The measurement of the diffusion coefficient of water in paints and polymers from their swelling by using an interferometric technique

An interferometric technique has been used to measure the swelling of a paint film caused by its absorption of water vapour. The diffusion coefficient of water in paint is obtained from the time evolution of the thickness of the paint film, when the paint film is subjected to an almost stepwise chan...

Description
Summary:An interferometric technique has been used to measure the swelling of a paint film caused by its absorption of water vapour. The diffusion coefficient of water in paint is obtained from the time evolution of the thickness of the paint film, when the paint film is subjected to an almost stepwise change in the relative humidity of the surrounding air. The measurements were possible in the range of the relative humidity of the air between 50 and 90%.
