Nanomaterials refer to new materials that are constructed from a unit structure of one to one hundred nanometers according to certain organizational rules. The purpose of this paper is to apply nanomaterials in the study of visual effects of ethnic dress pattern design. This paper first gives a brief overview of ethnic costumes, including the status quo, development, characteristics of ethnic costumes, and also studies the pattern design and visual effects of ethnic costumes, as well as the image shaping of pattern design. Then, the content of nanomaterials is elaborated. Finally, nanomaterials are applied in the design of ethnic costumes, and they are compared with traditional ethnic costumes, and the functionalities of the costumes and the visual effects of pattern design are observed, respectively. The results show that the overall average score of the visual effect test of ethnic dress pattern design using nanomaterials reaches 8.54 points, which verifies its effectiveness.

Bi4Ti3O12 ferroelectric nanomaterials are mainly used in the manufacture of biosensors, biomedical imaging reagents, or other biomedical applications. Due to the different arrangements of Bi4Ti3O12 ferroelectric nanoparticles, complex nanofibers with specific geometries can be obtained. In this paper, Bi4Ti3O12 ferroelectric nanomaterials were used to study the volatilization state of the acrylic paint used in the coating process. This article explains that some Bi4Ti3O12 nanoparticles were difficult to be dispersed in spinning solution, which made the preparation of composite fibers difficult. Therefore, these issues need further research and resolution. This work proposes to selectively reduce the use of graphene oxide by using an environmentally friendly water solvent to prepare water-reduced graphene oxide (rGO) and then inject octadecylamine into the selectively reduced graphene oxide to prepare octadecylamine-grafted reduced graphene oxide (rG-ODA). The experimental results in this paper showed that through seeding and reduction, functional groups such as carboxyl groups and epoxy groups on the surface of graphene oxide disappeared, and graphene oxide was well reduced. The presence of oxygen-containing functional groups increased the distance between the graphitic layers to 0.713 nm. GS-EDA had a characteristic diffraction peak close to 2θ = 24.3°, indicating that GO was effectively reduced after inoculation reduction.
