Doctoral student Xiaojie Chen and colleagues from our team, under the joint supervision of Researcher Liangbin Li and Specially Appointed Professor Wei Chen, focused on the application of polyacrylate waterproof composite materials in the field of waterproof coatings. Under harsh service environments such as acid rain, the dynamic evolution of the internal structure of these materials has long been a challenging issue for detection in this field. Our team further developed an in situ characterization technique based on Single-Sided Nuclear Magnetic Resonance (Single-Sided NMR). Taking advantage of its spatial resolution, and in collaboration with BASF Advanced Chemicals Co., Ltd. (Shanghai), we carried out a systematic study on the failure mechanism of waterproof coatings and achieved in situ detection of the erosion process under acidic conditions. The related research findings were published in the journal Analytical Chemistry.
