Comprehensive Analysis of Crystalline Hydrophobic Alkylated Poly(ethyleneimine)s.

ABSTRACT: Polyethyleneimine (PEI) is a widely used polymer in catalysis, gas separation, water treatment, drug delivery, textiles, and paper production. Carbon dioxide can act as a molecular stimulus for amine-rich polymers such as PEIs, a property that has been exploited in CO₂-mediated desalination. This process entails amine-mediated CO₂ capture and the in situ formation of bicarbonate ions, which subsequently undergo ion exchange with chloride ions present in both model and real seawater. In this study, we prepared a series of alkylated PEIs with different chainlengths (C4-C18) and degrees of alkylation (10-40% alkylation) via simple alkylation as previously reported. The obtained hydrophobic PEI, specifically PEI-C16, was further investigated in terms of its crystalline structure using powder X
