Grafting of cyclodextrins onto polypropylene nonwoven fabrics for the manufacture of reactive filters. I. Synthesis parameters

A novel method for the preparation of immobilized α-, β-, and γ-cyclodextrins (α-, β-, or γ-CD) on polypropylene (PP) nonwoven fabrics is presented. These new materials were prepared by graft-polymerization of glycidyl methacrylate (GMA) onto PP filters using the electron-beam technique, followed by coupling of α-, β-, and γ-CDs with the epoxide group. Optimization of various reaction parameters such as time, temperature, irradiation dose, monomer, and CD concentration was carried out.
