Problems solved by technology

The continuous discovery of assembly methods illustrates the importance of this field. However, these methods still have shortcomings, such as the difficulty of large-scale preparation by LB technology, poor controllability of electromagnetic field-assisted assembly, and relatively complicated equipment. Electrospinning can realize nano The rod-shaped materials are well organized into fibers, but the fibers ejected under high voltage conditions will deposit disorderly on the substrate, so that the nanorod materials are still disordered on the macroscopic scale.

The preparation method comprises the following steps: A) mixing the inorganic wire material with a polymer solution, thereby acquiring a mixed sizing agent, wherein the inorganic wire material is selected from an inorganic nanowire material and / or an inorganic micron wire material; B) using a brush for absorbing the mixed sizing agent, and then coating the surface of a substrate along a certain direction, thereby acquiring the substrate coated with the mixed sizing agent; C) drying the substrate coated with the mixed sizing agent and then separating the substrate, thereby acquiring the inorganic wire material-organic polymer composite material. The invention provides a method forsimply and efficiently configuring the easily large-scale prepared inorganic wire material into a macroscopic ordered structure and prepares the inorganic wire material-organic polymer composite material with a highly ordered structure. The method is not limited to the categories of materials and requires no complex equipment condition.

Description

technical field [0001] The invention belongs to the field of material technology, and in particular relates to an inorganic wire material-organic polymer composite material and a preparation method thereof. Background technique [0002] One-dimensional materials have a wide range of application prospects, but their disordered structure often makes it difficult for them to maximize their performance. Therefore, the highly ordered arrangement of one-dimensional nanowire materials and micron wire materials has always been a hot field of research on the assembly and integration of micro- and nano-materials and later application exploration. [0003] At present, there are many methods for the ordered assembly of one-dimensional materials. The Langmuir-Bougett (LB) technique is a general method for 1D material assembly at liquid-air interfaces. In addition, there are one-dimensional material assembly assisted by magnetic field and electric field, microfluidic assembly technology...
