Project Description
Objectives:
- Polymers have a certain Water Vapor Transmission Rate (WVTR) expressed in g/(cm2day) under standard conditions and assuming the transport of the water is diffusion-limited. Usually polymers have a WVTR in the range of 1-10 g/(cm2day).
- The WVTR is a very important property in relation to flexible electronics since in these devices corrosion of metals is often a show stopper in relation to the lifetime of the device. For flexible electronics a WVTR lower than 0,1 g/(cm2day) is needed.
M2i Project:
- Replacement of the so-called MOCON test which is very slow and time consuming.
- Investigate if a MEMS device could be used for this purpose, i.e. measuring water diffusion.
Industrial benefits:
