The proposed phase-patterned liquid crystal elastomer can control the isotropic phase locally and manage its transparency. In the process of using a liquid crystal elastomer, the phase of the liquid crystal elastomer region irradiated with the laser can be freely controlled by adjusting the laser process variables (laser power, scanning speed), and various optical and mechanical properties can be controlled accordingly. This product can reversibly implement multi-phase and various patterning in grayscale form beyond the control technologies of previously known liquid crystal elastomers. This product can control the phase by performing secondary cross-linking in a tensioned or heated state using a liquid crystal elastomer that is not completely cross-linked.

The proposed phase-patterned liquid crystal elastomer’s phase transition temperature is about 34 degree, allowing phase transitions to occur through body temperature. this advancement enables information patterns to temporarily disappear when the elastomer becomes transparent upon contact with human skin.

It enables information patterns to temporarily disappear when the elastomer becomes transparent upon contact with human skin and reappear when it is detached and the temperature drops, facilitating reuse. Additionally, the information pattern can be completely erased and replaced, allowing for the recycling of LCE films. and it can also be demonstrated that remote encoding of information patterns through light and show mechanical movement. The materials are considered to use in diverse fields such as actuators, soft robotics, sensors, optical devices, and mechanical damping systems, so it can be applied to diverse field.
