Termokromik Malzemelerin Kaplama Malzemesi Olarak Karakterizasyonu
Abstract
Controlling the amount of solar energy entering the building, reducing the energy needs of buildings is a measure that can be taken to combat global warming. For this purpose, the windows are covered with special thin film which is effective on energy conservation. There are a lot of application for intelligent coatings, including greenhouses, sun protectors, housing, offices and automobile windshields. The development of such coatings provides environmental benefits leading to considerable savings in energy costs [1]. Researches have led to the development of new generation materials. Developments in materials technology gained extra functions that cause the term "intelligent material" to give the desired response to some conditions such as temperature, light, etc. Improving on produce a new generation of thermochromic intelligent glasses that control the light and heat energy by changing the optical properties depending on the changing temperature. In this study, it is aimed to develop innovative coating materials for applications which will reduce external dependence on glass used especially in the construction sector, increase competitiveness at international level and support energy efficiency. The grain size of the thermochromic pigments, which change color at 33°C green, black at 45°C, and blue at 65°C, were measured and TG/DTA analyzes were carried out. Pigments were examined with USB digital microscope and color measurements were made using spectrophotometer. The color change of thermochromic pigments with increasing and decreasing temperature was examined by infrared thermometer. Characterization studies were carried out by X-ray diffraction analysis and scanning electron microscopy analysis techniques.
