A high-voltage electrospinning method for liquid polymer materials

Abstract

The invention discloses a high-voltage electrostatic spinning method for liquid polymer materials, which belongs to the technical field of textile fibers. The method is to dissolve materials such as liquid polymer materials, polymer surfactants and curing agents into organic solvents, configure them as spinning precursors, and place the prepared spinning precursors in spinning devices for high-voltage electrospinning , and in the high-voltage electrospinning process, the spinning precursor liquid sprayed out from the spinning needle of the spinning device is heated by the curing heating device to evaporate the organic solvent and solidify the liquid polymer material to obtain a fiber film . The invention successfully prepares the liquid polymer material that cannot be spun into a fiber membrane in the prior art, realizes a technological breakthrough, and overcomes the technical problem that the liquid polymer material cannot be spun. The fiber membrane prepared by the invention has a porous structure, small specific mass and good 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, belonging to the technical field of textile fibers. Background technique [0002] When the epoxy value of epoxy resin is less than or equal to 12, it is solid, and when the epoxy value is greater than 12, it is liquid. In the existing spinning technology, only solid epoxy resin can be used for spinning, and liquid ring with epoxy value greater than 12. Oxygen resin 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. So far, no example of spinning liquid substances has been found. SUMMARY OF THE INVENTION [0003] The invention provides a spinning method using liquid polymer material combined with high-voltage electrostatic spinning technology. A kind of liquid polymer material is combined with electrospinning techn...
