“…The most common solvent mixtures used are chloroform:methanol, chloroform:ethanol, and dichloromethane (DCM):methanol at 90:10, 80:20, and 70:30 solvent ratios, respectively, for electrospinning of PBSu/food-grade agents [ 15 ]; DCM/N, N-dimethylformamide (DMF) at a ratio of 1:9 to obtain PLA/graphene oxide (GO)/quercetin (Q) electrospun scaffolds [ 162 ]; and DCM/DMF (7:3, v / v ) and 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP)/ethanol (7:3, v / v ) for preparing encapsulated antimicrobial agents in PLA/PEO/PVP matrices [ 16 ]. The addition of acetic acid to the mixture of chloroform:ethanol to dissolve the PLCL/PCL copolymer prevented the formation of beads, and led to fibers with diameters in the range of 200 nm to 2.8 µm [ 163 ]. There were also reported nanofibers with diameters of 1.68 ± 0.58 µm and 1.51 ± 0.64 µm in the case of electrospun PLA/HPO [ 21 ], 1.107–1.243 µm in the case of PLA/GO/Q [ 162 ], and 1.9 ± 0.5 μm in the case of PHB/PCL modified with hybrid melanin–TiO 2 nanostructures [ 18 ], which are considered as adequate for cell adhesion and attachment.…”
