Non-covalent marriage of β-cyclodextrin-polyethylene glycol and functional polyacrylamide via host–guest interaction: construction, characterization and performances

This paper reports the non-covalent marriage of bridged β-cyclodextrin and functional acrylamide polymers via host–guest interactions. The structure of supramolecular polymeric systems (polymer/bis-CD) was determined by FT-IR, 1 H NMR and SEM. The XRD and thermal analysis were carried out to further validate the formation of the inclusion complex. This interesting host–guest system could significantly enhance the acrylamide polymer's performance with good viscosity property and shear resistance, high salt tolerance, thermo responsive behavior, and surfactant compatibility, which indicate potential applications in many fields.
