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.

“…Figure 19. A proposed microstructural model: (a) Uniform sized and nanoscale dispersion of zeolite nanoparticles in dope solution lead to small size nodules formation and result in small pore size with high pore density; (b) an agglomerate of zeolite nanoparticles in dope solution lead to large size nodules formation and result in large pore size with reduced pore density [103].…”

Morphology Control of Polysulfone Membranes in Filtration Processes: a Critical Review

et al. 2015

Polysulfone (PSU) membranes have been widely applied in microfiltration and ultrafiltration processes due to their excellent properties, such as chemical inertness across the entire pH range, compressive strength, and thermal stability. Despite these advantages, the application of PSU membranes in filtration processes has often been restricted due to their hydrophobic nature, which results in serious membrane fouling and a reduced permeate flux. Moreover, PSU membranes suffer from several disadvantages, including bulky structure, low binding force between fibers, and poor mechanical properties. The key factor in the development and application of polymeric membranes is the control of its polymeric morphology due to the significant influence of membrane morphology on the membrane performance. Effective techniques of controlling PSU membrane morphology are accessed, and the effects of the morphological control on mechanical properties, chemical stability, membrane performance, and membrane fouling are investigated. Findings from various individual studies were analyzed and discussed in order to provide a critical review of this subject. The results emphasized that the membrane pore size and surface porosity mostly governs PSU membrane morphology, which enhances membrane performance and reduces membrane fouling.

“…However, based on the elastic modulus values as shown in Table 3 which is determined from the slope of the initial linear portion of the stress vs strain curve, F4 has higher elastic modulus (113.78 MPa) as compared to F3 (48.82 MPa). Elastic modulus represents the stiffness of hybrid membrane, which is resistance to elastic strain [10] and further confirmed through lower elongation that is attributed to the reduction in the ductility of the membrane as stated by Dahe et al [11]. The needs for good ductility of membrane is important to ensure easy manufacturing of membrane where it will not easily crack and can be easily molded into the required shape.…”

“…The needs for good ductility of membrane is important to ensure easy manufacturing of membrane where it will not easily crack and can be easily molded into the required shape. As described by Zubir and Ismail [10], in the production of PTFE (Polytetrafluoroethylene) membrane, the targeted outcomes were membranes with high tensile strength and strain but with low elastic modulus for easy shaping of the membrane into a thin membrane with a uniform thickness.…”

Thin Film Composite Membranes: Mechanical and Antifouling Properties

et al. 2017

Abstract. As compared to membranes produced from pure polymer or pure inorganic materials, a hybrid membrane possesses better mechanical and thermal properties. This paper reported on the effect of incorporating silica nano-precursor (tetraethylorthosilicate) as well as glycerol in the formulation of hybrid membrane on the mechanical properties and antifouling properties of the resultant thin film composite membranes. The mechanical properties were measured in terms of tensile strength, tensile strain and elastic modulus. Whereas for antifouling properties, it was evaluated through the measurements of relative flux decay (RFD) and relative flux recovery (RFR), along with the permeate flux rate, percentage glycerol permeated and NaCl rejection. Results showed that the presence of silica and glycerol in hybrid membrane's formulation had increased the tensile strength and elongation of the resultant membranes. In addition to that, the incorporation of glycerol has resulted in thin film composite with better antifouling properties as compared to the thin film composite with barrier layer from the pure polymer blend. Based on its performance, the fabricated thin film composite has a great potential to be used as a pathway for crude glycerol purification due to some advantages over the existing process that employ membrane.
