Nowadays as plastic is massively used in various areas, there is a strong negative association regarding the environmental impacts of plastics (e.g., microplastics), so sustainability plays an important role. Therefore, the polymers for various applications should be created based on sustainable resources with recycling possibilities. For example, the use of CO2 as a fundamental building block for the polymers plays an important role.
Polymers can also be used for various applications here. These range from CO2 adsorption to the use as a membrane material for energy storage and converters (e.g., as a membrane in redox flow batteries or as a membrane in electrolysis cells).
