l Conductive polymer materials
| Conductive polymer materials are a type of polymer materials whose electrical conductivity is close to that of metals or semiconductors. Their unique electromagnetic properties, mechanical plasticity, corrosion resistance, and low cost have attracted widespread attention. They are widely used in various fields such as electronic devices, electromagnetic shielding, metal anticorrosion, polymer batteries, conductive rubber, transparent conductive films, medicine, biosensors, electrochromic devices, and information storage materials. |  |
Our company has developed a series of composite conductive and semiconductor polymer materials.。

l Magnetic polymer materials
| Ferrite magnetic materials are generally made through secondary sintering. The sintering temperature is as high as about 1200℃. They are hard and brittle, with large deformation. It is difficult to make products with complex shapes and high - dimensional accuracy, and the yield rate is relatively low. Composite magnetic polymer materials have emerged as a new force. They can be used to prepare small - sized and special - shaped permanent magnets, and are widely applied in fields such as intelligent control, wave - absorbing materials, electronics and electrical appliances, biomedicine, and office supplies. Compared with sintered magnets, they have advantages such as low energy consumption, low density, stable magnetism, easy processing and molding without shape restrictions, no need for post - processing, high - dimensional accuracy, good flexibility, high output, and low cost. |  |
Our company has developed a series of composite magnetic polymer materials.
