Abstract

The invention relates to a simple and feasible scanning electrochemical microscope test method. The method comprises the following steps: processing a large-sized electrolytic tank made of a polytetrafluoroethylene material, and stably sealing a test sample by using thermosol. The test sample has the characteristics of fast curing, non-pollution, non-toxic and high viscous force, has certain hardness, flexibility and re-viscidity, can be heated and melted again for use. The electrolytic tank is stabilized on a sample stage loading plate, and the edge of the test sample placed at the bottom ofthe electrolytic tank is sealed by using the thermosol. By adoption of the simple and feasible scanning electrochemical microscope test method provided by the invention, large-sized samples with multiple specifications can be tested, the maximum test area is 50mm*50mm, and the test sample can be a metal substrate, a test sample with film layer and coating and other test samples subject to other experiments, and can be square, circle, block, plate and other shapes. After the test is completed, the sample can be taken out just by smelting the thermosol again, thereby ensuring the integrity and reusability of the sample, improving the utilization rate of SECM and expanding the application scope and field of the SECM. The test method is simple and feasible and is easy to operate.

Description

technical field [0001] The invention relates to a simple and feasible scanning electrochemical microscope test method. Background technique [0002] Scanning Electrochemical Microscopy (SECM) was invented in 1989 and obtained a U.S. patent. It is based on the development of Ultra Micro Electrode (UME) and Scanning Tunneling Microscope (STM) by A.J.Bard Group of University of Taxes at Austin Department of Chemistry and CH Instruments. A new electrochemical on-site detection technology with a resolution between the ordinary optical microscope and STM has been produced, and the commercialization of the scanning electrochemical microscope has been realized, so that this powerful research method has entered more experiments room. Scanning Electrochemical Microscopy is based on the principle of electrochemistry and measures the electrochemical current given by the oxidation or reduction of chemical species. In addition to giving the topography of the sample surface, SECM can obs...
