Form factor of ultra-low crosslinked microgels in overcrowded environments
We propose to use zero-average contrast and tracer-SANS to directly probe the form factors of ultra-low crosslinked (ULC) pNIPAM base microgels in overcrowded environments. For the first time we have been able to synthesize deuterated ULC microgels and we want to use them in ZAC and as matrix where embed few protonated ULC in the tracer experiments. The measurement will be performed at 20C, where the microgels are in the swollen, soft state. The data will. be fitted using the model for fuzzy spheres. This experiment will complete our understanding of the response of super-soft object in overcrowded environments and on the interplay between polymeric and colloidal nature of the ULC microgels.
