Abstract

The invention relates to polymer-based metal phthalocyanine / graphite nanosheet composite and a preparation method thereof, and belongs to the technical field of polymer-based nanocomposite. The polymer-based metal phthalocyanine / graphite nanosheet composite is composed of, by weight percent, 5-20% of graphite nanosheets and larger than 0% to equal to 30% of metal phthalocyanines, and the balance of polymer matrix. The preparation method includes using the metal phthalocyanines to pretreat the graphite nanosheets, and compositing the graphite nanosheets with polyvinylidene fluoride or polyether sulfone. By the method, the graphite nanosheets are evenly dispersed in the matrix, the graphite nanosheets are prevented from directly contacting with the polymer, dielectric constant of the composite can be increased effectively, and dielectric loss of the composite can also be controlled.

Description

technical field [0001] The invention belongs to the technical field of polymer-based nanocomposite materials and their preparation, in particular to polymer / nano-graphite microchip composite materials with high dielectric properties and a preparation method thereof. Background technique [0002] The progress of integrated circuit (Integral Circuit, IC) technology determines the development of microelectronics industry, and the development of electronic packaging technology (Electronic Packaging) determines the progress of IC technology. The development of electronic packaging technology can meet the needs of IC technology in terms of interconnection technology. The development of electronic packaging technology can be divided into three generations. The first generation uses discrete components for packaging, and it needs to occupy about 80% of the circuit board area for the IC to get enough support. The second generation uses chip-scale packaging and multi-chip modules to...
