Abstract

The invention discloses a high-voltage electrostatic spinning method for a liquid polymer material, and belongs to the technical field of textile fibers. The method comprises the steps: materials suchas the liquid polymer material, a polymer surfactant and a curing agent are dissolved into an organic solvent to prepare a spinning precursor solution, and the prepared spinning precursor solution isput into a spinning device for high-voltage electrostatic spinning, in the high-voltage electrostatic spinning process, the spinning precursor solution sprayed out of a spinning needle of the spinning device is subjected to organic solvent evaporation and liquid polymer material curing under the heating effect of the solidification heating device, and a fiber membrane is obtained. According to the high-voltage electrostatic spinning method, the liquid polymer material which cannot be spun in the prior art is successfully prepared to form the fiber membrane, so that the technical breakthroughis realized, and the technical problem that the liquid polymer material cannot be spun is solved; and the prepared fiber membrane has a porous structure, is small in specific mass and good in heat insulation performance, and can be applied to the fields of flexible electronic devices, sensors and the like.

Description

technical field [0001] The invention relates to a high-voltage electrostatic spinning method of liquid polymer materials, which belongs to the technical field of textile fibers. Background technique [0002] The epoxy resin is solid when the epoxy value is less than or equal to 12, and is liquid when the epoxy value is greater than 12. In the existing spinning technology, only solid epoxy resin can be used for spinning, and the liquid ring with an epoxy value greater than 12 Oxygen resins cannot be spun. In addition, liquid phenolic resin, liquid silicone resin and liquid silicone rubber, the three liquid polymer materials, cannot be spun because they are all in liquid state, and no examples of liquid materials for spinning have been found so far. Contents of the invention [0003] The invention provides a spinning method using liquid polymer materials combined with high-voltage electrospinning technology. The method uses liquid epoxy resin (epoxy value greater than 12), ...
