Abstract

Un método para preparar una placa hidrofóbica que comprende las fases de recubrir una placa con una solución de dispersión que incluye resina hidrofóbica, y secar dicha placa recubierto, apto para reducir la presión interna de una célula, aumentado de este modo la duración de la célula. Además, un método de inmersión utilizando una dispersión que puede preparar fácilmente una placa hidrofóbica, si lo comparamos con un método de rociado con polvo. Asimismo, de este modo no se produce polvo lo que facilita la preparación de una placa hidrofóbica y puede controlarse fácilmente la cantidad de resina a base de flúor que recubre la placa controlando la concentración de la solución acuosa de la dispersión.
