Electrospinning of cyclodextrin functionalized poly(methyl methacrylate) (PMMA) nanofibers
Cyclodextrin functionalized PMMA nanofibers (PMMA/CD) were successfully produced by electrospinning technique with the goal to develop functional nanowebs. Bead-free uniform electrospun PMMA/CD nanofibers were obtained from a homogeneous solution of CDs and PMMA in dimethylformamide (DMF) using three different types of CDs, a-CD, b-CD and g-CD. The electrospinning conditions were optimized in o...
متن کاملElectrospun zein nanofibers incorporating cyclodextrins.
Zein nanofibers containing cyclodextrins (zein/CD) were produced via electrospinning. Three types of CDs (α-CD, β-CD and γ-CD) having 10%, 25% and 50% (w/w) were individually incorporated into zein nanofibers. SEM imaging elucidated that the morphologies of the electrospun zein/CD nanofibers depended on the CD type and weight percentage. The incorporation of CDs in zein improved the electrospin...
متن کاملFTIR study of modification of transition metal on zeolites for adsorption
Adsorption of 1-propanethiol on Co and Cd modified, synthetic (3A, 4A and 13X) zeolites were studied by FTIR (Fourier Transform Infrared) spectroscopy and SEM-EDX (Scanning Electron Microscope-Energy Dispersive X-Ray) graphics. Amount of metal cations on mentioned zeolites was measured by AAS (Atomic Absorption Spectrometer). Based on divalent cations of zeolites, it was assumed that cations ma...
متن کاملThe formation and characterization of cyclodextrin functionalized polystyrene nanofibers produced by electrospinning.
Polystyrene (PS) nanofibers containing the inclusion complex forming beta-cyclodextrin (beta-CD) were successfully produced by electrospinning aimed at developing functional fibrous nanowebs. By optimization of the electrospinning parameters, which included varying the relative concentration of PS and beta-CD in the solutions, bead-free fibers were produced. Homogeneous solutions of beta-CD and...
متن کاملElectrospinning of cyclodextrin functionalized polyethylene oxide (PEO) nanofibers
By means of the electrospinning technique we have successfully synthesized cyclodextrin (CD) functionalized polyethylene oxide (PEO) nanofibers (PEO/CD) with the ultimate goal to develop functional nanowebs. Three different types of CDs; a-CD, b-CD and c-CD are incorporated individually in electrospun PEO nanofibers. The aqueous solutions containing different amount of PEO (3%, 3.5% and 4% (w/v...
