East China University of Science and Technology
The exploration of two-dimensional materials represents a key direction in the field of new materials, and the purity of the solvent directly determines the exfoliation efficiency and performance of these materials. In the research and development of two-dimensional materials such as graphene and MXene, researchers have long been plagued by issues arising from solvent impurities: Moisture and metal ions in conventional solvents can disrupt the layered structure of two-dimensional materials, leading to an increase in material defects and poorer dispersion, which in turn affects the mechanical and optoelectronic properties of the materials. As a result, application research into many two-dimensional materials has struggled to progress due to solvent-related issues, becoming a bottleneck that hinders research breakthroughs.
To address this challenge, the School has introduced a solvent purification system from Beijing Yifeng Technology Co., Ltd. Designed to meet the purification requirements of high-boiling-point solvents such as NMP and DMF, the system features an optimised deep-removal process capable of thoroughly eliminating impurities such as water and metal ions from the solvents, ensuring their purity meets the stringent requirements for the exfoliation and dispersion of two-dimensional materials. Operating in an automated mode, the system enables continuous online purification and supply of solvents, significantly enhancing experimental efficiency whilst eliminating contamination caused by manual handling, thereby ensuring the purity and performance stability of the two-dimensional materials.
The commissioning of the Yifeng Solvent Purification System has opened up new avenues for the institute’s research and development of two-dimensional materials. The purified solvents have significantly improved the dispersibility of two-dimensional materials such as graphene and MXene, substantially reduced flake defects, and fully unleashed the materials’ mechanical and optoelectronic properties, thereby successfully resolving the exfoliation challenges previously caused by solvent impurities. Researchers are now able to focus on the application development of two-dimensional materials, successfully applying them in fields such as flexible electronics and energy storage devices, thereby providing vital support for the development of the new materials industry. With its professional expertise, Yifeng Technology is helping the university achieve continuous breakthroughs in the exploration of two-dimensional materials, fully unleashing their potential and injecting new vitality into scientific and technological progress.
