Material surface performance testing technology plays an important role in the research and application of chemistry, especially in university chemistry experimental teaching. These technologies provide students with opportunities to deeply understand the surface characteristics, structure, and chemical behavior of materials. This article focuses on the commonly used surface performance testing techniques for materials, such as scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), contact angle measurement, surface plasmon resonance (SPR), and Raman spectroscopy. It analyzes their practical applications in university chemistry experiments and their impact on improving students' experimental abilities and scientific research literacy. By introducing these advanced detection techniques in experimental teaching, not only can students enhance their understanding of the microstructure and chemical reaction mechanism of material surfaces, but they can also help them master the commonly used technical means in modern scientific research, laying a solid foundation for future scientific research work.
