Reduced and Surface‐Modified Graphene Oxide with Nonlinear Resistivity

Field‐grading materials (FGMs) are used to reduce the probability for electrical breakdowns in critical regions of electrical components and are therefore of great importance. Usually, FGMs are heavily filled (40 vol.%) with semi‐conducting or conducting particles. Here, polymer‐grafted reduced grap...

Zusammenfassung:	Field‐grading materials (FGMs) are used to reduce the probability for electrical breakdowns in critical regions of electrical components and are therefore of great importance. Usually, FGMs are heavily filled (40 vol.%) with semi‐conducting or conducting particles. Here, polymer‐grafted reduced graphene oxide (rGO) is used as a filler to accomplish percolated networks at very low filling ratios (
