Problems solved by technology

[0004] However, no method has been found in the prior art to utilize the original hollow structure in the fluff of the cones of the French sycamore tree to prepare fiber carbon materials through simple carbonization. The fiber carbon prepared by this method has a high aspect ratio, self-supporting, Self-welding and other characteristics have broad development prospects

Embodiment 1

[0025] Take two sycamore flocculation cones, wash away the impurities on the surface of the cones with deionized water, and put them in a blast drying oven at 120°C for 24 hours. The cone is cut open with a knife, the fluffy fruit hair is taken, and the seeds are removed to obtain the initial material. The above pretreated materials were placed in a tube furnace and calcined at a constant temperature of 900°C for two hours in a nitrogen atmosphere with a heating rate and a cooling rate of 5°C / min. After cooling to room temperature, they were taken out to obtain the desired material.

Abstract

The invention discloses a self-welding process method of fiber carbon with a high length-diameter ratio, which comprises the steps of taking Platanus orientalis cones, cutting the cones by using a cutter after drying is completed, and taking villus-shaped fruit hairs to obtain an initial material; and dipping the pretreated material into a glycerol solution, and calcining in a tubular furnace at constant temperature for a period of time to obtain the required material. The preparation method is simple and efficient. The invention belongs to the field of preparation of novel carbon materials, and the prepared material has the advantages of high length-diameter ratio, self-supporting, self-welding, environmental protection and the like, so that the material provides huge advantages when being applied to other aspects, and has wide application prospects in the fields of green energy sources, composite materials and the like.

Description

technical field [0001] The invention provides a self-welding method of high aspect ratio fiber carbon, which belongs to the field of preparation of new carbon materials. Background technique [0002] Carbon is a very abundant element in the world, and carbon materials play a vital role in the process of human development. Because of its various electron orbital characteristics and the anisotropy of the crystal itself, it has various properties. With the development of science and technology, the original carbon materials (activated carbon, carbon black, coke, natural graphite, etc.) can no longer meet the needs of social development, so we have developed a variety of emerging carbon materials, such as: carbon fiber, carbon New materials such as nanotubes, graphene, fullerene, etc. [0003] It can be said that carbon materials are closely related to our lives, and have been extensively studied in the fields of mechanics, electrical conduction, heat conduction and chemistry....
