Abstract
The invention relates to a method for producing a multi-capillary lining comprising a plurality of channels suitable for convection of a fluid between an inlet face and an outlet face of said lining, said method comprising the steps of: —providing at least one preform (1) suitable for forming, after ablation, a capillary channel (3) of the lining; —assembling said preforms into a bundle; —coating each preform (1) with a plurality of porous layers (2) by depositing alternating layers of a polyelectrolyte and nanoparticles or colloidal nanoparticles or by depositing alternating layers of said nanoparticles and a polymer glue; —bonding the coated preforms to form a porous monolith; and—ablating the preforms to form the channels in said porous monolith.

A method for producing a multi-capillary packing comprising a plurality of channels suitable for convection of a fluid between an inlet face and an outlet face of said packing, said method comprising:
- providing a plurality of preforms suitable for forming, after ablation, a respective capillary channel of the packing;
- assembling said plurality of preforms into a bundle;
- coating each preform with a plurality of porous layers by depositing alternating layers of a polyelectrolyte and nanoparticles or colloidal nanoparticles,
- bonding the plurality of coated preforms to form a porous monolith;
- and
- ablating the plurality of preforms to form the channels in said porous monolith.
