Fabrication of magnetized polyester fabric grafted with β -cyclodextrin for controlled release of menthol

The technology of producing a magnetized polyester fabric for controlled and accelerated release of menthol in potential biomedical applications is reported in this paper. The magnetized polyester fabric is prepared in a facile hydrothermal process and subsequently modified with aminopropyltriethoxysilane, grafted with carboxylated β-cyclodextrin, and loaded with menthol under hydrothermal conditions. The microstructure, thermal and magnetic properties of both carboxylated β-cyclodextrins and magnetized polyester fabrics grafted with β-cyclodextrins are characterized by using field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, vibrating sample magnetometry, Fourier transform infrared spectroscopy, thermal gravimetric analysis, differential scanning calorimetry, and diffuse reflectance spectroscopy techniques. It is evident that the carboxylated β-cyclodextrin is synthesized and successfully grafted on the surface of the modified magnetic polyester fabric. Both hyperthermia effect and controlled release behavior of the magnetized polyester fabric loaded with menthol are measured under high-frequency alternating current magnetic fields. It is found that the menthol included in β-cyclodextrin could be released in a controlled and accelerated way under external alternating current magnetic fields.
