Graphene and graphene oxide polymer composite membranes have been shown to effectively remediate wastewater streams. These types of membranes are favorable for their good filtration and for their antimicrobial properties. This study involved the assembly of novel graphene and graphene oxide membranes into non-woven fiber mats using electrospinning techniques. Reological studies were conducted to choose the polymer concentrations most likely to succeed in producing suitable fibers by electrospinning. Once electrospun membranes were produced, the morphological, mechanical, thermal, and hydrophilic properties were determined using various analytical and spectroscopic techniques such as SEM, XRD, FTIR, and Raman. The antimicrobial properties were tested against sewer sludge and cyanobacteria. The properties of electrospun membranes were compared to cast membranes using the same polymer composites. Once characterized, the electrospun membranes were challenged by a suite of simulants to investigate membrane performance for water treatment.
