Method for manufacturing a polymer composite material and method for manufacturing a capacitor package structure using the polymer composite material

A method for manufacturing a polymer composite material, comprising:

• mixing a carbon nanomaterial with polystyrene sulfonate to form a carbon nanomaterial modified by polystyrene sulfonate;
• adding 3,4-ethylenedioxythiophene into a solution comprising the carbon nanomaterial modified by polystyrene sulfonate;
• and
• initiating a polymerization reaction to allow a reaction between 3,4-ethylenedioxythiophene and the carbon nanomaterial modified by polystyrene sulfonate in the solution for forming a product stream comprising the polymer composite material, the polymer composite material comprising a poly(3,4-ethylenedioxythiophene) unit, a polystyrene sulfonate unit and the carbon nanomaterial;
• wherein the polystyrene sulfonate unit is connected between the poly(3,4-ethylenedioxythiophene) unit and the carbon nanomaterial, and the polystyrene sulfonate unit is bonded to the poly(3,4-ethylenedioxythiophene) unit through a polymerization process, the content of the nanomaterial ranging from 0.01-1.5 wt. % based on the weight of the polymer composite material.
