Detection and Quantification of Graphene Family Nanomaterials in the Environment

March 5, 2018
Author(s)
David Goodwin, Adeyemi Adeyele, Li Piin Sung, Kay Ho, Robert Burgess, Elijah Petersen
An increase in production of commercial products containing graphene-family nanomaterials (GFNs) has led to concern over their release into the environment. The fate and potential ecotoxicological effects of GFNs in the environment are currently unclear

Impact of UV irradiation on multiwall carbon nanotubes in nanocomposites: formation of entangled surface layer and mechanisms of release resistance

January 31, 2017
Author(s)
Tinh Nguyen, Elijah J. Petersen, Bastien T. Pellegrin, Justin M. Gorham, Thomas F. Lam, Minhua Zhao, Li Piin Sung
Carbon nanotubes (CNTs) are increasingly used in consumer and structural polymeric products to enhance a variety of properties. Under weathering, the polymer matrix will degrade and the nanofillers will potentially be released from the products, which

Investigating the Process of Surface Degradation and Nanoparticle Release of a Commercial Nanosilica / Polyurethane Coating Under UV Exposure

March 11, 2015
Author(s)
Deborah S. Jacobs, Yu L. Cheng, Savelas A. Rabb, Peter J. Krommenhoek, Lee L. Yu, Tinh Nguyen, Li Piin Sung
Considerable research has shown that many coatings properties such as mechanical, electrical, and ultra violet (UV) resistance are greatly enhanced by the addition of nanoparticles, which can potentially increase the use of nanocoatings for many outdoor

Characterization of Airborne Nanoparticle Released from Consumer Products

December 1, 2014
Author(s)
Andrew K. Persily, Liang Chung J. Lo, Steven J. Nabinger, Dustin Poppendieck, Li Piin Sung
Polymer and other coatings are commonly used to protect, enhance, or decorate wood, plastic and metal products used in homes and other buildings. Nanoparticles (i.e., particles having at least one dimension smaller than 100 nm) are increasingly being added

Mechanisms of aging and release from weathered nanocomposites

October 31, 2014
Author(s)
Tinh Nguyen, Wendel Wohlleben, Li Piin Sung
Polymer nanocomposites are increasingly used in outdoor structures. However, polymers are susceptible to degradation by solar ultraviolet (UV) radiation, which potentially releases nanofiller during polymer nanocomposites' life cycle. Such release may pose
