An unbroken cold chain is crucial for health, impacting vaccines, medical products, and daily food. Effective management and cost-efficient monitoring are challenging. Polymer micelles, such as the pentablock copolymer (qPDMAEMA85-PEO130-PPO44-PEO130-qPDMAEMA85), can serve as inexpensive indicators of refrigeration breakdown. By deeply understanding the micellization of this non-equilibrium system, we aim to develop a system for temperature-dependent and irreversible colloidal aggregation, indicating temporary heating above a threshold temperature. We use a micellar system with iron species at the centre of a flower-like micelle, previously shown to undergo irreversible aggregation upon heating. However, the process is not fully understood. Introducing Prussian blue nanoparticles can influence this aggregation, inhibiting its irreversibility. We plan to perform ASAXS measurements to investigate the location and role of the iron species during these processes in detail.
