Water scarcity and quality challenges facing the world can be alleviated by Point-of-Use filtration devices (POU).
The use of filtration membranes in POU devices has been limited largely because of membrane fouling, which occurs when suspended solids, microbes, and organic materials are deposited on the surface of filtration membranes significantly decreasing the membrane lifespan, thereby increasing operation costs.
There is need therefore to develop filtration membranes that are devoid of these challenges.
In this work, nanotechnology was used to fabricate nanostructured polyamic acid (nPAA) membranes, which can be used for microbial decontamination of water.
The PAA was used as support and reducing agent to introduce silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) with antimicrobial properties.
The nPAA membranes were fabricated via thermal and wet phase inversion technique and then tested against Escherichia coli and Staphylococcus aureus following standard tests.
The resulting nanoparticles exhibited excellent dispersibility and stability as indicated by the color change of the solution and increments of optical density at 415 nm for AgNPs and 520 nm for AuNPs.
The wet phase inversion process used produced highly porous, strong, and flexible nPAA membranes, which showed well-dispersed spherical AuNPs and AgNPs whose rough average size was found to be 35 nm and 25 nm, respectively.
The AgNPs demonstrated inhibition for both gram positive E.
coli and gram negative S.
aureus, with a better inhibitory activity against S.
aureus.
A synergistic enhancement of AgNPs antimicrobial activity upon AuNPs addition was demonstrated.
The nPAA membranes can thus be used to remove microbials from water and can hence be used in water purification.
