Abstract

The invention relates to a polydopamine (PDA) modified fluororesin mixture, a prepreg prepared from the polydopamine modified fluororesin mixture and a copper-clad plate. The surface of an inorganic filler is modified with amino, and then PDA is connected to the surface of the inorganic filler through chemical bonds through a reaction of the amino and dopamine. By modifying glass fiber cloth withthe PDA, on one hand, the compatibility between the inorganic filler and fluororesin is improved, and the dispersity of the inorganic filler in the fluororesin matrix is promoted; on the other hand, the interaction between the inorganic filler, the fluororesin, the glass fiber cloth and copper foil is enhanced. Furthermore, the high-frequency copper-clad plate prepared from the prepreg, a film andcopper foil is good in thermal-mechanical property, dielectric property, combination property stability and uniformity, especially, the copper foil peel strength is very high, and the requirements ofthe high-frequency communication field for various combination properties of a substrate material can be met.
