title: [The new applications of NMR technology in the field of characterization of surface properties of the material].
abstract: Nuclear magnetic resonance (NMR) technology has been developed continuely because of its rapid, accurate and high resolution advantages, The technology has become an important method to analyze the soil properties, and to identify the structure of matters, food analysis, medical imaging fields. This study summarized two aspects of the important applications of NMR in the characterization of the surface properties of materials. First, the use of NMR techniques for the adsorption, desorption and diffusion behaviors of polymer on solid particles (mainly SiO2 particles). Sencond, to investigate the wettability and water uptake progress of contaminated soils using NMR techniques. This study summarized the important applications of NMR techniques in the characterization of surface properties. It also showed the unique application in the field of polymer materials and environment. This study introduced the measured method for the relaxation time of substance using acorn surface area analyzer in the liquid environment. It reflect the surface properties and structural features of substance. It also provided data support for the explanation of environmental behaviors of contaminants and thus, it played an important role in the environmental field. Compared to the conventional BET method, acorn surface area analyzer showed the advantages in terms of conditions and time measurement. Especially, traditional BET method cannot get the information of the specific surface area of substances in the liquid directly, but acorn surface area analyzer solved the difficult problem. It is a new breakthrough in the field of characterization of the surface properties of materials by NMR in the liquid. We analyzed the application of acorn surface area analyzer in pharmaceuticals, cosmetic materials, electronic products because acorn surface area analyzer could reflects the important characteristics of the surface properties and structural features of substance. And we provide the prospective of the applications of NMR techniques in organic matter of soils, drug and natural products detecting.
