Web12 aug. 2024 · The hydrophilic and hydrophobic characters of the grafted polymer brushes were evaluated by the determination of contact angles values (Θ). Droplets (2 μL) of polar (water, formamide) and nonpolar (diiodomethane) liquids were put on the layer of grafted polymers. WebWe reported hydrophilic polymer brushes formed at the interface between water and hydrophobic polymer matrix by the segregation of amphiphilic diblock copolymers blended in the matrix. In this system, while the hydrophilic block with high surface energy avoids air surface, it segregates to cover the interface between hydrophobic PDMS and water.
