Journal ArticleDOI
The use of elemental sulfur as an alternative feedstock for polymeric materials
Woo Jin Chung,Jared J. Griebel,Eui Tae Kim,Hyunsik Yoon,Adam G. Simmonds,Hyun Jun Ji,Philip T. Dirlam,Richard S. Glass,Jeong Jae Wie,Ngoc A. Nguyen,Brett Guralnick,Jungjin Park,Árpád Somogyi,Patrick Theato,Michael E. Mackay,Yung-Eun Sung,Kookheon Char,Jeffrey Pyun +17 more
TL;DR: A facile method to prepare chemically stable and processable polymeric materials through the direct copolymerization of elemental sulfur with vinylic monomers is reported, which leads to well-defined sulfur-rich micropatterned films created by imprint lithography.
Journal ArticleDOI

Jared J. Griebel,Soha Namnabat,Eui Tae Kim,Roland Himmelhuber,Dominic H. Moronta,Woo Jin Chung,Adam G. Simmonds,Kyung-Jo Kim,John D. van der Laan,Ngoc A. Nguyen,Eustace L. Dereniak,Michael E. Mackay,Kookheon Char,Richard S. Glass,Robert A. Norwood,Jeffrey Pyun +15 more
TL;DR: High quality imaging in the near (1.5 μm) and mid-IR regions using high refractive index polymeric lenses from these sulfur materials was demonstrated.
Journal ArticleDOI
Inverse Vulcanization of Elemental Sulfur to Prepare Polymeric Electrode Materials for Li–S Batteries
Adam G. Simmonds,Jared J. Griebel,Jungjin Park,Kwi Ryong Kim,Woo Jin Chung,Vladimir P. Oleshko,Jenny Kim,Eui Tae Kim,Richard S. Glass,Christopher L. Soles,Yung-Eun Sung,Kookheon Char,Jeffrey Pyun,Jeffrey Pyun +13 more
TL;DR: Sulfur-rich copolymers based on poly(sulfur random-1,3-diisopropenylbenzene) (poly(S-r-DIB)) were synthesized via inverse vulcanization to create cathode materials for Li-S batteries.
Journal ArticleDOI
Interface modification of ITO thin films: organic photovoltaic cells
Neal R. Armstrong,Chet Carter,Carrie L. Donley,Adam G. Simmonds,Paul A. Lee,Michael T. Brumbach,Bernard Kippelen,Benoit Domercq,Seunghyup Yoo +8 more
TL;DR: In this paper, the surface characterization of commercially available indium-tinoxide (ITO) thin films, using photoelectron spectroscopies (XPS and UPS) and electrochemistry of chemisorbed probe molecules such as ferrocene dicarboxylic acid (Fc(COOH)2), 3-thiophene acetic acid (3-TAA), and subsequent modification of these interfaces with electrochemically grown conducting polymer (CP) films is introduced.
Journal ArticleDOI
