Interactions of thermochromic liquid crystals with surface-modified PET substrates for thermal sensing applications

Key Points

This research aims to explore how surface modifications of PET substrates affect the thermochromic behaviors of cholesteric liquid crystals.
Examined shear-induced and thermally-driven alignment of cholesteric liquid crystals.
Utilized hydrophobic treatments to modify surface properties of PET substrates.
Analyzed thermochromic response of liquid crystals on modified substrates.
Hydrophobic treatment led to increased thermochromic response by reducing ink spreading.
Both shear-induced and thermal alignments were found to contribute to the liquid crystal behavior.

Abstract

Shear-induced alignment and thermally-driven alignment contribute to the thermochromic behavior of the printed cholesteric liquid crystal; Hydrophobic substrate treatment intensifies its thermochromic response by reducing ink spreading.
