Article Synopsis
- The paper explores the creation of large macroporous materials from epoxy resins and polyamines through emulsion polymerization, focused on achieving high fluid permeability and mechanical stability.
- Characterization methods included SEM, nitrogen adsorption, and X-ray photoelectron spectroscopy to analyze the materials' morphology, porosity, and surface chemistry.
- Results indicated that while the materials had high fluid permeability due to interconnected macropores, they displayed a low specific surface area, and all had a high density of hydroxyl groups to enable further functionalization.
Macroporous epoxy-based monoliths prepared by emulsion polymerization have been modified for use in ion exchange chromatography (IEC) of proteins. Strong anion exchange functionality was established by iodomethane quaternization of tertiary amine present on the monolith surface as a part of the polymer backbone. The modification pathway to cation exchange materials was via incorporation of glycidyl methacrylate (GMA) brushes which were coated using atom transfer radical polymerization (ATRP).
