Summary:

Here, we focus on the development of a novel exposure generation platform which enables the assessment of possible environmental health and safety implications during the incineration scenario of nanocomposite materials. A specific target is the employment of the developed exposure platform for a variety of polymer nanocomposites that are currently in use in many industries and products. A detailed physicochemical, morphological, and toxicological characterization of the released aerosols for each nanocomposite is performed utilizing the developed exposure platform. Biological responses and properties of released aerosol were linked to specific NEP properties and combustion parameters. Through such an understanding, safer-by-design polymer nanocomposites can be manufactured that retain the superior properties without exhibiting adverse effects to the environment and human health.
