Preparation method of bionic high-strength high-flexibility nano composite fiber

Abstract

The invention belongs to the technical field of preparation of light high-strength nano materials and relates to a preparation method of a bionic high-strength high-flexibility nano composite fiber. According to the method, with zirconium oxychloride octahydrate as a raw material, firstly, a nano sheet layer material is prepared, and then by using a wet-method spinning technology, the graphene oxide-zirconium oxide high-strength high-flexibility composite material of a shell-based imitation structure and in a nano scale rule array is prepared. The method comprises the specific steps that (1) astandard buffer solution is prepared at the room temperature; (2) a certain amount of graphene oxide and zirconium salt are added into the solution, the mixed solution is evenly stirred, heated and stirred for 3 hours, and an obtained precipitate is centrifuged and washed; (3) a solidification bath is prepared; (4) the obtained precipitate is prepared into a spinning solution with a certain concentration, the spinning solution is injected into the solidification bath, standing is conducted for 0.5-24 hours, and a gel fiber can be obtained; (5) the gel fiber is washed, dried and subjected to thermal treatment to obtain the bionic high-strength high-flexibility nano composite material.

AI Technical Summary

Benefits of technology

This patented method involves making very thin layers (<100nm) of carbon dioxide on metal foils or other supports made from porous ceramic particles called “porcelain” that act like an insulator for electricity conductors. These tiny sheets have many small holes where gas molecules pass through them when they get inside. By adding water into these holes during this manufacturing step, it becomes possible to create stable structures containing extremely fine layered crystalline silicon carbons. Additionally, there may also include certain chemicals added at specific points along its length to improve their performance. Overall, this new way makes producing high quality single wall carbon quantum dots more efficient than traditional methods involving expensive precursory processes such as laser ablation techniques.

Problems solved by technology

The technical problem addressed by this patented text relates to creating strong yet flexible ceramium oxide (ZrO2) composites suitable for use in applications such as heat insulation or protection against radiation damage caused by nuclear weapons. Current methods involve sintered Zr02 particles mixed together at room temperature before being applied onto other substrate surfaces like steel plating. This method can lead to crackings during manufacturing process, resulting in decreased durability over time.
