Analysis of Nanoemulsion Coatings:
This work described a method to understand the dynamics of nanoemulsion coatings. Using a combination of zeta potential measurements, absorption spectroscopy, and fluorescence quenching it is possible to understand how the conformation of molecules at the nanoemulsion change as a function of loading. Conformational changes as a function of pH, temperature and other external inputs are known, but those as a function of coating composition density have not been studied in these systems. The main result is that more coating molecules do not necessarily generate a less permeable coating. The concentration-dependent conformational changes of individual coating molecules has to be taken into consideration, because in some cases it can create unexpectedly highly porous coatings.
