Self-assembly of colloidal polyelectrolyte-surfactant complexes: from bulk to thin film

We propose an in situ small-angle X-ray scattering study to study the spontaneous self-assembly of colloidal polymer-surfactant complexes and their diverse phase behaviour. Our final goal is to use spontaneous self-assembly in these complex systems to provide a long-lasting antimicrobial property to surfaces, without the need for constant sanitization. The design of this system is based on a concept of fine-tuning solution structure, allowing precise control over coating morphology, which enables creation of long-lasting antimicrobial protections on surfaces. In order to achieve this, we need to main structural features of self-assembled aggregates, which are transferred onto the surface largely undisturbed, as demonstrated by previous GISAXS experiments.
