Nanomaterials have completely changed our life and triggered the development of science and technology. Plastic is the product of industrial civilization and the progress of nanomaterials research. The synthesis of plastic greatly improves the convenience of our life, but when dealing with plastic gradually becomes a difficult problem; Research into biodegradable materials to replace plastic is rapidly on the agenda and has yielded results, but is still limited by high costs. In this topic, we can understand the characteristics and applications of various nanomaterials.
With the development of science and technology, nanotechnology is becoming more and more mature. Nanotechnology plays an important role in many fields. For example, the application of nano-science and technology can lead to the revolution of optoelectronics, microelectronics, environmental protection and other fields, and promote the take-off of social economy. Nano-electronics, nano-optoelectronics and nano-photonics will become the key technologies of the information age in the 21st century. Nano semiconductor photoelectronic materials have a very broad development prospect because they contain many new physical information and can be used for unique functions. It is a new star of semiconductor photoelectronic materials. Its appearance means that semiconductor photoelectronic materials develop towards the direction of low dimension.
