**Solvent System** &
\begin{tabular}{c} **PCL/Filler** \\ **Nanecomposites** \\ \end{tabular} & **Mechanical Properties and Observations** & **Refs.** \\ \hline Acetic acid/dimethylsulphoxide & PCL/Chitosan & Young’s modulus shows a favourable increase of about 215.5 MPa, which is in analogous range with the tendon rigidity at the acceptable ligament regeneration load of 250 MPa. & [72] \\ \hline Chloroform & PCL/Graphene/Nanotube & There is a significant increase of the Young’s modulus with the incorporation of graphene/nanotube at 0.5\% and 1\% because of the uniform dispersion of the PCL fiber. & [86] \\ \hline Dimethylformamide & PCL/Cellulose nanofibers & Elongation at break and the tensile strength increase with increasing the cellulose nanofibers content, reaching the maximum at 1\%, after which it decreases with further increase at 5\% due to the self-agglomeration of the aggregates at higher concentration by virtue of hydrophobicity of the matrix. & [87] \\ \hline Acetic acid & PCL/F127 & [PERSON]’s modulus of Ejected scaffold, hierarchical scaffold and TIPS PLLC show a comparable values of 6.1 MPa \(\pm\) 0.8, 6.6 MPa \(\pm\) 0.2 and 6.67 MPa, respectively. Accordingly, the ultimate tensile strength displayed 0.7 MPa \(\pm\) 0.3, 0.5 MPa \(\pm\) 0.1 and 1.8 MPa \(\pm\) 0.3. & [82] \\ \hline Acetic acid/formic acid & PCL & Elastic modulus is of pristine PCL and the plasma treated PCL remain unchanged at 6 MPa. & [88] \\ \hline Acetic acid/formic acid & PCL/Gelatin & Loss modulus increased with the addition of gelatin into the PCL because of the weak interaction and poor affinity between two components of the nanocomposites. & [89] \\ \hline Melt electrospinningning & PCL/LATC30 & Loss and storage moduli increase with the incorporation of LAT30 into the PCL matrix due to the long relaxation time and improved elasticity, which control the movement of polymer chains in the blend mats. & [80] \\ \hline Chloroform/methanol & PCL/PCS/Gelatin & Elongation at break increases from 36.8 MPa \(\pm\) 4 to 102.0 & \\ Chloroform/methanol & PCL/PCS/Gelatin & 1.61 MPa \(\pm\) 0.1 for wet and dry conditions accordingly. The elastic modulus displays a decrease by nearly 81\% from dry to wet medium. The introduction of less rigid gelatin accounts for the modulus strength close to intrinsic myocardium. & [84] \\ \hline Hexafluoroisopropanol & PCL/PLGA/Tenofovir & The tensile strength and Young’s modulus showed infinitesimal changes with the addition of tendovir. The incorporation of tendovir has insignificant effect on the general mechanical properties of the electrospun PCL/PLGA blend. & [85] \\ \hline \hline \end{tabular}

Table 4: _Cont._solvents issues, such as biocompatibility and suffocating smell, should be taken in consideration. It is advised that the process of electrospinningine be appropriately conducted in well-ventilated fume-hoods with excellent operational conditions, and the temperature should be adequately considered.
