The symposium will focus on the fundamentals that guide the design of macromolecular complexes whose structure enables removing/separating a large range of pollutants from air, water and soil. Polymers and polymer-particulate complexes exhibit a rich variety of responsive morphologies that drive their function. The chemistries of these complexes play a dual role, including formation of binding sites as well as driving of the morphologies that enable capturing and separation of substances (gases, impurities, contaminates). With the ability to tailor multiple functionalities in macromolecules and blend them with functional particles such as coated nanoparticles and metal organic frameworks, they present the basis for many current and potential new tools for cleaning the environment. To push the envelope of the current state of the art an immense effort is on the way to design complex polymeric media that will enable not only effective capture of undesirable substances but also be re-processable and environmental friendly. Multidisciplinary approaches to the design of new polymers and their complexes, the dynamics within the complexes and the impact of the polymer morphology on their functionality will be discussed.
