Description
Technical Field
The invention belongs to the technical field of nano materials, and particularly relates to a PS (polystyrene) pellet layer number detection device.
Background
The nano material is a material with a brand new structure developed in the middle of the 80 s, and is a special particle with the size in the transition area between an atomic cluster and a macroscopic object. The definition as a material limits the size of the nanoparticles to the range of 1-100 nm. When the size of the particles is in the nanometer order, the nanoparticles have the following four effects: small size effect, surface effect, quantum size effect, macroscopic quantum tunneling effect. These four effects are the fundamental characteristics of nanoparticles, which make nanomaterials exhibit a wide variety of peculiar physical and chemical properties. For example: the metal is a conductor, but the nano metal particles can present electrical insulation at low temperature due to quantum size effect; ferromagnetic substances enter a nano-scale (5nm) and show extremely strong paramagnetic effect because a multi-domain is changed into a single domain; the chemically inert metal platinum becomes a catalyst with excellent activity after being made into nano particles (platinum black). The exotic characteristics of the nano material completely different from bulk phase materials show attractive application prospects in the fields of ceramics, microelectronics, bioengineering, photoelectricity, chemical industry, medicine and the like.
For example: the polystyrene microsphere has the characteristics of large specific surface area, strong adsorbability, large agglutination, strong surface reaction capability and the like, has wide application prospect, and the polymer microsphere with uniform micron-sized particle size as a functional polymer material has wide application in the fields of analytical chemistry, biochemistry, immunology, standard measurement and certain high and new technology, so that the research on the material is more and more focused. The method comprises the steps of assembling polystyrene microspheres through solvent volatilization and a template method to obtain a PS sphere array, forming an ordered micro-nano composite array by assisting a physical metal plating technology, and constructing a new generation of SERS detection substrate.
In practical applications, single-layer PS beads are used more often, and therefore, in the manufacturing process, it is necessary to detect whether the manufactured PS beads are single-layer.
