Title:
PREPARATION METHOD FOR FE3O4/MWCNTS-PARAFFIN COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/157399
Kind Code:
A1
Abstract:
The present invention provides a preparation method for a Fe3O4/MWCNTs-paraffin composite material. The preparation method comprises the following steps: step 1, putting a CNT and an acid liquid into a three-opening flask, putting the three-opening flask into an oil bath pan and performing mechanical stirring, performing suction filtration, and performing cleaning by using a great amount of deionized water until the filtrate approximates to a neutral state, so as to obtain an acidified MWCNTs suspension; step 2, adding a functionalized carbon nanotube into a beaker in which the deionized water is contained, and performing ultrasonic treatment to form a stable carbon nanotube suspension, so as to obtain an Fe3O4/MWCNTs heterogeneous structure; and step 3, weighing and putting Fe3O4/MWCNTs and paraffin in the beaker; adding ethyl ether, performing ultrasonic dispersion; after the ethyl ether is completely evaporated, cooling the ethyl ether to a room temperature; putting a sample into a mold; pressing the sample into a cylinder. The preparation method for a Fe3O4/MWCNTs-paraffin composite material, provided in the present invention, has a simple and convenient process, and the prepared Fe3O4/MWCNTs-paraffin composite material has high stability, good coating properties, good crystallinity and very good dielectric properties.
