Problems solved by technology

However, fluorine-containing resins generally cannot chemically react with coupling agents, so it is difficult to form chemical bonds between the fluorine-containing resin matrix and inorganic fillers, glass fiber cloth or copper foil
In addition, the interaction between the common alkane chain at one end of the commonly used coupling agent and the fluorine-containing polymer chain is also very weak.

Abstract

The invention relates to a polyphenol-modified fluorine-containing resin mixture and a prepreg and a copper-clad laminate prepared therefrom. The present invention modifies the surface of the inorganic filler and the glass fiber cloth with polyphenol, so as to promote the dispersion of the inorganic filler in the fluorine-containing resin matrix, improve the compatibility between the inorganic filler, the glass fiber cloth and the fluorine-containing resin, and further Enhance the interaction between inorganic filler, fluorine-containing resin, glass fiber cloth and copper foil. Further, the high-frequency copper-clad laminate made of the prepreg, film and copper foil has good thermal-mechanical properties, excellent dielectric properties, good overall performance stability, and good uniformity, especially the peel strength of the copper foil is very high, It can meet the comprehensive performance requirements of substrate materials in the high-frequency communication field.
