Analyzing the intrinsic connection between Chinese calligraphy creation and brush properties from a micro perspective

Abstract Artists often assess that Chinese brushes’ performances rely on macroscopic writing experience, while they seldom consider the underlying reasons for differences from experimental science. However, the correlation between materials and writing performance can be utilized to advance brush materials and develop traditional Chinese calligraphy. In this study, we examined the provenance of the diverse range of natural or man-made fibers and hairs. The hairs of herbivores, such as sheep and rabbits, exhibit a superior layered structure and a reduced level of grease, which provides an explanation for the microscopic level at which rabbit hair has become a popular brush material. The subsequent incorporation of polydopamine markedly enhanced the ink absorption capacity of the rabbit hair Chinese brush, exhibiting a remarkable degree of responsiveness and ink adsorption stability during creation. Our results indicate a significant correlation between brush writing performance and material selection, which provides guidance for the modern creation of calligraphy art.
