Inhibiting Oil Overflow in Electrowetting Display through Selectively Hydrophilic Modification of the Pixel Wall Based on Polydopamine and Polydopamine/Polyvinylpyrrolidone via Regional Protection Strategy

Advanced Materials Interfaces, Volume 10, Issue 32, November 14, 2023., 2023
A method is developed through selectively hydrophilic modification of the pixel wall based on sole polydopamine (PDA) and polydopamine/polyvinylpyrrolidone (PVP) hybride layer, respectively. The static contact angle decreases from 75.4° to 48.8° for PDA modified surface and 29.2° for PDA/PVP surface, producing a larger wettability gradient between the ...
