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 [...]

Surface Chemical Transformations of UV Irradiated Silica-Epoxy Nanocomposites

Gorham J.M., Nguyen T., Bernard C., Stanley D., Holbrook R.D., National Institute of Standards and Technology, US

Silica nanoparticles (SiNPs) incorporated into a polymeric matrix, or silica nanocomposites (NCs), are used in a wide variety of commercially available products in numerous natural and artificial environments. Environmental factors, such as ultraviolet (UV) light, [...]

Investigation of Silica Nanoparticles Accumulated on the Surface of Polymer Nanocomposites Exposed to UV Radiation Using ICP-OES

Rabb S.A., Yu L.L., Bernard C., Nguyen T., NIST, US

Silica nanoparticles are being utilized to enhance the mechanical performance of polymeric materials used in the automotive and construction industries. However, cumulative effects of UV radiation will degrade the polymeric molecules, resulting in a potential [...]
