Problems solved by technology

Among them, micron particles can improve the mechanical and thermal stability properties of epoxy resin, but will reduce the insulating properties of epoxy resin
The introduction of inorganic oxide nanoparticles can improve the breakdown strength of epoxy resin and reduce the dielectric constant and loss. However, due to the large specific surface area of ​​nanoparticles, nanoparticles will cause a sharp increase in the viscosity of the system and affect the preparation of composite materials. process, and the impurity ions and hydroxyl groups contained on the surface of nanoparticles promote the conduction of carriers in the system and reduce the volume resistivity of the system
