The Problem:
Star polymers exhibit unique physical and chemical properties that can be used as a stabilizing agent in complex formulation, cosmetics, and adhesives, whereas linear polymers can be used as membranes to separate components or used in battery fuel cells. Although both are useful, they have restrictions. They are not easily controllable and difficult to synthesize; they both have complex structures and present challenges in characterization, and both may encounter difficulties in processing, such as melt processing, film formation, or creating a desired property.
The Solution:
Researchers at the University of Alabama have developed new compounds and compositions for forming ionic star polymers that are an improvement over conventional (i.e., neutral) star polymers and linear ionenes. These star ionenes provide a more stable charge and are easier to separate than the alternative. These star ionenes allow for improved performance and greater domain compatibility as stabilizing or gelling agents in complex formulations, have more sophisticated structuring, and have dynamic structural behaviors to better absorb other compounds. These have applications in the consumer products such as drug delivery and beauty care. In addition, uses could be applied to the energy sector for battery fuel cells or oil refinement.
