Abstract

The invention relates to a micro / nanotube array type nickel biomimetic material and a preparation method thereof. The micro / nanotube array type nickel biomimetic material is characterized in that the biomimetic material is based on a micro / nanotube array of fibrilia bundle templates, and the pipe wall of the micro / nanotube array consists of a nickel nanofilm. The preparation method of the biomimetic material comprises the following steps: firstly, processing fibrilia bundles with a diluted alkali solution or a sodium chlorite and sodium hydroxide aqueous solution to obtain the fibrilia bundle templates of different aggregation morphologies; then, carrying out surface grafting processing on the templates by using amino saline, and putting the templates in a nickel bath for chemical nickel plating; finally, processing the fibrilia plated with a nickel nanofilm by using an NMMO (N-methylmorpholine Oxide) aqueous solution, and removing a fiber matrix to obtain the micro / nanotube array type biomimetic materials of two aggregation morphologies. According to the method disclosed by the invention, the defects that the energy consumption is high and the material structure is easy to control when a biomimetic material is prepared at high temperature are overcome, and the metal nickel biomimetic material which is controllable in morphology can be prepared and has a potential application value in the fields of microreactors, chemical and photoelectric catalysis and the like.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a micro-nano tube array type nickel bionic material and a preparation method thereof. Background technique [0002] Nanoscale materials have excellent physical and chemical properties, but the problems of agglomeration and random arrangement during their preparation and application will reduce the efficacy and usability of materials. The orderly assembly of materials such as nanoparticles, nanowires, nanotubes, and nanofilms is a very important step to improve the performance, efficacy, and application value of nanomaterials, and to accelerate the process of productization. In the product development of micro-nano devices, nanometer and microtube arrays are an excellent structure, and the assembly of nanomaterials through this structure can effectively play the role of materials, and it is easy to make devices. Therefore, the preparation of micro-nanotube arrays with dif...
