Designing Surfactants

The use of cost-effective chemical additives necessitates the interest for new molecular and macromolecular design of surfactants. The webinar will review the origin and classification of surfactants and technology for applications such as detergency, oilfield chemistry, and visco-elastic surfactants.

 

The Park Systems 2019 Material Science Research and AFM Webinar Series continues with New Surfactant Design. New surfactants are introduced when there is an effect cost-performance advantage in any industrial or extraction process or for fundamental research on the interfacial thermodynamic and kinetic behavior that leads to better structure-property and phenomenological understanding. AFM is used in a lot of surface probe manipulation and studies at flat interfaces. New hydrophobic and hydrophilic groups can be investigated including various macromolecular designs. Thus it is ideal for surfactants to be investigated as thin films in Silicon, Gold, or glass substrates by AFM.

Surfactants are ubiquitously used commercially every day. Yet there are still a number of ongoing studies on their use in surface and interfacial chemistry that relate to their dynamic behavior from Langmuir-Blodgett films to micelles. AFM as a tool, and surface probe microscopy methods in general, enable the probing of both small molecule and macromolecular surfactants at interfaces where the surfactants can be highly crystalline ordered or delivered in nanowriting methods with a cantilever tip. This enables the ins-situ and effective molecular probe and manipulation at the thin interface level.
