PROCESS OR METHOD FOR INSERTING OR SPREADING QUARTZ INSIDE A SUBSTRATE

摘要

A method for inserting or dispersing quartz inside a substrate (10) containing polymers polarisable by an electromagnetic field having electric resistivity, from insulator to conductor and vice versa, modifiable by said field, is described. The method involves dispersing in the substrate particles (P) comprising, in a sandwich structure, two conductor layers (E) and one quartz layer (Qinv) in the middle.
