Guidelines for the use of silicon carbide whiskers

1) Silicon carbide whiskers  should be pre-dispersed as much as possible before use. They should be mechanically and ultrasonically dispersed with water, ethanol, etc., and then mixed with the matrix material. 2) The amount of silicon carbide whiskers added to the material is not as high as possible, and there is usually an optimum value. Ordinary ceramics are generally added in an amount of 1-10%. The greater the true density of the matrix material, the lower the amount of silicon carbide whiskers added; the organic composite material is added in an amount of 0.5-3%. 3) When silicon carbide whiskers are mixed with ceramic materials, mechanical agitation or slurry wet ball milling is recommended to reduce the chance of silicon carbide whiskers breaking under high-intensity mixing conditions. 4) Low-viscosity silicon carbide whisker composite slurry, it is recommended to use rotary evaporation drying, or as large as possible to form a large-area thin layer of slurry to avoid the...

What is copper nanowire and what is its application

Transparent conductive films are an important part of many optoelectronic devices, such as flat panel displays, organic solar cells, organic light emitting diodes (OLEDs), smart windows, and the like. Indium tin oxide (ITO) has become the main material of transparent conductive films due to its high electrical conductivity and light transmittance. However, ITO also has some disadvantages, such as the rising price of raw material indium, which is expensive to prepare, and in addition, once the ITO material is bent, its electrical conductivity is greatly reduced. Therefore, it is extremely important to develop new materials that can replace ITO. Currently, transparent conductive materials that are expected to replace ITO are doped with ZnO, carbon nanotubes, graphene, metal lanthanum and metal nanowires. Among them, carbon nanotubes, graphene, and silver and copper have attracted much attention in terms of flexibility, stability, and electrical conductivity. Among these alternative mate...

Chinese companies have successfully produced metal nanomaterials below 10 nanometers

Through cooperation with domestic research institutes, Chinese companies have created a process oxidation method in the world after several years of trial and error and technological breakthroughs. They have taken the lead in the international production of metal nanomaterials below 10 nanometers, which has caused international industry. highly anticipated. The Chinese company independently researched and developed the photocatalytic net like 'fishing net' with graphene-doped metal nano-titanium dioxide material below 10 nanometers. It has been applied to the domestic black-smelting river water treatment this year. As we know, superparamagnetic nanomaterials below 10 nanometers are an advanced material that is urgently needed in modern medicine, pharmacy, biotechnology and military equipment. However, to achieve mass production of metal nanomaterials below 10 nanometers, the technical difficulty is very high. In the past 10 years, although domestic research institutions have...

Nanotechnology is also a "double-edged sword"

In our daily lives, nanotechnology will bring unexpected surprises to people. With nanometer (nm) coating, the refrigerator can be made into antibacterial, can be made into sterile tableware, can be made into self-cleaning glass and tiles without scrubbing. Using nanotechnology to make a micro drug delivery device, it can accurately reach the lesion site and reduce the adverse reactions of the drug. Nanomaterials  are made up of ultra-fine particles of less than 100 nanometers (nm) and are unique in size and function beyond imagination. Nanotechnology is also a "double-edged sword". While bringing convenience to life, it also has potential risks. Environmental ecological risk of nanomaterials Researchers have used nematode model organisms to find that nanomaterials that enter the environment can be transported along the food chain, accumulating in high-level organisms and exhibiting toxic effects. It not only causes damage to the parents, but also damages future generatio...

Nano-pigment on plastic spray becomes "metal"

Rose gold, champagne gold, green gilt, snow silver... These beautiful and shiny "metals" are actually plastic products! The ultra-dispersive color aluminum pigment products developed by the most advanced "nano-micro coating technology" were unveiled at the high-tech fair yesterday. The core technology that makes plastics look beautiful in metallic texture is “nano-micro coating technology”. In layman's terms, it is to put a layer of "clothes" on these pigments so that they can swim in the water like swimming in the water, and the colors are very scattered. The beautiful colors can be achieved. Metal plating is even the same as high-gloss paint, and the variety of aluminum pigments is very rich, including rose gold, champagne gold, bright silver, bright gold, green gold, red gold, blue gold, black gold, bronze, ancient silver and so on. In addition, another highlight of the “paint-free color aluminum pigment” is the world's first “paint-free” t...
