Amine- and Ammonium-Modified Silicones for Direct Air Capture of CO2
Background The field of carbon dioxide (CO2) capture is rapidly growing due to an increasing need to effectively remove CO2 from the atmosphere. New technologies are currently being developed to target CO2 in various types of sources. One particular method of CO2 capture that has gained traction in recent years is membrane-based separation, which is...

Catalyzed Aminolysis of Polyesters (Microfibers, PET Bottles) Using Long Chain Alkyl Amines
Background Polyethylene terephthalate (PET) plastics are some of the most widely used, yet one of the largest plastic polluters globally. PET polymer is the primary component of disposable water bottles, and is a main component in the textile manufacturing industry. These products typically end up in waste dumps and landfills, and are seldom recycled. There...

Modification of Textiles and Fabrics with Moisture-Swing Moieties for CO2 Capture
Background In the wake of the climate crisis, the necessity of removing carbon dioxide (CO2) from the atmosphere is of utmost importance. Current methods for removing CO2 from the atmosphere include Direct Air Capture (DAC) which uses a chemical filter that selectively binds to CO2 molecules. Once captured, the concentrated CO2 stream is then stored...

Zwitterion Functionalized Copolymers for Reverse Osmosis Brine Desalination using Pervaporation
Background Access to clean water resources has accelerated research in the direction of membrane-based separation processes, like reverse osmosis (RO), that are often perplexed by acute saline feeds and pervasive membrane fouling. The properties of the polymeric membranes deployed in these operations play a critical role in understanding their degradation...

Reprocessable Sorbents for Direct Air Capture of CO2
Background Negative emission technologies, including direct air capture (DAC), are a critical solution needed to reduce carbon emissions and lead to a net-zero scenario. DAC solutions are a viable solution that present many advantages, but generate increased demand for low-cost CO2 sorbents, due to greater amounts of material needed to effectively...

AUDACity: DAC Polymer-Enhanced Cyanobacterial Bioproductivity
Background Carbon dioxide removal (CDR) methods from atmospheric air, including direct air capture (DAC), is essential to limit the spread of global warming. However, current DAC approaches based on thermal and pressure swings are very energy intensive. Moisture-driven DAC using strong-base anion exchange resins (AER) reversibly binds CO2 from ambient...

Multiblock Copolymers for Moisture Swing Direct Air Capture
Background Polysulfones have been increasingly studied in recent years as a class of thermoplastics with excellent strength and thermal stability used in nanofiltration, energy storage, and biochemical separation. Quaternary ammonium polymers are another class of materials that tend to have high conductivity and good ion exchange properties. Copolymers...

Poly(Tetramethylene Oxide)-Based Segmented Ionenes Block Copolymer with Aliphatic or DABCO Hard Segments
Background Ionenes contain charges in their polymer backbones, as opposed to traditional ionomers that have charges on the pendant site of the backbone. Ionenes, whether positive or negative, typically fall into two categories- either segmented or non-segmented. Segmented ionenes contain alternating hard and soft segments along the polymer backbone,...
