Technology, What is a nanocomposite?
  Nanocomposite is the composite which unites more than two nanoparticles and has more effective function on the chemical and physical side than just collecting them. Nano is the scale of 10^-9 meter. We use 10nm under particles for nanocomposite, which displays 1/one hundred thousand times of hair thickness by numerical value. It has excellent performance until current micrometer level material doesnĄ¯t have.

  The nanocomposite has been reported much more excellent than former time's general meterial performance. In case of the nanocomposite for high-strength plastics that unite clay nanoparticles with basic polymer,
it has been reported to have elasticity and tensile 2 times over more than general one by Toyota consocium.

  Lately, possibility of highest-strength plastics united with carbon nanotube (CNT) development is being expected. Additionally, conductive plastic, intelligent ceramics is being studied. Our antimicrobial polymer is just entering into commercial step.

  It is needed the technology that unite different materials on a nano scale controlling them to keep its own molecule or several nano size state to make the composite with nanoparticle. Usually nanoparticles under 10nm have Van der Waals forces with strong surface energy, and it is more difficult to prevent from coagulation especially in the condition of high temperature and pressure for plastic engineering. Therefore the chemical and physical process is essential to arrange them regularly and keep its own size. It is nano chemistry engineering.

  Nanocomposite technology which started 10 years ago is making new business field. It is evaluated as 'Flower' which is just entering into industrialization step among many nanotechnologies because it can be expected various practical uses for new material. Technical gap between leading companies and newly rising companies is not so big, and competition will be very severe in this field. SILVIX Co., Ltd is stammering this pilot business prior to any other company with frontier experience and effort on environment and energy field.

  The several tries to make a compound of nanoparticle and polymer were performed in last decades. KP 20-0397627, KP 10-0535916, KP 10-0599532, KP 10-0456341, and other Korea patents were reported to make a compound with various methods. Researchers are making nano particle or colloid and used then to the process of making master batch. However they just focused on compounds, not on the dispersing method in the polymers. Traditional master batch method will give nanoparticles aggregates each other and partially suspended. There is no concern of dispersing nanoparticles in the polymers. This show if someone develops the new technique to disperse nanomaterial into the polymers, which will lead a new basic technique in the nanomaterial fields.

  Traditional method is just the physical blending, stepwise particle growth is the physic-chemical method to make complex nanomaterial. This method based on the properties of nanoparticles, that nanoparticles cannot be blended easily due to their active chemical characteristics. The TOP-DOWN method cannot control the aggregation of nano in secondary or tertiary processing so that mass production could not be possible. Through this technique nanocomposite can be treated as new materials and SILVIX is the first company treating nanocomposites to be a new material.

Stepwise particle growth method is very useful to develop another new materials using nancomposite. Antibacterial plastic, recently SILVIX has launched, would be the first model in this case. This plastic was developed combining both of nanoparticle and polymer in physicochemical way. Indoor air purification plastic, fiber, textiles are other similar examples that nanocomposite catalyst and polymer were compounded very well. In other examples, SILVIX has planned to launch warming nanoparticle-polymer materials, conductive nanoparticle-polymer materials, flexible conductive plastics, ultra high strengthen plastics using the same method as mentioned.

Stepwise particle growth method was patented in Korea, and also in patent-pending in US, EU, Japan, China
