Details of solution preparation for electrospinning and spin-coating of poly(methyl methacrylate) (PMMA) including—molecular weight (Mw), concentration w/w (C), solvents, and the rotation speed of stirrer (Vr); the electrospinning parameters—voltage (U), distance needle to collector (d), flow rate (Q), and humidity (H), used to produce PMMA scaffolds with nanofibers, microfibers, and ribbons.
