Solar energy absorption by acrylic coatings—II: the effect of alternating environmental conditions

Atmospheric corrosion of building materials is an enormously complex and interdisciplinary process. It affects not only the ability of building to perform over the prolonged period of time but also the overall energy consumption. The presented paper is a part of a larger study on application of acrylic plasters in passive solar systems. Absorption characteristics as well as microstructural features of acrylic plasters subjected to alternating climatic conditions have been analysed. In order to simulate the real conditions, samples were exposed to the variations of temperature and humidity, near-daylight radiation (xenon lamp) and subjected to acid and alkaline environments.
