Abstract:
Effective pollutant remediation materials require both precise structural control and multifunctional performance. This proposal centers on the design of block copolymer assembles with tunable nanostructures, synthesized via photo-induced atom transfer radical polymerization induced self-assembly (photo-ATRPISA). Key parameters – block length, monomer composition, feed strategy, and crosslink density – will be systematically varied to guide the morphological evolution and optimize adsorption behavior. These assemblies will be crosslinked and post-modified to form porous, water-stable gels featuring cationic character and covalent adaptable networks (CANs), enabling selective PFAS capture and reusability. Alongside performance, environmentally benign design will be addressed through the integration of biobased, degradable, and low-toxicity monomers, supporting green chemistry principles without sacrificing efficacy. Initiator-enabled modifications will introduce added functionality, including magnetic nanoparticles for recovery, photocatalytic units for degradation, and CO2-reactive motifs for carbon capture. Collectively, this work aims to develop responsive, recyclable materials that contribute to sustainable remediation and circular material design.

All interested students and faculty members are invited to attend.
