石英晶体微天平在高分子研究中的应用

Quartz crystal microbalance (QCM) has been widely used in polymer research as a powerful characterization tool. In this article, the author introduces the brief development history, basic principle and experimental sample preparation method of QCM. On this basis, it is introduced how to study the conformational behavior of interfacial grafted polymers, the ionic effect of polymers and polymer marine antifouling materials based on quartz crystal microbalance with dissipation monitoring (QCM - D) and related combined techniques, demonstrating the broad application prospects of QCM - D technology in polymer research. QCM - D can simultaneously detect the mass change and rigidity change of the interfacial polymer film, thus reflecting its structural change. After being combined with a spectroscopic ellipsometer, it can also synchronously obtain information such as the thickness change of the interfacial polymer film, which can effectively solve the problems in relevant polymer research. It is hoped that this article can play a certain enlightening role in how to use QCM - D technology to conduct polymer research, so that this characterization technology can solve more problems for polymer research.
