Project description

Nanomaterials are a large and heterogeneous group of compounds, natural or manufactured containing particles in an unbound state or as an aggregate, or as agglomerate with size distribution in the size range of 1-100 nm. There is little known about the fate of nanocomposites during service life and end-of-life. In general, polymers will degrade at a slow rate during exposure to indoor/outdoor environments, resulting in a gradual loss of material properties and a slow release of low molecular weight compounds and presumably micro- and nanoparticles into its surroundings. The objective of the project is to investigate how nanosized particles are formed/released during degradation of polymer nanocomposite. In order to manage this, an exposure chamber needs to be designed where the nanocomposite materials can be exposed to various deteriorating environments where the formed/released particles can be collected in a control manner prior to characterization. The method will allow for a controlled sampling of the formed particles at the degraded material surface and subsequent analysis (e.g. size, shape, composition, surface chemistry).
