Publication number: 20210197128Abstract: A method for healing a damaged separation membrane for water treatment uses silica microparticles surface-functionalized with polyethyleneimine. The method can be applied to actual water treatment processes because the particle size and chemical stability of the silica microparticles surface-functionalized with polyethyleneimine are maintained under various operation conditions are used. A separation membrane for water treatment healed exhibits superior healing performance, with water permeability and rejection rate being healed to 90% or higher as compared to the pristine separation membrane, and maintains physical and chemical stability for a long time. Moreover, the method is advantageous in that flux does not declines after the healing because the silica microparticles surface-functionalized with polyethyleneimine are selectively deposited on the damaged part. In addition, it is advantageous in terms of economy in that silica microparticles commercially available at low cost are used.Type: ApplicationFiled: December 26, 2017Publication date: July 1, 2021Applicants: YALE UNIVERSITY, KOLON GLOBAL CORPORATIONInventors: Bezawit GETACHEW, Sang-ryoung KIM, Jae-hong KIM, Seung-joon KIM, Seong-kyun YIM, Moon-sun KANG

Patent number: 10618012Abstract: A method for manufacturing a self-healing hydrogel-filled separation membrane for water treatment includes soaking a porous support comprising pores in a monomer solution to fill the pores with the solution, removing the excessively filled monomer solution from the porous support, and forming a hydrogel in the pores by crosslinking the monomer. The separation membrane does not require an additional repair process when damage occurs to the separation membrane and can exhibit superior self-healing effect and physical stability.Type: GrantFiled: December 21, 2016Date of Patent: April 14, 2020Assignees: YALE UNIVERSITY, KOLON GLOBAL CORPORATIONInventors: Bezawit Asheber Getachew, Sang-ryoung Kim, Jae-hong Kim, Seung-joon Kim, Seong-kyun Yim, Moon-sun Kang
