Abstract

Procedimiento para la preparación de membranas de carbono. A partir de polvo de grafito y materiales poliméricos (resina fenólica y una poliimida), y sobre un soporte de carbono poroso formado por aglomeración y carbonización de mezclas conformadas de grafito y resina fenólica, se deposita una fina película de disolución de ácido poliámico, el cual tras su imidación se convierte en una película de poliimida la cual una vez carbonizada a vacío se transforma en una fina película continua de carbono microporoso perfectamente adherida al soporte.
