Embodiment Construction

[0013] Steps:

[0014] 1. Preparation of polystyrene nanoparticles with diameter less than 100 nanometers

[0015] Add 3 to 10 milliliters of styrene and 0.3 to 0.9 grams of surfactant sodium dodecylbenzene sulfonate (SDBS) into 50 ml of secondary water, and place the system on a magnetic stirrer at a constant temperature of 80°C ± 1°C. Stir for 1 hour, then add dropwise 0.2-0.6 g of ethanol (less than 5 ml) solution of initiator azobisisobutyronitrile to the system under continuous stirring, and then react at 80°C±1°C for 8 hours under sufficient stirring conditions. After the reaction, centrifuge with secondary water and absolute ethanol for 3 to 5 times, and wash until the supernatant is colorless. The product was then placed in a vacuum oven at 60°C for 24 hours.

[0016] The above-mentioned initiator azobisisobutyronitrile can also be replaced by benzoyl peroxide, hydrogen peroxide and mixed oxidants.

Abstract

The invention discloses a preparation method of a super-hydrophobic polyaniline / polystyrene composite micro-nano material. The preparation method comprises the following steps: dissolving and dispersing styrene in an aqueous surfactant system, and dropwise adding an initiator to prepare polystyrene nanoparticles with diameter smaller than 100 nanometers; and then adding the polystyrene nanoparticles into a surfactant in which aniline is dissolved and allowing reaction while stirring to obtain the super-hydrophobic polyaniline / polystyrene composite micro-nano material. The preparation method has simple operation, provides obtained polyaniline / polystyrene composite micro-nano tubes with electrical conductivity of polyaniline and toughness of polystyrene as a result of adding the surfactant. And length, width and diameter of the polyaniline / polystyrene composite micro-nano materials can be controlled by adjusting concentration of the surfactant, which provides strong support for fabrication of microelectronic devices.

Description

technical field [0001] The invention relates to a preparation process of a hydrophobic polymer material. Background technique [0002] As a widely studied conductive polymer, polyaniline is widely used in solar cells, electromagnetic shielding, molecular devices, sensors, etc. There are potential application prospects in other aspects. However, due to the difficulty in processing, the promotion of its practical application is limited. Contents of the invention [0003] The purpose of the present invention is to invent a kind of polyaniline material that is easy to process - the preparation method of superhydrophobic polyaniline / polystyrene composite micro-nano material, so that the superhydrophobic polyaniline / polystyrene made by sequential method Composite micro-nano materials can be extended to be both conductive and self-cleaning materials. [0004] In the present invention, styrene is first dissolved and dispersed in the surfactant water system, and the initiator is...
