“…Compared with the FT-IR spectra of ␤-CD, the FT-IR spectra of GCD is similar. Some characteristic absorption peaks of ␤-CD at 857, 946, 1028 and 1159 cm −1 have been also found in the FT-IR spectra of GCD [17], which indicates that cavity structure of ␤-CD was kept in GCD molecular. In addition, absorption peaks obviously shifted to higher wave number and ranged widely between 3500 and 3100 cm −1 .…”

“…CDP was formed as a three-dimensional network structure onto PET nanofibers. Due to crosslinked structure, the CDP is stable and water-insoluble [27,28]. Thereby, surface modification of CDP onto PET nanofibers is permanent and can resist to leaching or washing process [21,24,25,29].…”

Cataloged from PDF version of article.Surface modified electrospun polyester (PET) nanofibers with cyclodextrin polymer (CDP) were produced (PET/CDP). CDP formation onto electrospun PET nanofibers was achieved by polymerization between citric acid (CTR, crosslinking agent) and cyclodextrin (CD). Three different types of native CD (α-CD, β-CD and γ-CD) were used to form CDP. Water-insoluble crosslinked CDP coating was permanently adhered onto the PET nanofibers. SEM imaging indicated that the nanofibrous structure of PET mats was preserved after CDP surface modification process. PET/CDP nanofibers have shown rougher/irregular surface and larger fiber diameter when compared to untreated PET nanofibers. The surface analyses of PET/CDP nanofibers by XPS elucidated that CDP was present on the fiber surface. DMA analyses revealed the enhanced mechanical properties for PET/CDP where PET/CDP nanofibers have shown higher storage modulus and higher glass transition temperature compared to untreated PET nanofibers. The surface area of the PET/CDP nanofibers investigated by BET measurements showed slight decrease due to the presence of CDP coating compared to pristine PET nanofibers. Yet, it was observed that PET/CDP nanofibers were more efficient for the removal of phenanthrene as a model polycyclic aromatic hydrocarbon (PAH) from aqueous solution when compared to pristine PET nanofibers. Our findings suggested that PET/CDP nanofibers can be a very good candidate as a filter material for water purification and waste treatment owing to their very large surface area as well as inclusion complexation capability of surface associated CDP

“…(2009) studied the FT‐IR spectra of waxy potato starch crosslinked with adipic acid and acetic anhydride, and they reported that a new absorption band at 1732 cm −1 , corresponding to C = O stretching vibration, can be observed in the only crosslinked starch, as compared to the native starch. According to Zhao et al. (2009), the unique band at 1706 cm −1 in the present study explains the C=O stretching vibration of ester groups and carboxyl groups in the β‐CD samples.…”

This study was conducted to investigate the structural characterisation of b-cyclodextrin (b-CD) crosslinked by adipic acid. b-CD was treated with different concentrations (0%, 5%, 10% and 15%, w ⁄ v) of adipic acid. Different instruments, such as scanning electron microsope (SEM), Fourier-transform infrared (FT-IR) spectroscopy and 1 H and 13 C nuclear magnetic resonance (NMR) spectra were used to find out chemical structure in the crosslinked b-CD. SEM analysis suggested that crosslinking b-CD with 15% adipic acid changed the original morphology and considerably increased the particle size of the raw material. FT-IR spectroscopy data showed that an intensive absorption band at 1706 cm )1 was present in the b-CD samples treated with 10% and 15% adipic acid, indicating a crosslinking between hydroxyl groups of b-CD and carboxyl groups of adipic acid. NMR spectra revealed that the ester linkages between hydroxyl groups of b-CD and carboxyl groups of adipic acid were formed after crosslinking of b-CD with adipic acid.
