; polyphenylalanine; porous alumina membranes; surface-initiated ring-opening polymerization (SI-ROP); Introduction
Porous materials with functional surfaces are a topic of immense interest in science and technology. The high surface area and high mechanical stability of such materials allows for applications in
applications. The most common route to graft polypeptides on surfaces is the surface-initiated ring-opening polymerization (SI-ROP) of α-aminoacid-N-carboxyanhydrides (NCAs). Dense polypeptide films consisting of poly(γ-benzyl-ʟ-glutamate), polylysine or polyphenylalanine with thickness in the range between
-grafted gel might be interesting in membrane separation technology or supported drug release/adsorption systems. We investigate the ability of polyphenylalanine to form organo-gels in situ within a porous inorganic environment with respect to different volume fractions of DCM in the solvent mixture. We
