Language: English (en)
Summary: Liquid crystals (LCs) are a state of matter that posses the qualities of both conventional liquid and solid phases. They have long range positional or orientational order as in a crystal while showing liquid mobility. Molecules that exhibit liquid crystal phases are known as mesogens1. Liquid crystal elastomers (LCEs), also known as solid liquid crystals, are made up of rubbery liquid crystal polymers. LCEs can reversibly change shape in response to temperature changes, electric fields, and even light2. This report will describe how to prepare a thin ( ~ 25 micrometer) liquid crystal gel by photopolymerizing a reactive mesogens. The long-term goal is to build responsive LC nanostructures using a similar technique on top of a micro- or nano-patterned substrate. Practical information regarding sample preparation and characterization will be provided.
