Elemental Sulfur:  A novel, abundant feedstock for polymers and nanocomposite materials

We have pioneered the utilization of elemental sulfur for novel polymers and nanocomposites.  Sulfur is commonly used as a vulcanizing agent in the crosslinking of rubber for tires, however the use of elemental sulfur as the primary monomer, or comonomer for polymeric materials has not been widely explored.  Elemental sulfur is currently produced on the level of 70 million tons annually, the majority of which is thru hydrodesulfurization of crude petroleum.  Consequently, over 6 million tons of elemental sulfur is generated in excess, which creates exciting opportunities to develop new chemistry and processing to utilize sulfur as a feedstock for polymers.   We have invented a new polymerization process, termed, inverse vulcanization, to directly convert elemental sulfur into high sulfur content polymers  (Nature Chemistry 2013), which has since launched this technology as a new field in polymer science. Sulfur exhibits a number of useful properties, such as, high charge capacity for Li-insertion electrochemistry and high refractive index.  However, the chemical modification of sulfur into useful materials remains a difficult technical challenge. Toward this end, we are developing new polymerization and processing methods for the direct utilization of sulfur to prepare thermosetting polymeric sulfur and nanocomposite materials.

High refractive index polymers for infrared optics and photonics

We have pioneered the development of ultra-high refractive polymers derived from the inverse vulcanization of elemental sulfur as the first class of optical polymers for infrared imaging and IR photonics.  These polymers are termed, Chalcogenide Hybrid Inorganic/Organic Polymers (CHIPs) as a hybrid from elemental chalcogenides, such as, sulfur, selenium with organic comonomers.

We have a diverse and highly collaborative research term at the interface of synthetic organic chemistry, polymer chemistry, computational chemistry and optical sciences to prepare novel optical polymers and fabrication of these materials into plastic optics and photonic devices.

Artificial Enzymes for Catalytic Water-Splitting for Clean Hydrogen Production

Metal-containing polymers can combine the useful properties of polymers with the key functions of metal complexes. These metallopolymers are applicable to a wide range of areas such as photovoltaics, stimuli responsive materials and catalysis. Catalysis, for example, includes designing artificial metalloenzymes which can mimic the biological functionalities by engineering the environment of a metal complex using polymeric materials. FeFe-hydrogenase enzyme found in bacteria is an efficient H2 generation catalyst and there has been extensive research on making FeFe-H2ase mimics to produce H2 as a carbon-free energy carrier. We, for the first time, made a metalloinitiator from a FeFe-H2ase mimic to grow polymers via ATRP. The polymers not only provide water solubility and oxygen stability in neutral water but also enhance the activity of the complex by tuning the secondary coordination sphere of the mimic. We will discuss our most recent efforts to synthesize a difunctional metalloinitiator and metallopolymers grafted via ATRP.

Refractive Index Contrast Polymers:  Photoresists for polymer waveguides, interconnects & photonic devices

We have developed a new class of optical polymers, termed, Refractive Index Contrast (RIC) Polymers, which are a class of photoresists that can be used as a “dry-write” film for waveguide and optical interconnect fabrication.  These new optical polymers are designed to enable rapid device component integration of photonic devices for next generation semiconductor chip fabrication.
