preparation example Construction

[0029] refer to Figure 1-Figure 3 , the preparation method of the polyaniline needle pad array film with electric field response to hydrophilic and hydrophobic changes of the present invention comprises the following preparation steps:

[0030] 1) Preparation of polystyrene ordered pin-cushion membrane template

[0031] At room temperature, 30 mL of the chloroform solution of polystyrene and polydodecyl acrylamide-6-aminocaproic acid was placed in a petri dish. The concentration of polystyrene in the mixed solution was controlled at 1-5 g / L, and the poly The concentration of dialkylacrylamide-6-aminocaproic acid is about 1 / 10 of that of polystyrene, and a humid air stream with a relative humidity in the range of 30-80% is continuously blown above the mixed solution at a speed of 4L / min. A layer of opaque cellular ordered porous membrane is formed on the surface rapidly. After 15-20 minutes, after the solvent is completely volatilized, the surface of the cellular ordered poro...

Embodiment 1

[0038] Preparation of polyurethane (PU) needle pad array matrix: The pores of the polystyrene (PS) ordered needle pad film were filled with 20 g / L water-soluble polymer polyvinyl alcohol (PVA) aqueous solution, and the film was placed in 50 mL after the water was completely evaporated. In the chloroform solution, polystyrene (PS) was dissolved to obtain a chloroform-insoluble polyvinyl alcohol (PVA) reverse pin pad array film. 35g / L of polyurethane (PU)-dissolved tetrahydrofuran (THF) solution was filled into the polyvinyl alcohol (PVA) reverse pin pad array film, and after the chloroform organic solvent was completely evaporated, the film was immersed in deionized water, and polyvinyl alcohol (PVA) was used. PVA) was dissolved to obtain a water-insoluble polyurethane (PU) pin pad array film substrate.

Embodiment 2

[0040] Preparation of polyurethane (PU) needle pad array matrix: The pores of the polystyrene (PS) ordered needle pad film were filled with 20 g / L water-soluble polymer polyvinylpyrrolidone (PVP) aqueous solution, and the film was placed in 50 mL after the water was completely evaporated. In the acetone solution, polystyrene (PS) was dissolved to obtain an acetone-insoluble polyvinylpyrrolidone (PVP) reverse pin pad array film. 35 g / L of polyurethane (PU)-dissolved tetrahydrofuran (THF) solution was filled into the polyvinyl alcohol (PVA) reverse needle pad array film, and the film was immersed in deionized water after the acetone organic solvent was completely evaporated, and polyvinylpyrrolidone ( PVP) was dissolved to obtain a water-insoluble polyurethane (PU) pin pad array film substrate.

Abstract

The invention provides a polyaniline pincushion array film having electric field responding hydrophilic / hydrophobic change and a preparation method thereof. The preparation method is characterized by comprising the preparation of a polystyrene ordered pincushion film template, the preparation of a polyurethane pincushion array matrix and the preparation of the polyaniline pincushion array film. The preparation method is scientific and reasonable, and low in energy consumption and cost. Micron porous edge pinpoint projections are formed on the surface of the prepared polyaniline pincushion array film; the surface of the matrix material is rough and has extremely high adhesion, and therefore, the coating quantity of the polyaniline on the surface of the matrix is increased, the electrical conductivity and the electrostriction are enhanced, and dimensional change can be induced by an electric field to further cause the change of the surface photonic structure of the film, and consequently, the change of optical properties is induced; the film is formed more evenly, and is controllable in tenacity and strength; due to the special pincushion structure, the contact angle of the polyaniline film is increased and the hydrophilic / hydrophobic change performance of the surface of the film is enhanced.

Description

technical field [0001] The invention relates to a conductive polymer conductive material, which is a polyaniline needle pad array film with electric field response to hydrophilic and hydrophobic changes and a preparation method thereof. Background technique [0002] In the field of conductive polymer research, polyaniline has broad application prospects, mainly because polyaniline has many advantages that other conductive polymer materials cannot match, such as: easy availability of raw materials, diverse molecular structures, excellent physical and chemical properties, reversible properties Acid-base doping and de-doping, controllable electrical and optical properties, etc. Polyurethane has excellent corrosion resistance, abrasion resistance, impact resistance, flexibility and processability. However, since polyurethane itself is a poor conductor of electricity, its antistatic properties are poor. [0003] In recent years, the preparation methods of photonic crystal thin ...
