Electrospun membranes appear to be increasingly popular for water treatment applications. I under how they are fabricated, etc but Im not quite how they are used, I would be grateful if someone could answer the below questions:
1) Electrospun mats as spun appear like white flexible sheets. Are these used as is? or do they need to be place on a supporting surface?
2) In some papers I've seen the electrospun membrane being placed on nonwoven polyester substrates, im not quite sure why this is done?
Thanks,
