Graphene, Extraordinary Thin Magical And More
Graphene is a kind of single-layer lamellar structure composed of carbon atoms. It is the thinnest and most powerful two-dimensional material discovered by human beings so far because of its strong hardness, extraordinary conductivity and excellent The translucency, known as "changing the material of the 21st century." However, due to the high cost of preparation, the industrial application of graphene has been delayed. Polish scientists recently invented the graphene preparation method, so that the industrial production of graphene possible.
Since the two scientists in the UK succeeded in separating the magic nanomaterials of graphene in 2004, low-cost, high-quality and large-scale graphene preparation methods have become the targets of the global industry and researchers. At present, the common methods of preparation of graphene are physical stripping method and chemical deposition method. The former is the most important means for obtaining high purity graphene in the laboratory. The disadvantage is that the graphene is small in size and expensive. Although the chemical method can produce large area Graphene, but the purity and quality are low.
In recent years, the scientific research on graphene is progressing rapidly, and its industrial application is also on the arrow. It is predicted that once the production of graphene, will be in the touch screen, energy storage batteries, sensors, semiconductors, aerospace, military, biomedical and other fields ambitious, become the next trillion industry. Huge market prospects, making the world set off a gravel research and development and investment boom. According to incomplete statistics, in 2012 around the world a total of 3520 research on graphene patent applications, but the vast majority of them still not out of the laboratory. Therefore, the new graphene preparation technology can ultimately benefit mankind, ultimately depends on its ability to successfully put into industrial production.
