifier of blood. The deep effect of in vivo heat caused by far infrared ray irradiation can activate cells, improve tissue regeneration capability, promote cell growth, strengthen liver function, improve liver detoxification and toxin expelling effects, keep the internal organ environment in a good state, and be the best disease prevention strategy. 10. The analgesic effect is as follows: the thermal effect of infrared reduces the excitability of nerve endings; improving blood circulation, eliminating edema, and relieving chemical and mechanical irritation of nerve terminal; the far infrared heat action improves the pain threshold, and the pain relieving function is realized by the far infrared heat action. The biological effect of far infrared ray, in addition to the above mentioned thermal effect, has many other important biological effects, such as the relationship between far infrared ray and life, the improvement of microcirculation by infrared ray, the activation of water molecules, the activation of tissue cells, and other important functions.
