Figure S1.Comparison of ITO substrates before and after modification by chloroform. Before modification, when the ITO substrate approached the P3HT pillar film’s reverse side (a, b), the film was pushed away (c). After modification, when the ITO substrate approached the P3HT pillar film’s reverse side (d, e), the film was attached to the substrate (f). (PDF 1718 kb)
