“…For a further study, we tested the effect of dye concentration on the value and σ K / S by taking cationic dye X-10GFF as an example. It has been reported that value shows a linear relation with increasing dye concentration [21]. As shown in Fig.…”

“…For coloring e-spun nanofibers, electrospinning-dyeing method is a useful and common process that electrospinning is firstly used to fabricate NFMs and then dyeing the e-spun NFMs by fixing the natural or synthetic dyes onto the NFMs, which can absorb and reflect light at specific wavelengths to give human eyes the sense of color [18–21, 23, 24]. However, the electrospinning-dyeing technique is complex and inefficient, especially for the NFMs with higher surface area and higher ability to scatter more light [19–21]. …”

Colorful nanofibrous membranes have attracted much attention for their visual varieties and various functionalities. In this article, a colored solution electrospinning process was used to fabricate colorful hydrophobic poly(vinyl butyral) (PVB)/cationic dye nanofibrous membranes (NFMs) successfully. The color and morphology of these as-spun nanofibrous membranes have been analyzed by colorimetry, spectroscopy, and scanning electron microscopy (SEM). It is shown that the as-spun colorful PVB-based membranes exhibit excellent level-dyeing property and color stability. Furthermore, the doping of cationic dye and the increase of dye concentration can decrease the diameter of the as-spun colored fibers, which results in better level-dyeing property and higher water contact angle more than 140°. The stained PVB fibrous membranes with excellent level-dyeing property and hydrophobicity are promising in some applications such as textiles, wallpapers, and anticorrosive coating/painting.Electronic supplementary materialThe online version of this article (doi:10.1186/s11671-016-1763-4) contains supplementary material, which is available to authorized users.

“…Additionally, the peak at 1738 cm -1 is assigned to the carbonyl band (C=O) of the acetate group in the CA nanofibers. [26][27][28] In the case of Zein/CA blends, the intensity of the CA related bands present at 1738, 1368, 1225, and 1036 cm -1 became weak and showed a slight shift to higher wavenumbers as the proportion of Zein component was increased in the blend. For instance, the carbonyl peak of CA was observed at 1750 cm -1 for the Zein/CA blend.…”

Protein based scaffolds are preferred for tissue engineering and other biomedical applications owing to their unique properties. Zein, a hydrophobic protein, is a promising natural biodegradable polymer. However, electrospun structures prepared from Zein have poor mechanical and wetting properties. Cellulose acetate (CA) is an economical, biodegradable polymer having good mechanical and water retention properties. The aim of present study was to fabricate a novel material by electrospinning Zein/CA blends. A series of Zein/CA hybrid nanofibers were electrospun and characterized. The attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) spectrum showed the characteristic peaks of both Zein and CA, and was composition dependent. The X-ray photoelectron spectrometry (XPS) curves of Zein/CA blends demonstrated a similar profile to that of pristine Zein nanofibers. Thermogravimetric analyser (TGA) studies confirmed that the Zein/CA hybrid nanofibers have a higher degradation temperature and better thermal stability than pristine Zein nanofibers. The glass transition temperature (T g ) of Zein/CA hybrid nanofibers was also increased in comparison to pure Zein nanofibers as revealed by differential scanning calorimetry (DSC). Zein/CA hybrid nanofibers have hydrophilic surface character as revealed by water contact angle (WCA) analysis. SEM imaging showed bead free morphology of the electrospun nanofibers. The average nanofiber diameter decreased for Zein/CA blends with increasing CA composition. The electrospun Zein/CA hybrid nanofibers may be used for tissue engineering scaffolds and for other biomedical materials.

“…Through amounts of intra-and inter-chain hydrogen bonds, the cellulose chains assemble into regularly arranged crystalline and pores filled with irregular amorphous chains [4][5][6][7][8][9]. A hierarchical porous structure formed during the assembly of cellulose chains into a cellulose material, which occupies a large volume of the cellulose material [5,10]. The hierarchical pores in cellulose material can accommodate liquid, which is the advantage of cellulose materials in the field of electrolyte reservoir, separation membranes, facial mask and scaffold for tissue engineering [11][12][13][14][15][16][17][18][19].…”
