Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites

Advanced Functional Materials, EarlyView.
Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.

Migration of Ethylene Glycol from Polyethylene Terephthalate Bottles into 3% Acetic Acid

Journal of AOAC INTERNATIONAL, 1980
Abstract Migration of ethylene glycol (EG) from polyethylene terephthalate (PET) bottles into the food simulant 3% acetic acid was studied using 32 fluid oz PET bottles filled with 3% acetic acid and stored at 32° C for 6 months. Final concentration of EG in the 3% acetic acid migration solution was about 100 ppb, which is equivalent to ...
