Abstract

Bu çalışmada, kaplama yapmak için ticari olarak temin edilebilen ve 33°C’nin üzerinde yeşilden beyaza, 45°C’nin üzerinde siyahtan beyaza ve 65°C’nin üzerinde maviden beyaza renk değiştiren termokromik pigmentler kullanılmıştır. Farklı sıcaklıklarda ısıl işlem süreci uygulanan kaplamalarda bağlayıcı olarak polivinilpirolidon kullanılmıştır. Hazırlanan kaplamaların renk, faz, mikro yapı analizleri ve kızılötesi termometre ile renk değişim sıcaklıkları karakterize edilmiştir. Yapılan çalışmalar sonucunda günlük hayatta yaşanılan ve yaşam konforunu değiştirmeden olası sıcaklık değişimlerinin ve risklerin bu yöntem ile tespit edilebileceği ortaya konulmuştur.

Temperature Effect in Thermochromic Pigment Containing Coatings

Abstract

In this study, commercially available thermochromic pigments that change colour from green to white above 33°C, black to white above 45°C, and blue to white above 65°C were used to make coatings. Polyvinylpyrrolidone is used as a binder in coatings where heat treatment processes are applied at different temperatures. Color, phase, microstructure analysis and colour change temperatures of the prepared coatings were characterized by infrared thermometer. As a result of the studies, it has been revealed that possible temperature changes and risks experienced in daily life without changing the comfort of life can be detected by this method.
