Plasma-graft filling polymerization: preparation of a new type of pervaporation membrane for organic liquid mixtures

Grafting of Polyelectrolyte on Porous Substrate by Plasma-induced Polymerization

“…Additive here means 10 wt% sodium chloride (NaCl), lithium chloride (LiCl) or sodium dodecyl sulfate (SDS). The plasma-induced graft polymerization technique developed in our previous work [7] was employed. Briefly, a HDPE substrate was treated with argon plasma at a pressure of 10 Pa, and then was exposed to air for 1 minute.…”

“…1) can provide favorable feature onto the materials. Namely, compared with the methods using high energy radiation such as electron-beam or X-ray, PIGP can activate only the outer surface and inner pore surface of porous substrate [7], in other words, the technique has little negative effect on the mechanical properties of the substrate.…”

Development of Pore-filled Ion-exchange Membranes for Efficient All Vanadium Redox Flow Batteries

“…15,16) The PFMs composed of a chemically inert and mechanically tough porous substrate and a polymer with ion-exchange groups (i.e. ionomers) that fills the pores can provide both high ion conductivity and excellent mechanical properties.…”

Development of thin film composite for CO2 separation in membrane gas absorption application

“…[8] Other than that, the preparation of TFC by (1) the plasma-graft filling polymerization was investigated using a porous high-density polyethylene films and poly(methyl acrylate), (2) photograft composite membrane was investigated using asymmetric polyacrylonitrile membranes and hydrophilic(meth)acrylates, and (3)Co 60 radiation induced graft polymerization was investigated using porous ethylene films and acrylic acid were wisely discussed for pervaporation and gas separation process. [9,10,11] The objective of the present work was to investigate TFC membrane formation based on glutaraldehyde (a simple cross-linking agent). The TFC membrane preparation parameters (support type and porosity, coating characteristics, etc.)…”
