Paper Abstract

Transparent, infrared (IR) - reflective coatings are commenly used for energy saving because they protect against heat loss due to radiation through windows. Basic physics tells us that the degree of IR-reflection and the electrical conductance are positively correlated , therefore this type of films is also of interest in the field of electro-magnetic shielding, e.g. for data security or for the protection of operators at work-stations against irritation by ejected dust particles. We have prepared such films consisting of the coating sequence dielectric / silver / dielectric by magnetron sputtering on polymer substrates. We investigated their optical and electrical data after preparation and under the influence of corrosive atmosphere. As a further optional element of protection against film-degradation some of the coatings where overcoated with an organic lacquer of low IR-absorbtance. The details of these investigations will be presented in this paper.
