Abstract:
This talk will present an emerging class of polymeric materials Yu’s group developed recently: nanostructured functional hydrogels that are hierarchically porous, and structurally tunable in terms of size, shape, composition, porosity, and chemical interfaces. 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.
Introduction:
Guihua Yu is Mike Walker Professor of Materials Science and Mechanical Engineering at University of Texas at Austin. He earned Ph.D. from Harvard University, followed by postdoc at Stanford University. 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 many prominent journals with total citations over 23,000 times and H-index ~73. Yu has received a number of notable awards/honors. Yu currently serves as Associate Editor of ACS Materials Letters and is in Advisory/Editorial Board of over 10 prominent international journals such as Chem Chem. Soc. Rev, ACS Central Science, Chemistry of Materials.
