Performance and Aging of Graphene Oxide/Polyurethane Nanocomposites

Goodwin Jr. D.G., Bernard C., Stanley D., Nguyen T., Sung L., National Institute of Standards and Technology, US

Graphene oxide (GO) can be used to enhance the properties and extend the service life of polymer nanocomposites (PNCs). GO is a good nanofiller candidate for water-borne polyurethane (WBPU) coatings since GO has outstanding physicochemical [...]

Release of Carbon Nanotubes from Nano-polymer Composites during Environmental Aging

Sahle-Demessie E., Han C., Zhao A., Wang J., Grecsek H., U.S. Environmental Protection Agency, US

Over the past two decades there has been a significant increase in commercial products incorporating engineered nanomaterials (ENM) that are now are used in electronic, cosmetics, automotive and medical products and in environmental applications. Although [...]

Investigating Environmental Weathering of CNF/CNT/ Thermoplastic Polymer Synthesized using Additive Manufacturing

Sahle-Demessie E., Zhao Amy, Stephen Chady, U.S. Environmental Protection Agency, US

Additive manufacturing (aka, 3D printing) is an emerging technology for making a new class of multifunctional nanocomposites for many niche items such as medical implants, and a wide range of industrial designed components. Additive manufacturing [...]

Multi-method analysis of multiwall carbon nanotube polymer nanocomposite after photodegradation

Petersen E.J., Lam T., Gorham J., Scott K., Long C., Sharma R., Sung L.P., Liddle J.A., Nguyen T., National Institute of Standards and Technology, US

Nanomaterials can be used as nanofillers to enhance the properties of polymeric materials. However, the effect of weathering on nanocomposites and the potential for nanomaterial release is not yet well known. This stems partly from [...]
