The Polymer Mechanics Research Laboratory at Auburn University contributes fundamental knowledge to the field of time dependent, thermomechanical behavior of polymers, which contributes to core functions of autonomy in engineered matter, such as sensory mechanisms, actuation capabilities, and adaptive mechanical-material frames. In this talk, we will provide an overview of ongoing research relevant to the multifunctional materials and adaptive structures community, with an emphasis on the deformation and actuation capabilities of polymeric materials and structures. Topics include: (1) mechanics of self-folding polymer origami: we utilize pre-strained polymer sheets that change shape in response to external stimuli. Compactly stored sheets can be transformed into three-dimensional structures on demand. These materials are proposed for use as actuators in deployable space structures. (2) Reconfigurable mechanical metamaterals: tessellated unit cells dictate the macroscopic behavior of the structure. Structures can be reconfigured through thermal and mechanical processes to tailor properties to specific applications. Of particular interest are bistable structures and auxetic metamaterials. (3) Electrospun smart sensors: the use of conducting polymers in the electrospinning processes provides additional functionality to non-woven mats. These sensors are envisioned for use at the human-machine interface. The processing conditions used to fabricate the non-woven mats influence sensor performance and human factors such as breathability. These research activities are broadly conducted by graduate and undergraduate researchers working in a collaborative environment.
