Method and system for characterizing of charge property of polyelectrolyte brush-layer grafted on channel wall

摘要

The present invention relates to a method and system capable of evaluating the charging characteristics of a brush layer formed by grafting an electrolyte polymer onto a channel wall. According to the present invention, in measuring the electrostatic potential distribution, surface potential, and total charge density, which are the charge characteristics of the brush layer grafted with the electrolyte polymer, a zeta potential measuring instrument and an atomic force microscope (AFM) are complex. It can predict, control, and evaluate more simply and accurately compared to the previous method, which requires expensive and expensive equipment.
