Embodiment Construction

[0017] The present invention provides a preparation method of PANI / Fe3O4 / MWCNTs-paraffin wax composite material. In order to make the purpose, technical scheme and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] like figure 1 As shown, in the examples, this example includes the functionalization of MWCNTs, the preparation of PANI / Fe3O4 / MWCNTs heterostructures and the preparation of PANI / Fe3O4 / MWCNTs-paraffin composites.

[0019] Among them, the functionalization process of MWCNTs is as follows:

[0020] Although carbon nanotubes have excellent physical and chemical properties, due to the strong van der Waals force between carbon nanotubes, they are prone to agglomeration, which seriously affe...

Abstract

The invention provides a preparation method of a PANI / FE3O4 / MWCNTs-paraffin composite material. The method comprises the steps that CNT and an acid solution is placed into a three-month flask, the three-month flask is placed into an oil bath pan to be mechanically stirred for several hours, suction filtration is performed, a sample obtained after filtering is performed is put into a drying oven, and an acidified MWCNTs suspension is obtained; a functionalized carbon nano tubes are added into a beaker to perform ultrasonic treatment, a stable carbon nano tube suspension is obtained, 20 ml of 157 mg (0.4 mmol) (NH4)2FeSO4-6H2O and 386 mg (0.8 mmol) of NH4Fe(SO4)2-12H2O are added to continue to perform ultrasonic treatment, and a Fe3O4 / MWCNTs heterostructure is obtained; 0.02 g of Fe3O4 / MWCNTs and 0.8 g of paraffin are added into the 100 ml beaker, 20 ml of diethyl ether is added for performing ultrasonic dispersion, after diethyl ether is evaporated completely, cooling is performed to the room temperature, the sample is put into a mold, and a cylinder is obtained through pressing. Compared with the prior art, the obtained PANI / FE3O4 / MWCNTs-paraffin composite is uniform in surface coating, the structure is orderly, and meanwhile the dielectric property is good.

Description

technical field [0001] The invention relates to a preparation method of PANI / Fe3O4 / MWCNTs-paraffin wax composite material, which belongs to the field of nanometer material preparation. Background technique [0002] Polymer / inorganic nanocomposites, due to their combination of good flexibility, processability, high modulus, thermal conductivity and other properties of polymers, and the unique magnetic properties, electrical properties, and optical properties of magnetic particles, have caused electromagnetic waves. Shielding is of concern in the field of microwave absorption and has wide applications in electromagnetic shielding, electrochromic devices, and nonlinear optical systems. Due to its variable structure, special doping mechanism, excellent environmental stability, and processability, polyaniline has potential applications in the field of electromagnetic shielding. Ferroferric oxide has good magnetic properties and electrical conductivity, but the environment The ...
