Description

technical field [0001] The patent of the present invention relates to the field of electrospinning fibers, in particular to a graphene oxide / modified phenolic resin (UM-PF) electrospinning fiber. Background technique [0002] Electrospinning technology has been reported in several patents and laboratory studies. In the electrospinning process, an electric field is formed on the liquid surface first, and when the electric field force acts on the liquid surface, a charged liquid jet will be generated on the liquid surface. The jet of liquid is drawn by the oppositely charged substance with the right electrical potential. As the liquid jet is stretched, it is dried and solidified to form fibers. The stretched liquid jet can be solidified and dried by physical solidification such as cooling of the liquid, evaporation of solvents, etc., or by chemical solidification. The resulting fibers are collected by a suitably placed and reversely charged receiver device, and the fibers c...
