From: Colorful Hydrophobic Poly(Vinyl Butyral)/Cationic Dye Fibrous Membranes via a Colored Solution Electrospinning Process

Fig. 1

Schematic illustrations of the colored solution electrospinning (CSE) process to prepare colorful nanofiber membranes (a). In this process, cationic dyes were added into pre-formed PVB solutions and dissolved in the solutions by vigorous stirring and then cationic dye colored PVB solutions can be e-spun into colorful nanofibers and collected as colorful nanofibrous membranes (NFMs). Molecular structure of PVB (b), cationic red dye (X-GRL) (c), cationic yellow dye (X-10GFF) (d), and cationic blue dye (X-GB) (e)
