This work deals with the development of a Passive Quartz Crystal Microbalance (QCM) Sensor system for liquid environment to follow the water uptake and drying characteristics of Nafion® polymer membranes. An automated system for the electro-acoustic characterization of a quartz crystal resonator using an impedance analyzer was designed and implemented. The developed system allows carrying out in situ...
With the objective of monitoring the water-uptake kinetics in anti-corrosion cataphoretic paintings, a quartz crystal microbalance (QCM) oscillator sensor was developed based on a 5 MHz AT resonator. The sensor was experimentally characterized with the aim of determining its own sensitivity, phase noise and resolution during the water uptake process. Water uptake of the coating was investigated using...
Water absorption is an essential parameter to define the protection properties of anticorrosive paints. This parameter is often evaluated by means of the dielectric capacitance of the coating. The presence of water in the coating increases its dielectric constant. The semi-empirical Brasher-Kinsgbury equation [1] allows the estimation of a coatingpsilas water uptake through capacitance measurements...
