Electrostatic spraying (ESS) has found applications in many areas, including agriculture, ink-jet printing, thin film coating, nanotechnology, etc. Flow-limited field-injection electrostatic spraying (FFESS) is an advanced and unique ESS technology because it has many advantages over the conventional electrostatic spraying (CESS). FFESS is not only able to generate more stable and reproducible spraying at lower voltages, but also to spray insulating liquids. What is more, FFESS can generate stable and controllable multi-jet spraying, which leads to many new applications. This book will...
