Graphite fever
The graphite powder is distributed evenly in organic solvents using ultrasound and mixing methods, receiving graphite solution at concentrations of 0. 05 mg/ml ~0. 5 mg/ml, graphite is covered evenly on organic filters or water filters by filtering, and graphite membranes and graphite membranes are separated by mechanical stripping, leaching or organic solvent solubility, and graphite membrane is obtained by adding electrodes to the graphite membrane membrane, which can produce heat by applying electric pressure. Owing to the unique bivinami structure of graphite, the properties of large thickness and high surface area, the above-preparation process has resulted in the formation of an evenly connected conductive network between graphite tablets, which produces higher heat at lower voltage (1-10v)。
It is mainly based on the efficient heat transfer capacity of graphene, which has a heat coefficient higher than that of metals such as copper, aluminium, iron, etc., and is second only to thermal tubes, but graphenes do not have the same technical quality as a heat tube, so that they can be formed in various shapes as required, such as heat transfer boards, heat transfer tubes and, of course, a heat membrane。
Led, wired to graphite. They simply placed graphite in the copper chloride solution for observation. The led light's on. In fact, they need six graphite circuits to form a cascade so they can generate the 2vs needed to light up the led light and get the picture。
The situation here is that the copper ion has a double positive charge, and the speed of passing through the solution is about 300 metres per second, because the solution is hot at room temperature. When the ion crashes heavily into the graphite belt, the collision produces sufficient energy to remove the graphite from the in situ electrons. Electronics have two options: to leave the graphite belt, to combine with copper ion, or to cross the graphite into the circuit。
Originally, the flow of electronics is faster in graphite than it passes through the solution, so the electron naturally chooses the path through the circuit. It is this that lighted the led lamp “the electronics released are more inclined to pass through the graphite surface than into electrolyte. That's how equipment generates voltage
Therefore, the energy generated by this device comes from the heat in the surrounding environment. They can raise the current, only heat up the solution, and also use ultrasound to accelerate the copper ion. Graphite batteries can be operated for 20 days on their surrounding calories alone. But there is also an important question mark. Another assumption is that some chemical reaction produces currents, like ordinary batteries。
Use of graphite
The application of graphite is extensive. Based on graphite's super thinness and strength, graphite can be widely used in various fields, such as super light bulletproof vests, super thin super-light aircraft material, etc. By virtue of its superior conductivity, it also has great application potential in the field of microelectronics. There is a potential for graphite to become a silician substitute for super-micro transistor tubes to be used in the production of future supercomputers, and a higher rate of electronic transport of carbon can give future computers a higher speed. In addition, graphite material is a good modified agent and can be used as an electrode material aid in new energy areas such as super capacitors and lithium ion batteries because of their high conductivity and high surface area。
Thermoline application
Thermal graphite (tcgs-s), also known as graphite dispersors, is an entirely new heat-resilient heat material with a unique crystal-dissemination orientation, a smooth heat-resilient heat along both directions, a super-high-conductive heat energy in the 150-1500 w/m-k range within the plane, and a layer structure that is well adapted to any surface to shield heat sources and components while improving the performance of consumer electronics. Its molecular structure is illustrated below:
In the area of graphite flexible distillation, the west-west coaling of the central college has made two major advances this year. Previously, the institute had studied thermal evolution mechanisms of graphite membrane oxide during the carbonation process and obtained high performance thermal reduction of graphite membrane oxide. They have also been successful in developing high-conducted thermal graphite/carbon fibre flexible compound film with teams associated with the university of chinghua and the metal institute of the central college。
The assembly of nanography-molecene macros into thin membrane materials while maintaining its nanoeffects is an important way to scale applications. The shanxi coalification institute and related units build integrated carbon/carbon membranes through self-assembly technology. This carbon thin film has a multi-stage structure similar to steel condensed concrete with a thickness of between 10 ~ 200 m and a room temperature orientation of up to 977 w/m k and a stretch strength of more than 15 mpa. The study addressed the problem of graphite-conductive thermal application and was a breakthrough in the graphite field. Prepulsion with graphite oxide is readily available for membrane material, but this material requires thermal treatment to restore its conductive/conductive performance. Research by the shanxi coalization institute shows that 1000°c is the key point for membrane performance change, where the membrane performance changes. This finding not only addresses the underlying scientific problems of the graphite thermal chemical transformation, but also provides a basis for the scalable preparation of the graphite thermal film。
The graphite-based thin membrane can be used as flexible, bulk-oriented materials to meet the dispersion needs of high power, high-intensity systems such as led lighting, computers, satellite circuits, laser weapons, handheld terminals, etc. These findings provide an entirely new perspective for the design of structural/functionally integrated carbon/carbon composite materials。
