Synthesis of Core Cross-Linked Star Polymers
Core cross-linked star (CCS) polymer consists of multiple arms tethered on the densely cross-linked core. The discrete core-shell structure of this spherical and hairy nanoobject is constructed via covalent bonds. We are exploring synthesis, compartmentalization, and functionalization of CCS polymers towards Janus functional nanoobjects useful for interfacial and catalytic applications.
Hierarchically Porous Polymers Containing Multiscale Porosity
Constructing a hierarchy of pores spanning from micro- (< 2 nm) and meso- (2 - 50 nm) to macroporous (> 50 nm) length scales allows us to synergistically combine large surface area with fast material transport.
Selective Transport through Nanopores
Nanoporous polymers have promising applications such as filtration, separation, storage, and catalysis. Block polymer self-assembly provides a powerful route to well-defined nanoporous polymers with extraordinary control over pore size, structure, and functionality. We are exploring synthesis of block polymer-based nanoporous polymers and control of transport through nanopores by size for energy and catalytic applications.
