Definitions
- This invention relates to a manufacturing method of composite
- reacting agent material(hereinafter referred to as "reacting agent") over its surface and in its
- hydrophilic polymer is thinly coated over the surface of hydrophobic support
- the membrane should be essential to enhance the permeation rate
- the support membrane should simply support the non-porous active
- support membrane In general, main examples of support membrane include asymmetric
- ultrafiltration membranes including commercially marketable hydrophobic
- J hydrophilic polymer layer due to their lump induced by poor wettability but if the thickness of J hydrophilic polymer layer is larger, smaller permeation rate of permeating
- hydrophilic support membrane may be easily carried out based on
- support membranes include cellulose acetate and polyacrylonitrile [Germany
- hydrophilic support membrane has to meet the mechanical, thermal and chemical-resisting properties as an adequate support
- hydrophobic support membrane is to be made.
- an object of this invention is to
- the composite membrane of this invention has
- polymer on the membrane may be easily made, b) the affinity between
- hydrophobic support membrane and hydrophilic polymer may be enhanced
- the reacting agent infiltrates into the pores present at
- the reacting agent may be evenly dispersed
- the reacting agent may
- hydrophobic support According to this invention, preferred examples of hydrophobic support
- membrane include polysulfone- or polyetherimide-based ultrafiltration membrane in consideration of price and mechanical property.
- hydrophobic support membrane available shapes include a flat
- the swelling agent can be removed in such a manner that the
- hvdrophobic support membrane is dipped in an aqueous solution containing
- the reacting agent is placed at the surface and inside the
- hydrophobic support membrane where the swelling agent is removed.
- hydrophilic polymer used for this invention Since the hydrophilic polymer used for this invention has to meet
- polymer including the aforementioned polymers may have the same effects.
- reacting agents used for this invention include
- hydrochloric acid may be used; if chitosan is employed as hydrophilic polymer,
- sulfuric acid may be used; if polyvinyl is employed as hydrophilic polymer,
- glutalaldehyde may be used.
- the hydrophobic support membrane with no
- a desired infiltration may be achieved within 5-10 minutes.
- the hydrophobic support membrane is immersed in an aqueous
- hydrophilic polymer in aqueous solution is adjusted to 0.1-1%; if the concentration is less than 0.1%, the
- hydrophilic membrane cannot be coated on the hydrophobic support
- coating thickness of coating layer of hydrophilic membrane is
- the thickness is adjusted in the
- the support membrane is dried in the air and if deemed necessary,
- additional reaction may be performed in an oven at high temperature.
- a polysulfone ultrafiltration membrane was immersed in a mixture
- osmosis was carried out using an anion-based emulsifier in aqueous solution.
- the above table 1 showed the coating thickness and permeation property
- ultrafiltration membrane was immersed in each of sodium alginate in aqueous
- osmosis was carried out using an anion-based emulsifier in aqueous solution.
- osmosis was carried out using an anion-based emulsifier in aqueous solution.
- the membrane was dried in the air and further cross-linked at 100 ° C for 10
- osmosis was carried out using an anion-based emulsifier in aqueous solution.
- chitosan is a typical cationic polymer, anionic solute was adhered to the surface
- the composite membrane was prepared by coating each polymer on the membrane.
- ultrafiltration membrane was immersed in an aqueous solution containing
- thickness of coating membrane was higher than that of the latter, while the
- this invention has several advantages in that a) the
- composite membrane having a hydrophilic coating layer on a hydrophobic
- support membrane may be prepared based on the chemical reaction between a
- hydrophilic polymer a coating polymer; b) the thickness of coating layer may
