This project investigates the synthetic pathway to develop a polyethylene glycol – trifluoromethyl sulfonamide compound to be used as an electrolyte in a proton exchange membrane fuel cell. The inspiration to develop a trifluoromethyl sulfonamide compound tethered to a polyethylene glycol polymer was inspired by the work of David P. Siska and D. F. Shriver in their studies of polysiloxane – trifluoromethyl sulfonamide electrolytes.
In this thesis, I have developed the synthesis of MePEG7-Trifluoromethyl sulfonamide (MePEG7-NHSO2CF3) from monomethylpolyethylene glycol (MePEG7OH). Unfortunately, due to the COVID-19 pandemic, I was unable to complete the depronation and ion-exchange to the Li+ and H+ forms of MePEG7-NSO2CF3- anion. I would have then measured the ionic conductivity of these two species.
