The increasing scarcity of clean drinking water presents one of the biggest challenges in many developing countries worldwide. There are several heavy metal and biological toxins (including chromium, lead and e coli) that remain in drinking water and have serious, long term health effects. The unique structure and properties of nanomaterials make them effective for remediating heavy metals and other contaminants from polluted water. The purpose of my research was to design and develop a sturdy 3D printed nanocomposite matrix using polymeric polyethylene glycol diacrylate (PEGDA) with embedded silver nanoparticles, that could be used as a commercial water filter to purify drinking water. Infrared spectroscopy, X-ray diffraction, and scanning electron microscope were used to confirm successful synthesis and to characterize the 3D nanocomposite matrix. We are currently exploring a subsequent post treatment with ultraviolet light that promotes the in situ formation of the silver nanoparticles within PEGDA by photoreduction of the metal precursors. We hope to promote the use of 3D printers to develop eco-friendly options for people struggling worldwide to attain clean water sources.
