Autophobic dewetting of polymer melts was characterized by well-defined polystyrene (PS) melt droplets that dewetted chemically identical brushes upon thermal annealing. The contact angle (θ) of PS droplets on the brushes and interfacial tension (γm/b) between the PS melts and brushes significantly increased as the chain length of PS brushes decreased and grafting density increased. The super autophobicity of the PS melt at the extremely short and dense PS brush was evaluated when the γm/b increasingly converges on the maximum interfacial tension (γ*m/b).
