Fluorescent labeling and tracking of nanoclay

Author affiliations


We report a methodology developed to detect and track stable fluorescent-labeled nanoclay, in polymer–clay nanocomposite films, and in a contact solvent after migration testing. Fluorescein-5-maleimide (fluorescein) or tetramethylrhodamine-5-maleimide (rhodamine) was covalently bonded to organically modified montmorillonite (o-MMT). Fluorescein- and rhodamine-labeled nanoclay showed good thermal stability up to 220 °C and the rhodamine-labeled nanoclay remained stable at 250 °C. Confocal laser scanning microscopy was used to confirm the tagging and to detect the fluorescent-labeled nanoclays in various systems.
