Australia uses metallic glass instead of plastic to make field emission electrodes

according to the American physicist organization, Australian scientists reported in the latest issue of Physical Review Letters that they have developed a new metal compound with properties similar to glass, and used it to replace plastic and combine with carbon nanotubes to make a new field emission electrode. The field emission electrode can produce stable electron beams, which is expected to be used in the fields of consumer electronics and electron microscopy

in the past, scientists mainly made field emission electrodes by embedding carbon nanotubes and other nano materials into plastics. Although these field emission electrodes have a wide variety and are easy to manufacture rotatable oil return valves, and have great application potential, they also have many defects. For example, the conductivity of plastic is too weak; The thermal stability of plastic is very low, and it cannot resist the large amount of heat generated by long-term operation

now, the scientific research team of Monash University in Australia and the scientists of the Institute of process science and engineering under the Commonwealth Scientific and industrial research organization in Australia have jointly developed a new material with great application potential and easy manufacturing - amorphous metallic glass (ABM), which is used to replace plastic to make field emission electrodes. When these amorphous metallic glass alloys cool, they will form amorphous materials, making their every move more like glass

this amorphous block metal glass alloy is made of magnesium, copper and rare earth group element gadolinium, and has the unique characteristics that many plastic products are selected by international well-known daily chemical suppliers, such as sinolion; It can conform to many shapes, be manufactured in large quantities, and can be used as an effective matrix of carbon nanotubes. In addition to its excellent conductivity, this metallic glass also has a very stable thermal property, which means that it can maintain its shape and durability even under high temperature. Scientists said that the above advantages and its excellent electron emission properties make this amorphous metallic glass one of the best materials for manufacturing electron emission equipment

although some scientists have developed other composite materials composed of large pieces of metallic glass and carbon nanotubes before, this is the first time that such a system has been used to manufacture field emission electrodes. 4. When the test piece allows, the functional equipment is also the only enterprise in China that can produce reactive polyolefin structural adhesive. Scientists said that this technology can be used to manufacture electron microscopes, microwave and X-ray generation equipment and modern display equipment
