Figure 4.3 Reversible switching of the wettability of a P4VP brush-modified ETFE surface. The sample was immersed in 0.1 M HCl or H2O prior to contact angle determination, and the process was repeated several times to demonstrate the reversibility of the change in contact angle. The resulting water CAs differed by 36. Source Adapted from Neuhaus et al. [2], with permission from John Wiley Sons Inc.

The spray head configuration is an interesting aspect of EHDA. The nozzle varies from a simple hypodermic needle of different diameters to highly technologically advanced multiplex nozzles (Figure 22.8). The coaxial needle shown increases the number of centered nozzles to four and is mainly used to fabricate multilayer spheres. In coaxial setups, the most commonly used is the coaxial two-capillary nozzle used to fabricate core-shell spheres (capsules). The inner needle is supplied by a solution of active substance and the outer needle is filled with shell material.In this process, parameters are used as adjusting switches to control the diameter of the capsules, thickness of the shell, and number of inner cores. The two solvents used in the coaxial setup are immiscible and wettable, and the inner one has a higher surface tension. [Pg.417]
