Hierarchial Polymeric Materials Inspired by Nature*

Natural materials, such as spider silk, wood, and seed pods, are excellent models for the design of polymeric systems that respond to complex and interacting environments, and that exhibit controlled and modular mechanical behavior under low energy conditions and with a limited set of chemical building blocks. These bio-inspired strategies provide a rich landscape for innovation, mentorship, and outreach via multidisciplinary, collaborative team science initiated by NSF CAREER-funding in the POL division.  In this context, I will highlight a few examples of how natural systems inspired the design of shape memory materials, injectable gels, and water-responsive composites utilizing principles, such as hierarchy, interfaces, orientation, and dynamics. Collectively, these vignettes offer a framework that provides insight of the interplay macromolecular design, molecular engineering, and robust manufacturing.
