Dip coating of microemulsions on hollow fibres for improved membrane filtration performance: An industrial perspective?
Laboratoire de Génie Chimique, Université de Toulouse, CNRS, INPT, UPS, Toulouse, France
Membrane filtration performances can be enhanced by the deposition of a selective thin layer on the surface of a porous substrate. Our simulation focus on the deposition of nanometric bicontinuous microemulsions onto hollow-fibre membranes and its polymerisation using UV modules. To that end, the laws governing the deposition of linear liquids have been extended to the study of the deposition of microemulsions. Our simulation highlights the difficulty of depositing a thin liquid coating on the fibre without causing its capillary penetration into the porosity of the substrate, due to the very low surface tension of microemulsions.
