Novel graphite-filled PVA/CS hybrid membrane for pervaporation of benzene/cyclohexane mixtures

Proton conducting membranes prepared by incorporation of organophosphorus acids into alcohol barrier polymers for direct methanol fuel cells

“…6. For the pure PVA/CS membrane without GA crosslinking, the characteristic crystalline peaks at 11.6 • , 18.3 • , 23.7 • and 26.5 • which were attributable to CS [28] and the peaks around 20 • which was attributable to PVA could be clearly observed [29]. The major crystalline peak of CS at 11.6 • was remarkably weakened after incorporation of HDTMP and completely disappeared after GA-crosslinking treatment, while another major peak at 18.3 • was also diminished.…”

Novel ultrafiltration membranes prepared from a multi-walled carbon nanotubes/polymer composite

“…Hybrid membrane incorporating both organic and inorganic components is a convenient and efficient approach to avoid the tradeoff effect [4]. Inorganic materials, such as zeolite, graphite, and silica, have been used to improve the performances of polymeric membranes [5][6][7]. Carbon nanotubes (CNTs) attracted considerable attention from both academia and industry due to their excellent mechanical, electrical, and thermal properties [8][9][10].…”

Pervaporation dehydration of isopropanol using homogeneous polyelectrolyte complex membranes of poly(diallyldimethylammonium chloride)/sodium carboxymethyl cellulose

“…Pervaporation is one of the representative membrane-based techniques for separating liquid mixtures [2,3]. Application of pervaporation includes separating organics from water [4,5], separation of organic-organic mixtures [6,7] and dehydration of organics [8,9]. Among these applications, dehydration of organics is probably the most known and developed.…”
