Nanotechnologyis a high-tech that emerged in the late 1980s. Its basic meaning is to study the composition of matter in the nanometer size range and to create new substances by directly manipulating and arranging atoms and molecules. The emergence of nanotechnology marks that human cognition has expanded to the atomic and molecular levels, marking the new time of human science and technology--the advent of the nanotechnology era.
Nanotechnology is a science and technology based on many modern advanced science and technology. It is a combination of modern science (quantum mechanics, molecular biology) and modern technology (microelectronics, computer technology, high-resolution microscopy and thermal analysis). Product. Nanotechnology has penetrated into various fields of modern science and technology, and has formed many new researches related to nanotechnology, such as nanophysics, nanochemistry, nanomaterials, nanobiology，nanoelectronics, nanofabrication, and nanomechanics. All of these make up nanotechnology.
In the middle of the 18th century, the first industrial revolution represented by steam engines was the symbol of the application of millimeter technology, which enabled mankind to enter the industrial era of replacing manpower with machinery. In the 20th century, the second industrial revolution represented by microelectronics was the hallmark of micron technology applications, enabling humans to enter a new time of computer and communication networks. It is foreseeable that the emerging science and technology represented by nanotechnology will bring a third industrial revolution to mankind in the 21st century.
While nanotechnology creates many new substances and materials for human beings, it will bring us profound changes in cognitive concepts. Taking electronic technology as an example, in today's micron era, microelectronics has played a decisive role in human development and life; in the era of nanotechnology, nanoelectronics is the future because of the reduction in the positivity of electronic devices to nanometers and even single molecules. The role of electronic technology development will be incalculable.
Nanomaterials
Nanomaterials are an important foundation for the development of nanotechnology and the most important research object of nanotechnology. The basic units that make up nanomaterials can be divided into three categories in terms of dimensions:
Zero dimension. Refers to the three-dimensional dimensions in space are in the nanometer scale. Such as nanoscale particles, clusters, etc.
One-dimensional. Refers to two dimensions in space at the nanometer scale, such as nanowires, nanorods, nanotubes, etc.
Two-dimensional. It means that one dimension is in the nanometer scale in three-dimensional space, such as ultra-thin film, multilayer film, superlattice and so on.
Conclusion
Nanotechnology, with its new understanding of the material field, is undoubtedly setting off a technological revolution. Nanotechnology has provided us with initial demonstrations in new materials, new energy, computer technology, biomedical and aerospace applications. At the same time, nanotechnology is not isolated. It involves many disciplines such as quantum mechanics, materials science, colloidal chemistry, physical chemistry, polymer chemistry, biochemistry, condensed matter physics and microelectronics technology. Cross-infiltration of disciplines can better help us understand nanoscience and master nanotechnology.
