Sahle_SDMP_FRAGMENTATION Epoxy-with MWCNT

Metadata Updated: October 5, 2023

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. Zepp. Fragmentation and release of pristine and functionalized carbon nanotubes from epoxy-nanocomposites during accelerated weathering. Environmental Science: Nano. Royal Society of Chemistry, Cambridge, UK, 10(7): 1812-1827, (2023).
