Liquid crystals exhibit versatile alignments that can be modified through various methods, leading to unique optical properties based on their alignment. This characteristic has fueled extensive research including time-temperature indicators (TTIs) systems, which detect and record changes in matter over time and temperature. In this study, we focused on investigating temperature-induced state changes in liquid crystals, specifically 5CB (4-n-pentyl-4'-cyanobiphenyl), with potential applications as TTIs. By injecting a liquid crystal between the PVA and FOTS-coated double film, we initially observed a homeotropic state because of interaction with FOTS. However, over time, the interaction between PVA and the liquid crystal caused a transition to a nematic state, increasing the temperature accelerate the phase transition due to more active interactions. Based on our findings, it suggest that temperature monitoring in liquid crystal-based systems is feasible with TTIs systems.
