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. \n\nThis dataset is associated with the following publication:\nZepp, 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.
