  • Patent number: 9171656
    Abstract: A cellulose material contains cellulose fibers having an impregnation. Accordingly, the impregnation is made of nanoparticles, in particular BNNT, containing a shell of polymers, in particular PEDOT:PSS. The impregnation forms a type of network that can reduce the specific resistance of the cellulose material due to the electrical conductivity of the network. The cellulose material can thereby be advantageously adapted to corresponding applications with respect to the electrical properties thereof. The cellulose material can thus also be used to electrically insulate transformers, wherein the cellulose material is thereby saturated with transformer oil and an adaptation of the specific resistance of the cellulose material to the specific resistance of the oil leads to improved dielectric strength of the transformer insulation. A method for producing the cellulose material described above contains a suitable impregnation step for the cellulose material.
