Weathering Effects on Degradation of Low-Density Polyethylene-Nanosilica Composite with Added Pro-oxidant

Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Catalog Last Checked: August 03, 2026 at 12:49 AM | Dataset Last Updated: August 13, 2018
Nanomaterials are increasingly used in polymer composites to enhance the properties of these materials. Data are presented from a study of sunlight-induced weathering on potential release of nanosilica from a composite with low-density polyethylene (LDPE). Weathering of the composites was determined by quantifying changes in infrared spectroscopic properties (Fourier transform infrared spectroscopy / FTIR); mechanical properties, atomic force microscopy (AFM), scanning electron microscopy and other procedures. This dataset is associated with the following publication: Zepp, R., B. Acrey, M. Davis, A. Andrady, J. Locklin, R. Arnold, O. Okungbowa, and A. Commodore. Weathering Effects on Degradation of Low-Density Polyethylene-Nanosilica Composite with Added Pro-oxidant. Journal of Polymers and the Environment. Springer Nature, New York, NY, USA, 31: 4184–4192, (2023).
