Polymer Chemistry

n this presentation, we introduce our recent accomplishments

on the integration of tailor-designed polymers for diverse

applications. Hybrid plasmonic nanostructures comprising Au

nanoparticle arrays separated from Au substrate through a

temperature-sensitive poly(N-isopropylacrylamide) linker layer

were constructed, and a unique plasmonic-coupling-based

surface plasmon resonance sensing properties and visible

light active photocatalysis were investigated. Multimetallic

[email protected] nanoparticles consisting of Au core and metal-

containing polyaniline shells were prepared and their bifunctional

electrocatalytic performance was systematically investigated.

Well-defined ordered arrays of plasmonic nanostructures were

fabricated on stretchable poly(dimethyl siloxane) substrates

and tunable plasmon-coupling-based sensing properties were

comprehensively demonstrated upon extension and contraction.

We studied phosphorescence emission enhancement of a purely

organic phosphor system via plasmon resonance energy transfer

by precisely tuning the distance between purely organic phosphor

crystals and plasmonic nanostructures using layer-by-layer

assembled polyelectrolyte multilayers as a dielectric spacer. We

demonstrate a viable laser interference lithography technique

enabling the development of high-performance plasmonic organic

photovoltaic (OPV) devices. Ag nanodot arrays with optimized

configuration embedded in poly(3,4-ethylenedioxythiophene):pol

y(styre-esulfonate) hole transport layer remarkably enhanced the

average power conversion efficiency by ~34.4% compared to the

pristine device. Hierarchically organized porous carbonized-Co

inverse opal nanostructures were synthesized via complementary

colloid and block copolymer self-assembly, where the triblock

copolymer Pluronic P123 acts as the template and the carbon

source. These highly ordered porous inverse opal nanostructures

with high surface area display synergistic properties of high energy

density and promising bifunctional electrocatalytic activity toward

both the oxygen reduction reaction and oxygen evolution reaction

in Li-air battery.
