Graphene fever painting
Graphene heating painting uses' black technology' graphene high conductivity composite film as heating core, and the application of graphene heating film in heating painting is very outstanding and excellent. The heating speed is extremely fast, the painted surface temperature can reach tens of 100℃ in one minute, and its electrothermal conversion rate is close to 100%. In addition to the application of graphene heating film, the picture of heating painting is made of special technology and materials, which not only has decorative aesthetic feeling, but also releases far-infrared light waves beneficial to human health when heating, and the thermal radiation rate is above 87%, which is incomparable to any other materials at present. Let the indoor human body be like being in a windless "warm sun in winter", which has both heating and health care functions. Different from air conditioners, heaters, floor heating and other traditional heating equipment, graphene heating painting is more comfortable, more energy-saving, non-drying, noise-free, oxygen-deficient and pollution-free, and it is a classic innovation of science and technology to change life.
Application scenario

Graphene heating suit
In addition to covering the body to keep warm, traditional clothing has only brand value, and few high-tech products appear. Through technical research, Dr. Zhiene independently developed a high-tech intelligent heating suit in the application field of graphene heating film for people in extremely cold areas, outdoor people in winter and spring, people with deficient constitution and people who love beauty in winter. The graphene composite film is made into an efficient conductive, thermal conductive and flexible heating inner core, which is perfectly combined with daily clothes. The application of graphene heating film has brought revolutionary changes to traditional clothing. The heating rate is extremely fast, reaching 40 degrees Celsius and above in a few seconds, and the constant temperature can be controlled at a safe low pressure (5V) for 3 to 5 hours. Through the three-speed intelligent temperature control, the wearer can adjust the inner core of the garment to a comfortable temperature. Graphene also efficiently releases 8~ 15μm band far-infrared life light waves beneficial to human health during heating, keeping warm and keeping healthy. It has brought better enjoyment to people's lives, and it has been warm and portable since winter, with both grace and temperature.
Application scenario
Workers who need to keep warm outdoors, such as railways, electric power, traffic police, actors and border guards in cold areas, can carry out customized development of industrial clothing. Warm-keeping needs of the elderly, the weak and the people who are afraid of cold in winter and spring. Business and beauty lovers need "elegance and warmth" in winter.

Graphene physical therapy protective gear
Through the application technology of graphene heating film, using the high-efficiency conductivity and thermal conductivity of graphene flexible heating film material, ultra-low safe voltage (5v) is used for power supply, and the heating temperature rises rapidly. Electrothermal emissivity is as high as 87%, which releases 8- 15μ m far-infrared life light wave suitable for human health, and has both warm-keeping and physical therapy functions. The application of graphene heating film is designed and manufactured for many people suffering from cold in winter and spring, rheumatism, neck, shoulder and waist soreness. Intelligent temperature control is used to adjust the temperature to a comfortable feeling, and human health data information is collected through intelligent sensing to realize multiple functions such as heating and heat preservation, sports protection, rehabilitation physiotherapy and health management. Bring comfortable and intimate feelings to the sub-health population with deficiency and cold constitution and the population after chronic disease rehabilitation. Smart wear, convenient and practical; There is love around me and my warmth.

And the rehabilitation of chronic diseases (neck, shoulder, back pain, rheumatoid arthritis, degenerative diseases, etc.). ); Women's physiological health care needs (dysmenorrhea, gastrointestinal discomfort, postpartum rehabilitation, etc. ); Physical therapy needs of sedentary and sub-healthy people in the office (shoulder and neck, back physiotherapy, eye care, etc. ).
Application of Graphene Heating Film: Transparent Heating Film
Graphene has excellent conductivity and ultra-high transmittance, and can be used in transparent electrodes, solar cell electrodes, liquid crystal displays and other fields. At present, ITO and FTO (fluorine-doped tin oxide) are mainly used as electrodes for liquid crystal displays and solar cells. These materials are good electrode materials because they have good electrical conductivity and light transmittance. However, this method of using metal oxide coating has also begun to appear various problems, mainly in:
1. Indium available on the earth is limited, and it is estimated that it may be exhausted in 10 years, with high cost;
2. This kind of material is not stable in acidic or alkaline environment, and it is easy to cause the film to fall off, so its application range is limited;
3. Ions can easily diffuse into the polymer layer;
4. The light transmittance of this kind of materials is limited to the near infrared region, that is, when the light wave length is longer than 1200nm, the light transmittance decreases significantly, which leads to the inability to make full use of sunlight;
5. Current leakage is caused by structural defects in FTO.
Based on the above reasons, people began to look for a new type of electrode material, which requires high stability, high transmittance and good conductivity. At this time, the application of graphene heating film began to be widely concerned. The transmittance and conductivity of ideal single-layer graphene are about 98% and about100 Ω/sq, respectively, which is suitable for transparent conductive materials. Compared with the traditional indium tin oxide and fluorine-doped tin oxide electrodes, graphene films have higher mechanical strength, flexibility and better chemical stability.
The advantages of graphene heating film in physics, chemistry and machinery can make it a darling in many fields. Like the preparation of graphene, the application of graphene heating film is also a research hotspot at present. As one of the most practical applications of graphene, transparent conductive film is expected to become a widely used substitute for ITO, which can be used in touch panels, flexible liquid crystal panels, solar cells and organic EL (Electroluminescence) lighting. Due to the high carrier mobility and thin thickness of graphene, the application of graphene heating film and transparent conductive film is expected. Generally speaking, high transparency and high conductivity are contradictory. From this point of view, ITO is just on the edge of the trade-off relationship between transparency and conductivity (as shown below).
Theoretically, the application of graphene heating film is expected to avoid this trade-off and become an ideal transparent conductive film. Graphene's high carrier mobility makes it easy to transmit light in a wider wavelength range, but its conductivity is not affected. Therefore, graphene film is expected to become an epoch-making transparent conductive film. In addition, compared with ITO, which is not suitable for bending, graphene film also has the advantage of good flexibility.
Graphene is ultra-thin and highly transparent, which makes the conductive substrate with graphene as electrode have better light transmittance than other materials, and can replace transparent and conductive ITO electrode for organic solar cells. These thin films can also be used to replace silicon thin film transistors in display screens. Graphene can transport electrons dozens of times faster than silicon, so transistors made of graphene run faster and save electricity. In addition, touch panel products are constantly coming out. Moreover, the preparation method of large-size graphene is completely suitable for industrial production, and the cost is much lower than that of traditional methods.
