Variable Responsive Wettability Films via Electrospinning Induced by Solvents

Figure 2

Typical SEM images of PNIPAAm/PS composite films which were fabricated from PNIPAAm/PS/solvents (2 : 10 : 90 w/w/w). (a), (b), and (c) correspond to films IV, V, and VI in which the solvent of the precursor solution is DMF, CH₂Cl₂, and THF, respectively.
