Abstract:Thermochromism coating was synthesized using triarylmethane leuco dye-based as color former, color developer and alcohols to realize the application for fabric. The effects of mixing solvents, kinds of color former, color developer and solvents on the color and chromatism of the thermochromism coating were analyzed. The color tenability was discussed by adding coatings into thermochromism coating. The results were showed that by adding coatings into thermochromism coating can effectively change the color of thermochromism coating without changing the chromatism temperature; the thermochromism ability can be damaged if the polar between the color former, color developer and solvents was different; color-transition temperature of thermochromism coating that was synthesized using hexadecyl alcohol: lauryl alcohol (mass ratio) = 4:1 was 42 °C. When using hexadecyl alcohol: lauryl alcohol (mass ratio) =3:2, the color-transition temperature of thermochromism coating was 36 °C, indicated changing the solvents ratios can effectively control the color-transition temperature of thermochromism coating.
