A novel two‐component physical gel based on interaction between poly(acrylic acid) and 6‐deoxy‐6‐amino‐β‐cyclodextrin

Abstract

Abstract A two‐component physical organogel was produced by interactions of 6‐deoxy‐6‐amino‐β‐cyclodextrin (β‐CDNH 2 ) and poly(acrylic acid). The microstructure and morphology of the gels were characterized by scanning electron microscopy, X‐ray diffraction, and Fourier transform infrared spectroscopy. It was revealed that the intermolecular hydrogen bonds between the molecules of β‐CDNH 2 and the electrostatic interaction between the carboxyl groups of PAA and amino group of β‐CDNH 2 were the main driving forces for the formation and maintenance of the network structures of the gel.
