Abstract

A flat tape composed of several hundreds of silica filaments was used as a carrier for the thermochromic dye bis (diethylammonium) tetrachloridocuprate (II) (DEA-CuCl₄) and coated with a methyl silicate resin. The thermal transition of the created composite was around 42 ℃ and its surface color change was mainly influenced by the low thermal conductivity of silica fibers. In addition to thermochromic behavior, the composite also exhibited electrical properties. Measurements indicate that in the temperature range of 4 to 24 ℃ the dye behaves as a semiconductor, while at higher temperatures it exhibits behavior of conductor. This pilot study suggests the sensory potential of the DEA-CuCl₄ dye, which provides both a visual color and electrical responses to a thermal stimulus.
