Abstract

Se provee una metodología para la producción de fibras finas electro-hiladas, para generar una cantidad significativa de fibras con diámetros de menos de 100 nanómetros. También se provee una composición mixta de medio de filtro que comprende una capa de substrato y una capa de fibras finas electro-hiladas, que tiene una eficiencia incrementada con respecto a la caída de presión y/o a una distribución controlada de tamaños de poro. De acuerdo con algunas modalidades, se electro-hila nylon a partir de una combinación de solventes de ácidos fórmico y acético.
