“…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].…”

“…Although less amount of PET/CDP nanofibers were used compared to PET nanofibers for filtration test, the removal efficiency of the phenanthrene from its aqueous solution was better when PET/CDP nanofibers were used. Water-insoluble CDP can be very effective in removal of many organic pollutants from aqueous media, since CD cavity is capable of forming inclusion complexes with a wide variety of organic molecules [9][10][11]13,18,22,28]. Therefore, the surface modification of electrospun PET nanofibers with CDP increased the efficiency of filtration by facilitating complex formation with phenanthrene compounds.…”

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

“…Therefore, the leaching of cyclodextrin molecules from the fiber surface during adsorption especially in the liquid media was inevitable. However, it is reported that in-situ thermal crosslinking is a simple and effective method to prepare ␤-cyclodextrin based materials by polycarboxylic acids [28].…”

“…As has been reported, b-CD polymers can effectively adsorb organic molecules and heavy metals in water [8][9][10][11][12][13][14][15][16][17][18][19][20]. b-CD polymers modified by carboxyl/carboxylate groups (-COOH/-COO -) have been found to be more efficient in adsorption toward some heavy metals, basic dyes and aromatic amines [21][22][23][24][25][26][27][28][29][30]. The improvements are ascribed to the chemical adsorption properties of carboxyl/ carboxylate groups.…”

Based on the special properties and advantages of b-cyclodextrin (b-CD), b-CD polymers have been widely studied and used in recent years. A lot of researches have focused on the adsorption and separation properties of b-CD polymers. In this paper, b-CD polymer modified by sulfonate groups, which was named S-b-CDP, was prepared using epichlorohydrin as crosslinker and tiron (1,2-dihydroxybenzene-3,5-disulfonic acid disodium salt) as modifier. b-CD polymer without modification, which was named b-CDP, was also prepared for comparison. Infrared spectra, elemental analysis and adsorption tests of S-b-CDP were carried out and compared with b-CDP. The content of sulfonate groups in S-b-CDP was obtained from elemental analysis. The dramatically increased adsorption capability toward methylene blue and basic magenta confirmed the existence and chemical activity of sulfonate groups in S-b-CDP. Due to the convenient preparation process and modified adsorption properties, S-b-CDP will find its applications in various fields such as water purification, drug loading, separation and analysis.
