Recently, the Jilin Province Science and Technology Development Plan project undertaken by the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences "conducting cross-linked conductive polymer materials and their application in analytical chemistry" passed the expert appraisal organized by the Science and Technology Department of Jilin Province. The expert group identified that the device is the first in China and the relevant research results are highly innovative and reach the leading level of similar research in China.
Ion detection technology is of great importance in modern industry, biotechnology and environmental protection. For example, with the development of modern industry, a large number of metal cations discharged into the surrounding environment, such as heavy metal cations such as lead and mercury, are extremely harmful to the human body. The detection and treatment of ions has become a very important issue. In the electrochemical analysis of ions, ion selective electrodes have been a commonly used rapid and simple detection method. However, the existing conductive polymer composite film material has disadvantages such as easy peeling off from the electrode surface, swelling, and poor stability of stability. It is extremely important to design and synthesize new materials with high selectivity, high removal efficiency and reusability. It is of great theoretical and practical value for their analysis and detection.
The material electrochemical group led by Niu Li researchers introduced the flexible chain-linked dithiophene monomer into the conductive polymer for the first time, synthesized the flexible chain and the special functional group of the thiophene monomer, and prepared the conductive polythiophene. A novel network-like conductive polymer having a three-dimensionally adjustable cavity molecular structure, which is a functional group based on a flexible chain, directly imparts species selectivity to the body of the conductive polymer film, and a crosslinked structure of a conductive polymer The pore structure in the membrane can be controlled by adjusting the ratio of the polymer monomer and the length of the flexible chain to achieve a selective response to the target species, which is widely used in the fields of analytical detection and separation and enrichment.
They also successfully developed an electrochemical in-situ membrane conductivity measuring instrument, which can combine the electrochemical method with the conductivity measurement of the conductive polymer film, and can measure the change of the conductivity of the film in real time while collecting the electrochemical signal. It is the first in China and has broad market prospects.
