“…Zeolite-polymer composites have been developed for some use including separation of gaseous molecules [3][4][5][6][7][8], honeycomb zeolite sheets [9], ultrafiltration membranes [10], catalysis system [11], bone tissue engineering [7], and so on. Types of this application are based on their porous character and ion exchange properties.…”

Abstract. This review focuses on the latest reports of the use of zeolites, natural as well as synthetic, as biomedical materials. Discussion on biocompatibility, non-toxicity, zeolite for drug delivery materials, zeolite for bone implants and implant coatings, and the mechanical properties of polymer-zeolite composites are included. The section on the interaction between body tissues and zeolite-based biomaterials focuses on their biocompatibility, non-toxicity, and bioactivity. The next section concerns drug delivering biomaterials. Including delivery of a controlled drug, ionic removal, and synthesized drug delivering materials. The final section concern bone graft substitutes and implant-coating to improve corrosion resistance and osteointegration. The implant material system discussed in a further section is an investigation of the mechanical properties of high-density polyethylene(HDPE)-zeolite composites developed as skull bone implant materials.

“…The increase in pervaporation flux with increasing operating temperatures could be explained by the enhanced average kinetic energy of the molecules and faster molecular motion at higher temperatures, as described by the Arrhenius relationship [22]. Mass transfer coefficient of components in the liquid and sorption of components into the membrane could also increase with increasing feed temperature.…”

Abstract. Pervaporation, a membrane-based technique, is taken into consideration in order to separate water from biodiesel-methanol mixtures. Several operational conditions in biodiesel production could cause water contamination into the reaction mixture, which can affect biodiesel production and quality. In this study, bacterial cellulose-alginate (BCA) nanocomposite film was applied as a selective membrane in order to separate water from biodiesel-methanol mixtures using pervaporation. For effective operation, factors that affected the performance in the pervaporation, such as concentration of water in the biodiesel-methanol mixtures and temperature of the process were investigated. It was demonstrated that, the BCA membrane has good potential for removing water from the biodiesel-methanol mixtures. Under a permeate pressure of 10 mmHg and 30 °C, the BCA membrane could separate water from the mixture containing methyl ester (C10:0): methanol: water at a weight ratio of 42.3: 52.7: 5 with a total permeate flux of 148 g/(m 2 h) and a water selectivity of 332. The permeate was contained 94.5% w/w water and methyl ester was completely rejected by the BCA membrane. The increase of water concentration in biodiesel-methanol mixtures and the temperature rise resulted in an increase in the permeate flux but lowered the selectivity.

“…Zeolites are well known as porous materials, and several have proton conducting properties [8,9]. PVA is well known as a water-soluble polymer, and many studies on zeolite-PVA composite films have been reported for various applications [10][11][12][13][14][15], and most of these studies utilized an aldehyde cross-linking reaction in acidic condition (Figure 2) [15,16]. Cross-linking of PVA can be carried out in thin film form, which is very important in this study, since the PVA can easily be cross-linked by penetration of the cross-linker aqueous solution after composite film preparation.…”

Abstract. In this study, organic-inorganic composite electrolyte membranes are developed for a novel water-absorbing porous electrolyte water electrolysis cell. As the materials of the composite electrolyte membrane, 80 wt% of a proton-conducting nano zeolite (H-MFI) as an electrolyte and 20 wt% of poly(vinyl alcohol) (PVA) as a cross-linkable matrix are used. The nano zeolite is prepared by a milling process. The nano zeolite-PVA composite membrane precursors are prepared by spraying onto a substrate, followed by cross-linking. The resulting nano zeolite-cross-linked PVA composite films are then evaluated for their properties such as proton conductivity as electrolyte membranes for the water-absorbing porous electrolyte water electrolysis cell. It is confirmed that conventional materials such as zeolites and PVA can be used for the water electrolysis as an electrolyte.
