What Is a Nanocomposite?

Nanocomposites are based on resin, rubber, ceramics, and metals as continuous phases, and nanometer-sized metals, semiconductors, rigid particles and other inorganic particles, fibers, and carbon nanotubes are used as dispersed phases. Methods The modifier was uniformly dispersed in the matrix material to form a composite system containing nano-sized materials in one phase. This system material is called nano-composite material.

Nano composite material background

Composite materials are widely used in aerospace, defense, transportation, sports and other fields due to their excellent comprehensive properties, especially the designability of their properties. Nanocomposites are the most attractive part of them, and they are developing rapidly. The development strategies of new materials in developed countries all place the development of nanocomposites in an important position. The research direction mainly includes nano-polymer-based composite materials, carbon nanotube functional composite materials, and nano tungsten copper composite materials.

In terms of nano-polymer-based composites, co-rotating twin-screw extrusion was used to disperse the nano-powders, and the dispersion level reached nano-level, and nano-composites with properties meeting design requirements were obtained. Among the nano-montmorillonite / PA6 composites we prepared, the interlayer spacing of the nano-montmorillonite is 1.96nm, which is at the leading level of similar materials in China (1.5 ~ 1.7nm in the Chinese Academy of Sciences). Completely exfoliated into nanoparticles with a thickness of 1 ~ 1.5nm, the composite material has excellent temperature resistance, barrier properties, and water absorption resistance. This material has achieved industrialization; the nano-TiO2 / polypropylene composite material under development has excellent Antibacterial effect, nano-TiO2 powder dispersed in polypropylene below 60nm, this technology is applying for an invention patent.

Because the molding process of nano-polymer composites is different from ordinary polymers, this direction is also actively developing new molding methods to promote the industrialization of nano-composites.

Carbon nanotubes are a new type of carbon cluster fiber material discovered in the early 1990s. They have many particularly excellent properties.

Our research achievements in carbon nanotubes include:

1) The technology of large-scale production of multi-walled carbon nanotubes, the quality of the produced carbon nanotubes is at the world advanced level, and the production cost is also very low, creating conditions for the industrial application of carbon nanotubes.

2) Developed a technology for manufacturing electric double layer capacitors with carbon nanotubes as electrode material.

3) Developed a technology for manufacturing oriented carbon nanotube films with a soft substrate.

Tungsten copper composite materials have good electrical and thermal conductivity and low thermal expansion coefficient and are widely used as electrical contact materials, electronic packaging and heat sink materials. Nano-tungsten-copper composites prepared with nano-powders have very excellent physical and mechanical properties. We have successfully prepared nano-tungsten-copper composite powders and nano-tungsten-copper composite powders by adopting internationally advanced metal composite salt solution atomization drying reduction technology. At present, it is stepping up its industrial application research.
