Adhesion images of a w/o SEBS (PM6:Y6), b 30%-SEBS doping, c 50%-SEBS doping, and d SEBS-interface films were obtained by PFQNM method (thescanne d area is 2 μm × 2 μm). Elastic modulus images of e w/o SEBS, f 30%-SEBS doping, g 50%-SEBS doping, and h SEBS-interface films obtained by PFQ NM method (the scanned area is 2 μm × 2 μm). i Mechanism diagram of adhesion enhancement.
