Problems solved by technology

[0011] Although there are many preparation methods for polyaniline, there are generally the following problems: (1) the interfacial polymerization method has the problem of using a large amount of organic solvents and causing environmental pollution; (2) the electrochemical method, ultrasonic radiation method and seed polymerization method have problems The experimental conditions are high and are not suitable for large-scale production; (3) the dilute solution method has a very low polyaniline concentration, which leads to low yie...

Embodiment 1

[0033] 1. Weigh 14mg C 60 Powder, after being ground, dissolved in 5ml of toluene, ultrasonicated for 10min in ice bath; after filtering the above solution, add 5ml of isopropanol to it, put it in a constant temperature incubator at 4°C for 24h to prepare fullerene fiber suspension, Its length is about 10-20 μm, and the scanning electron microscopic analysis (SEM) photo is shown in figure 1 ;

[0034] 2. Measure 1.8ml of aniline (An) and add it to 100ml of HCl with a concentration of 1mol / L, mix and stir; then add 1.14g of ammonium persulfate (APS) to the above solution, stir for 1min, and put it in the refrigerator to control the temperature. Refrigerate at -12°C for 12 hours, add 45ml of ammonia water with a concentration of 1.74mol / L to soak for 5 minutes after suction filtration, and dry to obtain intrinsic polyaniline (PANI-EB) powder, which is ground for use;

[0035] 3. Take PANI-EB powder and dissolve it in N-methyl-2-pyrrolidone (N-methyl-2-pyrrolidone, NMP), sonica...

Embodiment 2

[0039] This example is the same as Example 1, except that the selected good solvent for the polyaniline material is a good solvent for aniline such as dimethylformamide, dimethylacetamide, tetrahydrofuran, and chloroform.

Embodiment 3

[0041] This example is the same as Example 1, except that the selected method for washing out the fullerene fibers is to repeatedly add toluene, filter out insoluble matter, and then repeatedly wash and filter.

Abstract

A fullerene fiber refers to a fibrous fullerene crystal material prepared by connecting fullerene monomers through intermolecular forces. The invention relates to a preparation method for polyaniline micro-nano tubes having the thread-shaped structure and products of the polyaniline micro-nano tubes. The thread-shaped polyaniline micro-nano tubes are prepared by employing the fullerene fiber as a removable template. An operation process comprises the steps: with the aid of a good solvent of polyaniline as a medium, preparing a fullerene fiber/polyaniline composite material by an ultrasonic technology, then employing toluene to carrying out repeatedly centrifugal cleaning to remove fullerene in the composite material, and thus obtaining the thread-shaped polyaniline micro-nano tubes. The method has important guiding significance and practical value for application development of the fullerene crystal material as the template; and due to the unique properties and the unique morphology, the prepared thread-shaped polyaniline micro-nano tubes can be expected to be applied to electromagnetic wave shielding materials, antistatic materials, triodes, strong hydrophobic materials, sensor materials and other fields.

Description

technical field [0001] The invention relates to a method for preparing threaded polyaniline micronano tubes and products thereof, in particular to a method for preparing threaded polyaniline micronano tubes and products thereof by using fullerene fibers as a removable template. The invention belongs to the field of polymer material preparation. Background technique [0002] Polyaniline (PANI) is a polymer synthetic material. Due to the advantages of cheap and easy-to-obtain monomer raw materials, simple synthesis process, excellent electrical conductivity after doping, good stability, and its reversible electrochemical activity, it has become a It is the most practical class of polymer materials, and has shown broad application prospects in many fields. [0003] There are two types of polyaniline synthesis methods commonly used: electrochemical synthesis and chemical oxidation synthesis. The two polymerization methods have their own characteristics, the reaction time is di...
