“…Some efforts have been carried out to enhance the thermal stability, the mechanical property of cellulose, by blending polymer in recent years. Hou et al 17 fabricated cellulose acetate (CA)/polyethylenimine (PEI) composite nanofibers via the electrospinning technique, and the result showed that the thermal stability was improved. Recently, Coimbra et al 18 prepared polycaprolactone (PCL)/gelatin methacryloyl (gelatin-MA) fibers by co-electrospinning and found that the mechanical property of PCL/gelatin-MA was enhanced.…”

In this paper, we report on the fabrication and characterization of cellulose/polyacrylonitrile (cellulose/PAN) nanofiber via the electrospinning technique. The effects of voltage and blending ratio on the morphology of the electrospun cellulose/PAN nanofibers are investigated. The electric field distribution of the nanofiber manufacturing system is simulated by using finite element method analysis. The results show that the morphology and diameters of the nanofiber are obviously affected with the change of the electric field and blending ratio. The surface morphology, chemical structural, thermal stability, mechanical property and wettability of the cellulose/PAN nanofibers with different blending ratios are evaluated systematically. The thermal stability and mechanical property of the cellulose/PAN nanofibers have a certain improvement compared with pure cellulose nanofiber. The wettability of cellulose/PAN nanofibers is better than that of ordinary medical gauze.

“…There is a wide range of endothermic peak results from moisture evaporation in PAN/PEI nanofibers. 34 The glass-transition temperature of PAN/PEI nanofibers is lower than that of PAN nanofibers. The introduction of PEI reduces the pure PAN crystallinity, resulting in the decrease of its glass-transition temperature.…”

The color of textiles plays a crucial role in meeting humans’ aesthetics needs and pleasure. Nanofiber has potential application prospects in textile and apparel due to its superior properties, such as the high specific surface area and porosity. Simultaneously, the coloring property has attracted widespread attention. However, the dyeing of polyacrylonitrile (PAN) nanofibers with reactive dyes remains a challenge due to the lack of reactive groups. Herein, an efficient strategy is proposed to successfully color electrospun PAN nanofibers with CI Reactive Red 2, enabled by introducing polyethyleneimine (PEI). Firstly, through entangling the molecular chain of PEI in solution, PAN is endowed with abundant cationic groups. Then, PAN/PEI nanofibers were obtained by electrospinning technology and further dyed using the reactive dye. More specifically, the different dyeing parameters, such as dyeing time, temperature, concentration and PEI concentration, were optimized. Compared to pure PAN nanofiber, PAN/PEI nanofiber achieved a higher dye uptake (96%) and better color fastness. This work offers an energy-saving and simple manner for improving the dyeing performance of PAN nanofibers using reactive dye.

“…A close inspection of PCL matsspectra showed that the presence of a small band close to 3439 cm -1 , attributed to O-H stretching vibration and the 1726 cm -1 peak exhibits a small shoulder located at 1708 cm -1 , which can be associated with COOH groups [36]. The spectra shows characteristic absorption peaks of PEI at 1580 and 1460 cm -1 [37], in the linear PEI, the amide group I peak is at 1648 cm -1 , and 1552 cm -1 corresponds with the amide II peaks [38]. The branched PEI shows it characteristic absorption bands at about 3440 and 1654 cm -1 assigned to the stretching vibration of the group -NH 2 [38].…”

In this study, we present a potential alternate approach for the treatment of melanoma skin cancer and skin tissue regeneration, a comparison of polycaprolactone (PCL) and polycaprolactone blended with linear (LPEI) and branched polyethylenimine (BPEI). This research presents the biocompatibility and feasibility of PCL, PCL loaded with LPEI and PCL loaded with BPEI in different concentrations, producing electrospun scaffolds. SEM images show that the nanofibers developed between 74 ± 419 nm. Contact angle assay demonstrated high hydrophobicity for all mats, which could be overcome by surface modification, namely, plasma treatment, ameliorating the hydrophilicity of the mats, providing excellent cells adhesion to the scaffolds surface. We demonstrate the biocompatibility of the scaffolds developed by electrospinning techniques, followed by in vitro tests with Human Dermal Fibroblasts (HDFs) and murine melanoma cells (B16), by using MTT assay to determinate the biocompatibility with all cells, and confocal images to give as insights of cell morphology (nucleus and cellular membrane). Sirius red collagen assay was performed for HDFs to give the collagen release profile after 6 days of incubation, and the possibility of the mats to help in skin regeneration process by forming extra cellular matrix (ECM). The CFMDA dye suggested no cytotoxicity for HDFs to monitor the morphology of live cells. The results have shown that all the scaffolds developed have good cell adhesion and proliferation properties. We could also observe high cytotoxicity for B16 melanoma cells for PCL_BPEI nanofibers. This primary in vitro study suggests that the mats developed may increase the skin regeneration process and at the same time promote apoptosis of melanoma cells, therefore it can be an emerging technology for skin regeneration, wound healing process and treatment of melanoma through electrospun drugs delivery system.
