Abstract
Embodiments of the present disclosure generally relate to processes for forming functionalized membranes. In an embodiment, a process for forming a functionalized porous membrane is provided. The process includes introducing a porous membrane with an aqueous solution of a hydrophilic agent in a reaction zone, and operating the reaction zone under conditions to form the functionalized porous membrane, the conditions comprising heating the reaction zone to a temperature of about 95° C. or less.
Claims20
A process for forming a functionalized porous membrane, comprising:
- introducing a porous membrane with an aqueous solution of a hydrophilic agent in a reaction zone, the porous membrane comprising aluminum-containing materials, titanium-containing materials, zirconium-containing materials, or combinations thereof, and the hydrophilic agent comprising a hydrophilic carboxylic acid or ion thereof;
- and
- operating the reaction zone under conditions to form a functionalized porous membrane, the conditions comprising heating the reaction zone to a temperature of about 95° C. or less.
A process for forming a functionalized ceramic membrane, comprising:
- combining a ceramic membrane and a hydrophilic agent solution in a vessel, the hydrophilic agent solution having a concentration of a hydrophilic agent of about 0.6 mol/L or more;
- reducing a pressure of the vessel for a duration of time effective to remove air from the vessel;
- and
- heating the vessel at a temperature from about 80° C. to about 95° C. to form the functionalized ceramic membrane.
A process for forming a functionalized ceramic membrane, comprising:
- combining a ceramic membrane and a hydrophilic agent solution in a reactor, the hydrophilic agent solution having a concentration of a hydrophilic agent of about 0.5 mol/L to about 0.7 mol/L;
- reducing a pressure of the reactor for a duration of time effective to at least partially remove air from the reactor;
- and
- reacting the ceramic membrane and the hydrophilic agent at a temperature below about 100° C. and for a time of less than about 19 h to form the functionalized ceramic membrane.
