Varistor effect in highly heterogeneous polymer–ZnO systems

详细

Composite varistors based on polar and nonpolar polymers (the matrix) and inorganic phase (dispersant) ZnO are studied. It is shown that composite varistors with a high breakdown electric field and a high nonlinearity can be developed by varying the physical structure of the polymer–ZnO heterogeneous structure. Nonpolar polyethylene and nonpolar polyvinylidene fluoride are chosen as the polymeric matrix.
