Rieke Metals Polymers Used in Advanced Materials Research

Rieke Metals foundation in active metal production and organic synthesis work led us to manufacture high quality polythiophene polymers. Our reputation for production of polymers has allowed us to serve the material science industry for decades. We continue to be supportive of universities and their ongoing research. This is evidenced as multiple products supplied by Rieke Metals have recently been mentioned in the literature. This includes the two papers below from the Reichmanis’ lab at Lehigh University:

“Carboxyl-Alkyl Functionalized Conjugated Polyelectrolytes for High Performance Organic Electrochemical Transistors”

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10653087/

In this research three of our potassium salt polymers and one of our P3HT’s were used for organic electrochemical transistors (OECTs). The “P3K” polymers displayed the ability to produce OCETs using water as solvent for polymer deposition. Polymer performance was equal to devices produced using more costly and less environmentally solvents.

“Stress-Relieving Carboxylated Polythiophene/Single-Walled Carbon Nanotube Conductive Layer for Stable Silicon Microparticle Anodes in Lithium-Ion Batteries”

https://pubs.acs.org/doi/10.1021/acsaem.4c01132

In this research one of our potassium salt polymers was used for Lithium-Ion Batteries. P3KBuT was added as component of the silicon microparticle coating, leading to a 45% reduction in tensile stress and improved capacity over many numerous battery cycles.
