Soft-imprint alignment processes for patterning liquid crystal polymer layers via contact with a reusable alignment template are described herein. An example soft-imprint alignment process includes contacting a liquid crystal polymer layer with a reusable alignment template that has a desired surface alignment pattern such that the liquid crystal molecules of the liquid crystal polymer are aligned to the surface alignment pattern via chemical, steric, or other intermolecular interaction. The patterned liquid crystal polymer layer may then be polymerized and separated from the reusable alignment template. The process can be repeated many times. The reusable alignment template may include a photo-alignment layer that does not comprise surface relief structures that correspond to the surface alignment pattern and a release layer above this photo-alignment layer. A reusable alignment template and methods of fabricating the same are also disclosed.

Liquid crystal polymers (LCPs) are described herein that include novel arrangements of bio-mimicking properties for use in surgery, therapy, and treatment of medical or comfort issues. Through the particular arrangements medical devices and portions of them may be adapted to have properties that dampen and dissipate vibrations such as shocks to body tissues during surgical recovery and/or during subsequent use. This dampening is attained by novel arrangements of LCP and processes for forming them that vary from prior attempts at synthesizing activated LCP elements. These novel arrangements include using LCP bodies that include thicknesses and properties that have not been demonstrated or achieved for medical or other purposes and that are achieved using distinct processes. These novel LCP arrangements and methods of creating them can produce medical devices that bio-mimic natural tissue or operation to provide better results for patients.
