Communication: The protection of solar energy collecting technology ag
ainst overheating can be achieved using the co-polymer reported here.
In the form of a semi-interpenetrating polymer network, the co-polymer
demixes when the temperature rises above a certain value (which can b
e tuned between 30 and 150 degrees C by adjusting the ratio of the rep
eat units of the components). In the phase-separated state the light t
ransmission of the material is reduced significantly by backward light
scattering.
