Session Abstract

Natural systems are well known for their ability to respond to environmental cues such as heat, light, and humidity in an autonomous fashion, allowing them to accomplish complex tasks such as morphological changes and actuation. Inspired by nature, stimuli-responsive materials have emerged as a new generation of smart materials with potential to influence myriad applications including smart packaging, biomaterials, and textiles, intelligent self-assembly, and actuators such as artificial muscles. This session will highlight leaders in the field of stimuli-responsive polymers, including those working on unique manufacturing methods such as 4D printing. Speakers will share their work on the ties between processing, properties, and performance of advanced polymeric materials such as shape memory polymers, liquid crystalline elastomers, and hydrogels with the ability to respond to temperature, light, or hydration.
