Electrospinning of Cyclodextrin–Pseudopolyrotaxane Nanofibers

Abstract

Spinning a web: The electrospinning of cyclodextrin (CD) pseudopolyrotaxane, α‐CD–PEG‐IC (PEG=poly(ethylene glycol), IC=inclusion complex), nanofibers using poly(ethylene oxide) as a carrier polymer matrix has been achieved (see picture) without destruction of the pseudopolyrotaxane structure. This opens up a variety of possibilities for the development of multifunctional nanofibers containing CD pseudopolyrotaxanes and/or CD inclusion complexes.

Water-insoluble sericin/β-cyclodextrin/PVA composite electrospun nanofibers as effective adsorbents towards methylene blue

“…Due to its special toroid-shaped molecular structure (hydrophobic internal cavity and hydrophilic external surface), it can form noncovalent host-guest inclusion complexes with a variety of solid, liquid, and gaseous compounds [15,16]. This outstanding capability makes it suitable for a wide range of applications such as chemical separations, pharmaceuticals, foods, cosmetics, textiles, etc [17].…”

Correlation of polymer-like solution behaviors with electrospun fiber formation of hydroxypropyl-β-cyclodextrin and the adsorption study on the fiber

“…Their special molecular structure -hydrophobic internal cavity and hydrophilic external surface -can form supramolecular host-guest complexes with a variety of hydrophobic molecules. 25 Recently, Uyar et al have also achieved CD 26,27 and CD-ICs 28 electrospinning fibers without using a polymeric carrier matrix. Therefore, CDs have shown fascinating properties in electrospinning polymeric nanofibers, including CDs, [20][21][22] CD-Inclusion Complexes (ICs), 23,24 and CD-pseudopolyrotaxanes.…”

Molecular filters based on cyclodextrin functionalized electrospun fibers

“…The combination of cyclodextrins and the electrospun nanofibers can potentially increase the efficiency of filters by facilitating complex formation with organic compounds and the very high surface area of the nanofibers. There are only a limited number of studies in the literature that report incorporation of CDs into electrospun fibers for various purposes [16][17][18][19][20][21][22][23]. For instance, ␤-CD have been used to crosslink poly(acrylic acid) nanofibers in order to produce water-insoluble polyelectrolyte nanowebs [16].…”

“…Poly(methyl methacrylate) (PMMA) nanofibers have been electrospun with phenylcarbomylated ␤-CD in order to try to capture organic molecules for waste treatment [20]. In our recent studies we have produced poly(ethylene oxide) (PEO) nanofibers containing cyclodextrin/poly(ethylene glycol) (PEG) inclusion complex [21]. We have also successfully produced electrospun PMMA [22], PEO [23] and polystyrene (PS) nanofibers [24] functionalized with cyclodextrins.…”
