Abstract

Cellulose ribbons, when produced from liquid crystalline solutions, exhibit a remarkable responsiveness to moisture. Cellulose-based Nature inspired materials have significant potential for opening up new routes for the production of novel mobile soft materials with tremendous impact on intelligent textiles, energy generation, drug delivery, bio-medical and bio-sensing devices, and micro soft robotics. This work focuses on the development and evaluation of stimuli-responsive cellulose-based liquid crystalline films, using for example, shear-casting techniques employing a multi-layered design. The applicability of these films as flexible humidity and temperature sensors will offer a significant contribution to the LC field.
