ELECTRICALLY INSULATING NANOCOMPOSITE HAVING SEMICONDUCTIVE OR NON-CONDUCTIVE NANOPARTICLES, USE OF SAID NANOCOMPOSITE, AND METHOD FOR PRODUCING SAME

摘要

The invention relates to a cellulose material comprising cellulose fibers (12) having an impregnation. According to the invention, said impregnation is made of nanoparticles, in particular BNNT (11), comprising a shell of polymers (13), in particular PEDOT:PSS. The impregnation forms a type of network (14) that can reduce the specific resistance of the cellulose material due to the electrical conductivity of said 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. The invention further relates to a method for producing the cellulose material described above, comprising a suitable impregnation step for the cellulose material.
