▎ 摘　　要

NOVELTY - Molybdenum disulfide and graphite oxide are dispersed in water, ultrasonically processed, and sodium deoxycholate is added to obtained molybdenum disulfide-graphene oxide mixed dispersion and stirred to obtain sodium deoxycholate/molybdenum disulfide-graphene oxide gel. Obtained gel is squeeze-dried and washed to obtain molybdenum disulfide-graphene oxide fibers. Hydroiodic acid is added to resultant mixture, reacted, washed and dried to obtain doped molybdenum disulfide graphene fibers. USE - Manufacture of doped molybdenum disulfide graphene fibers used for energy memory device, photovoltaic device and sensor device. ADVANTAGE - The method efficiently provides doped molybdenum disulfide graphene fibers having high electroconductivity and flexibility, by simple method. DETAILED DESCRIPTION - Molybdenum disulfide and graphite oxide are dispersed in water, and ultrasonically processed to obtain molybdenum disulfide-graphene oxide mixed dispersion. Sodium deoxycholate is added to the resultant mixture and stirred to obtain sodium deoxycholate/molybdenum disulfide-graphene oxide gel. The weight ratio of molybdenum disulfide, graphite oxide, sodium deoxycholate and water is 1-5:5-15:10-30:100-500. The obtained gel is squeeze-dried using a syringe, washed using absolute ethanol, and then with aspirated ethanol. Anhydrous ethanol is then evaporated from the resultant mixture to obtain molybdenum disulfide-graphene oxide fibers. Hydroiodic acid is added to the resultant mixture, reacted for 2-8 hours, washed, and dried to obtain doped molybdenum disulfide graphene fibers.
