High-Resolution 3D Direct Laser Writing for Liquid-Crystalline Elastomer Microstructures

Authors


Abstract

The paper describes 3D structures made of liquid-crystalline elastomer (LCE) – rings, woodpiles, etc. – fabricated by two-photon absorption direct laser writing with sub-micrometer resolution while maintaining the desired molecular orientation. These results lay the foundations for creating 3D, micrometer-sized, light-controlled LCE structures.
