“…As a result, these mats are found suitable for biomedical applications as tissue engineering scaffolding, wound dressing, artificial blood vessels, drug delivery carriers, cosmetic and skin masks [6][7][8][9][10]. Recently, several researchers have reported electrospinning of several biocompatible polymers to explore their use in various biomedical applications These include polycaprolactone (PCL), polylactic acid (PLA), poly vinyl alcohol (PVA), chitosan, polyhydroxybuyrate and its copolymers [11][12][13][14][15][16][17][18][19]. However, there is very little information focusing on electrospinning of Nylon 11.…”

Abstract. Nylon 11 nanofibers mats were successfully prepared by electrospinning process from formic acid solution. The scanning electron microscopy (SEM) images showed that nanofibers with uniform diameter were produced when the polymer concentration was 10% w/v, whereas ribbons were formed at a higher concentration. The crystalline structure of the nanofibers mats was investigated using X-ray diffraction (XRD) and it was found that the nanofibers mats crystallized in γ form. The melt crystallized as well as solution casted films however exhibited α form. The thermal properties of these samples were studied using differential scanning calorimetry (DSC) and it was observed that electrospun fibers showed higher crystallinity than the melt-crystallized samples. However, the crystallinity of electrospun fibers was lower than the solution-crystallized sample.

“…Electrospinning precursor solution was prepared using the organic solvents CHCl3 and DMF (8:2 ratio) [47], containing 5 ml of 3% (w/v) of P3HB-co-12 mol% HHx and 15 microL of GAg. Precursor solution was subjected to magnetic stirring for 48 hours at room temperature followed by 2 hours heat treatment at 55 0 C to dissolve PHA completely.…”

Many wounds are unresponsive to current available treatment techniques and therefore there is an immense need to explore suitable materials including biomaterials, which are being considered as the crucial factor to accelerate the healing cascade. In this study, we fabricated polyhydroxyalkanoate based antibacterial mats via electrospun technique. One-pot green synthesized graphene decorated silver nanoparticles (GAg) were incorporated into the fibres of poly-3 hydroxybutarate-co-12 mol% hydroxyhexanoate (P3HB-co-12mol% HHx), a co-polymer of polyhydroxyalkanoate (PHA) family which is highly biocompatible, biodegradable and flexible in nature. The synthesised PHA/GAg biomaterial was characterized by field emission scanning electron microscopy (FESEM), elemental mapping, thermogravimetric analysis (TGA), UV-visible spectroscopy (UV-vis) and Fourier transform infrared spectroscopy (FTIR). In-vitro antibacterial analysis were performed to investigate the efficacy of PHA/GAg against gram positive Staphylococcus aureus (S.aureus) strain 12600 ATCC and gram negative Escherichia coli (E.coli) strain 8739 ATCC. The results indicated that the PHA/GAg demonstrated significant reduction of Staphylococcus aureus (S.aureus strain 12600 ATCC) and Escherichia coli (E.coli strain 8739 ATCC) as compared to bare PHA or PHA-rGO in 2 hours of time. The P value (P< 0.05) was obtained by using 2 sample T-test distribution.

“…Additionally, polymer solution properties such as viscosity, conductivity and surface tension also affect fiber morphology [16,17]. In general, the size of the nanofibers decreases with decrease in the concentration of the polymer solution, increase in the applied voltage, and increase in the distance between the electrodes [18,19].…”
