The patterned fluoropolymer film hydrophobicity and colored oil layer uniformity were critical for electrofluidic displays. Typically, reactive ion etching (RIE) is commonly used to pattern fluoropolymer films due to the chemically inert nature of fluorinated materials. However, the RIE process permanently changed the surface properties of the fluoropolymer film. These affect the function of the electrofluidic displays. The development of inkjet printing technology provides an innovative manufacturing pathway for functional materials, such as fluoropolymers. In this work, for the first time, an amorphous fluoropolymer (AF 1600) was patterned by a piezoelectric inkjet printer as a hydrophobic layer for an electrofluidic display. The pattered fluoropolymer films can be inkjet printed by varying the concentration of the fluoropolymer solution and adjusting printing parameters. Phase change filing was explored in combination with inkjet printing of colored oil, enabling the manufact...
