• hydrophobic surface of PS-enriched domains. The droplets are characterized by a relatively large wetting angle that indicates hydrophobicity of the underlying locations. Compared to surface potential studies the use of dC/dZ measurements was relatively limited by studies of organic layers [23] and water

• adsorption [24][25]. Recently, the situation has changed and there is now an increasing interest in nanoscale dielectric studies. Our interest in PS-PVAC blends was brought about by recent efforts to measure its local dielectric properties by different EFM approaches [17][19][20][26]. The static dielectric
