Özet
In this study, a blend solution of hydroxypropyl-β-cyclodextrin (HPβCD) and benzoxazine monomer (BA-a) was prepared in dimethylformamide to obtain HPβCD/BA-a microfibers by electrospinning technique. The electrospun HPβCD/BA-a microfibers were then thermally cured to obtain crosslinked PolyHPβCD/PolyBA-a microfibers. The compositions of HPβCD (120%, w/v) and BA-a (25%, w/v) were determined as an optimum concentration for producing bead-free and uniform microfibers from blend of HPβCD and BA-a (HPβCD/BA-a). Afterwards, the HPβCD/BA-a microfibers were thermally cured using step-wise curing method to obtain water-insoluble crosslinked PolyHPβCD/PolyBA-a fibrous membrane (FM). However, the fibrous structure of PolyHPβCD/PolyBA-a membrane was subjected to some morphological deformation during thermal curing. Therefore, citric acid (CTR, 5% and 15%, w/v) was …
