Abstract

The invention discloses a method for preparing fibers in a linear structure through pickering emulsion electrospinning. The method comprises the steps of preparing pickering emulsion by using a sodium alginate derivative, nano-silica and cypermethrin, then preparing spinning emulsion dispersion liquid, carrying out high-voltage electrostatic spinning on the emulsion dispersion liquid, and collecting fibers with a slab or a roller, thus obtaining the micro-nano fibers in a linear structure. Compared with the prior art, the method has the beneficial effects that different morphologies of fibers in a linear structure are prepared by changing the ratio and spinning working parameters of the pickering emulsion dispersion liquid; by preparing the linear fibers by adopting the mode of pickering emulsion electrospinning, the preparation method is accessible in raw materials, simple in process and mild in conditions, is environment-friendly and safe, easily achieves mass production and has popularization and application values.

Description

technical field

[0001] The invention relates to a method for preparing biopolymer materials, in particular to a method for preparing linear structural fibers by pickering emulsion electrospinning. Background technique

[0002] Sodium alginate is a natural polysaccharide polymer extracted from kelp or seaweed. It is a renewable marine resource. Sodium alginate has the advantages of non-toxicity, low cost, wide range of sources and biodegradability. Pickering emulsion is a thermodynamically stable and kinetically unstable system in which solid particles are used as emulsifiers instead of surfactants in traditional emulsions. The wettability of solid particles is one of the main factors affecting the stability of solid emulsions. The solid particles are activated by sodium alginate derivatives to change the wettability and form a stable pickering emulsion.

[0003] Due to their high specific surface area, micro-nanofibers have high application value in the fields of biomedici...
