Abstract
A membrane composite includes at least two 3D-printed layers extending in an x-y plane and including a first plurality of interlaced strands forming a first plurality of interstitial spaces defined by first inner surfaces of the interlaced strands, and a polymeric coating coated on a surface of the at least two 3D-printed layers and on the first inner surfaces of the first plurality of interstitial spaces to form pores, wherein the polymeric coating is adapted for wastewater filtration. A method of producing the membrane composite.
Claims15
A membrane composite comprising:
- at least two 3D-printed layers extending in an x-y plane and comprising a first plurality of interlaced strands forming a first plurality of interstitial spaces defined by first inner surfaces of the interlaced strands;
- and
- a polymeric coating coated on a surface of the at least two 3D-printed layers and on the first inner surfaces of the first plurality of interstitial spaces to form pores,
- wherein the polymeric coating is adapted for wastewater filtration.
A method of producing a membrane composite, the method comprising
- a first step of 3D printing a 3D-printed structure, wherein the 3D-printed structure comprises at least two layers comprising a first plurality of interlaced strands forming a first plurality of interstitial spaces defined by first inner surfaces of the interlaced strands;
- and
- a second step of coating a surface of the 3D-printed structure and the first inner surfaces of the first plurality of interstitial spaces with a polymeric coating solution and allowing the polymeric coating solution to form a polymeric coating comprising a plurality of pores, wherein the polymeric coating is adapted for wastewater filtration.
