Embodiment 1

[0028] Put the thermoplastic polyurethane fiber into pyrrole solvent (100%), swell for 0.1h, take it out and put it in 1mmol / L ammonium persulfate hydrochloric acid solution, after reacting for 1h, take out the polyurethane fiber and clean it with deionized water, and put it in a fume hood Air dry naturally. After the polyurethane deswells, it can induce the surface polypyrrole film to form two-dimensional wrinkles, and the wrinkle wavelength is 0.2 μm.

Embodiment 2

[0030] Put the thermoplastic polyurethane film into pyrrole solvent (100%), swell for 0.1h, take it out and put it in 1mmol / L ammonium persulfate hydrochloric acid solution, after reacting for 1h, take out the polyurethane film and clean it with deionized water, and put it in a fume hood Air dry naturally. After the polyurethane deswells, it can induce the surface polypyrrole film to form two-dimensional wrinkles, and the wrinkle wavelength is 0.3 μm.

Embodiment 3

[0032] Put the thermoplastic polyurethane fiber in pyrrole solvent (100%), swell for 120h, take it out and place it in 100mmol / L ammonium persulfate hydrochloric acid solution, after reacting for 0.01h, take out the polyurethane fiber and clean it with deionized water, and put it in a fume hood Air dry naturally. After the polyurethane deswells, it can induce the surface polypyrrole film to form two-dimensional wrinkles, and the wrinkle wavelength is 15 μm.

Abstract

The invention discloses a preparation method of polypyrrole wrinkles on the surface of a polymer elastomer. The preparation method comprises the steps: (1) putting the polymer elastic matrix into a pure solvent with pyrrole or a solvent co-dissolved with pyrrole, and swelling; (2) putting the obtained swelling polymer elastic matrix into an acidic aqueous solution of an oxidant, and carrying out areaction; and (3) completely deswelling the obtained polymer elastic matrix. The preparation method is simple and low in cost, and the prepared polypyrrole wrinkles can significantly change the roughness and other properties of the surface of the polymer matrix and have important application prospects in the fields of energy conversion, energy storage, sensors and the like.

Description

technical field [0001] The invention relates to the field of flexible functional materials, in particular to a method for preparing polypyrrole wrinkles on a polymer elastic surface. Background technique [0002] High-performance functional materials are the core of research in the field of new materials in recent years. The development of emerging industries requires a forward-looking layout of research and development of cutting-edge new materials, and the development of functional materials such as smart materials and bionic materials. The properties of materials are not only determined by their intrinsic properties, but also their compositional structure or form is also one of the important influencing factors. Generally speaking, it is difficult to change the intrinsic properties of materials, so researchers focus on the construction of unique micro-nano structures to endow materials with new functional applications. [0003] Wrinkles are structures formed by rigid mat...
