When nanomaterials added to consumer products create products with improved properties. However, it is necessary to evaluate the potential of adverse impacts on the environment and the human health. This study has shown there is strong evidence that the stability of two types of food packaging low density polyethylene (LDPE)-clay composite films are altered when exposed to environmental conditions, UV-irradiation or ozone in the presence of moisture. Both LDPE samples underwent oxidative degradation during UV irradiation or ozone exposure resulting in a substantial change in physical, structural, and thermal properties releasing clay nanoparticles.

Degradation kinetics of nanocomposite in the environment. Nano-polymer composites are exposed to sunlight and oxidizing conditions that cause weathering of the polymers, leading to degradation and the release of nanoparticles. This dataset is associated with the following publication: Han, C., E. Sahle-Demessie, A. Zhao, T. Richardson, and J. Wang. Environmental aging and degradation of multiwalled carbon nanotube reinforced polypropylene. CARBON. Pergamon Press Ltd., New York, NY, USA, 129: 137-151, (2018).

Data include changes in aging of weathered materials using optical macroscopy, Raman and FTIR spectroscopy, thermogravimetric analysis and Scanning electron microscopy. The release of fragments and particles were determined using imaging methods. The influence NPs interaction with the polymer matrix on their environmental release has not been well studied. The current paper focuses on some analytical techniques suitable for evaluating the effects of weathering on the detection and characterization of NPs, including Fourier transforms infrared spectroscopy (FT-IR), optical microscopy, contact angle measurements, gravimetric analysis, confocal microscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM) and Raman spectroscopy. The study also includes the toxicity of released particles and organic compounds. This dataset is associated with the following publication: Sahle-Demessie, E., C. Han, E. Varughese, B. Acrey, and R.
