Superfine Particles (SP) of soluble eggshell membrane and medical grade polyurethane (MPU) blend nanofibers were prepared by electrospinning different blend ratios of SP/MPU suspensions for regeneration of the natural fiber-like structure of the eggshell membrane. The addition of SP had no obvious effect on the electrospinning process of MPU nanofibers, and the SP were randomly dispersed in the...

In this study, research will be carried out to identify the functional group behavior of glassy and rubbery polymeric blend membrane with amines. Polymeric blend membranes with different blending ratios were prepared and the developed membranes were characterized by FTIR to see the effect of blend ratio on different functional groups. The developed membranes are flat dense sheet membrane of 20%...

Blend reverse osmosis membranes were fabricated using polyvinyl chloride (PVC) with cellulose acetate (CA) as polymer blends. Tetrahydrofuran (THF) and N-Methyl-2-pyrrolidone (NMP) were used as solvents. The membrane polymer solution was cast on a coated woven fabric support material. The prepared membranes have been characterized by SEM and mechanical properties. SEM r...

Abstract Background In this work, an economic study for production reverse osmosis (RO) membrane from a blend of polyvinylchloride (PVC) with cellulose acetate (CA) was investigated. The model predicting RO performance developed based on laboratory experimental data. conducted to investigate the feasibility producing polyvinylchloride/cellulose (PVC/CA) using large-scale batch casting machine a...

Membranes were prepared from alkaline lignin and poly(vinyl alcohol) (PVA) by a film casting method, and their properties were evaluated. These blend membranes can aptly be termed as green by nature as they are totally non-toxic and eco-friendly. The optimal mass ratio was determined based on the mechanical properties of membranes. The microstructure, mechanical properties, oxygen and carbon di...

Poly(p-phenylene terephtalamide) (PPTA), a high-performance polymer with high modulus and good hydrophilicity, is often used as a reinforced material. However, due to its high crystallity, micro-phase separation often occurs in the blends. In this paper, PPTA/poly(vinylidene fluoride) (PVDF) compatible blend solution was synthesized by in situ polycondensation. Blend ultra-filtration membrane w...

In this study, a nonsolvent thermally-induced phase separation (NTIPS) method was first proposed to fabricate hydrophilically-modified poly(vinylidene fluoride) (PVDF) membranes to overcome the drawbacks of conventional thermally-induced phase separation (TIPS) and nonsolvent-induced phase separation (NIPS) methods. Hydrophilically-modified PVDF membranes were successfully prepared by blending ...

In this study, ion exchange nanocomposite membranes was prepared by addition of Mg(OH)2 nanoparticles to a blend containing sulfonated polyphenylene oxide and sulfonated polyvinylchloride via a simple casting method. Magnesium hydroxide nanoparticles were synthesized via a facile sono-chemical reaction and were selected as filler additive in fabrication of ion exchange nanocomposite membranes. ...

an innovative method based on the membrane bioreactor (mbr) technology was developed as a potential remedy for the water shortage. mbrs attracted much attention in the field of wastewater treatment and reuse. it is reported from many researchers that membrane bioreactor technology is feasible and an efficient method for the treatment of wastewater. however, mbrs are faced to membrane fouling whic...
