The nano-superconducting composite material comprises the following raw materials of, by weight, 80-120 parts of graphene, 30-50 parts of yttrium powder, 30-50 parts of niobium powder, 20-30 parts of sodium fluoride, 10-20 parts of PPS resin, 3-5 parts of single-walled carbon nano tubes, 20-25 partsof superconducting carbon black, 5-10 parts of conductive metal mixtures, 5-10 parts of carbon nano tube dispersion solutions, 1-5 parts of rheological agents, and 3-5 parts of antioxidants. A quartzboat is put into a tubular furnace, in protection of mixed gas of 5-7% of hydrogen and 96-98% of nitrogen, the furnace is heated up to the temperature being 1050-1450 DEG C, heat preservation is conducted for 7-9 hours for a sintering reaction, then the furnace is quickly cooled to the room temperature, and thus the nano carbon conductive fiber yttrium-niobium-silver superconducting material is prepared. The nano-superconducting composite material is ingenious in design, reasonable in composition and proper in method, and the obtained superconducting composite material is good in physical property and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of nano superconducting composite materials, in particular to a nano superconducting composite material and a preparation method thereof. Background technique [0002] According to the structure and composition of materials, conductive polymer materials are divided into two categories: structural type and composite type. Structural conductive polymer materials, also known as intrinsic conductive polymer materials, are materials that have conductive functions after chemical or electrochemical doping of polymers with conjugated π bonds or partial π bonds. Structural conductive polymer materials have disadvantages such as refractory, insoluble, difficult to form, mostly toxic and corrosive substances, narrow range of conductivity, poor conductivity stability and high cost. Very restrictive. Composite conductive polymer material is a multi-phase composite system with conductive function by adding one or more c...
