Title: “Multifunctional Hydrogels as An Emerging Platform for Sustainable Energy and Environment”
Abstract: This talk will present an emerging class of polymeric materials we developed recently: nanostructured conductive polymer hydrogels that are hierarchically porous and structurally tunable. Bottom-up synthetic strategies to rationally design and modify their molecular architectures enable nanostructured hydrogels as a bioinspired material platform to address critical challenges in renewable energy and environmental technologies, beyond their traditional biological applications.
These functional gels as organic building blocks offer an array of advantageous features such as intrinsic nanostructured conducting framework, exceptional electrochemical activity to store and transport ions, and synthetically tunable polymer-water interactions. Several recent advances on these nanostructured hydrogels-enabled advanced energy and environmental applications will be showcased including high-energy lithium-ion batteries and supercapacitors, electrocatalysts, and solar water desalination and atmospheric water harvesting. The ‘structure-derived multifunctionality’ of this special class of materials will be further illustrated.
Bio: Guihua Yu is Mike Walker Associate Professor of Materials Science and Mechanical Engineering at University of Texas at Austin. His research has focused on rational synthesis and self-assembly of functional organic and hybrid organic-inorganic nanomaterials, and fundamental understanding of their chemical/physical properties for advanced energy and environmental technologies.
Yu has published over 140 scientific papers in prominent journals with total citations ~24,000 times and H-index ~77 (Highly Cited Researcher 2018).
