“…Recent studies clearly indicate that organic polymers are more suitable starting materials for the industrial grade membrane synthesis due to their ease of fabrication and remarkable properties [5]. These organic polymers include polysulfone [6,7], polyethersulfone [8][9][10], polyvinylidene fluoride [11,12] and cellulose acetate [13,14].…”

Polyethersulfone -barium chloride blend ultrafiltration membranes for dye removal studies Rambabu K, Srivatsan N, and Anand V P Gurumoorthy Department of Chemical Engineering, School of Civil and Chemical Engineering, Centre for BioMaterials , Cellular and Molecular Theranautics, VIT University, Vellore -632014, Tamil Nadu, India.Email: rambabu.k@vit.ac.in Abstract.A series of Polyethersulfone (PES) -barium chloride (BaCl 2 ) blend ultra filtration membrane was developed by varying the BaCl 2 concentration in the dope solution. Prepared membranes were subjected to membrane characterization and their performance was studied through dye rejection tests. Morphological studies through SEM and AFM showed that the composite membranes exhibited differences in morphologies, porosities and properties due to the BaCl 2 addition as compared with pristine PES membrane. Addition of the inorganic modifier enhanced the hydrophilicity and water permeability of the blend membrane system. Polymer enhanced ultrafiltration of dye solutions showed that the proposed blend system had better performance in terms of flux and rejection efficiency than the pure polymer membrane. The performance of the 2 wt% BaCl 2 blend membrane was more promising for application to real time dye wastewater studies.

“…There are four types of methods for functional surface construction, including surface-coating [13,14], surface-grafting [15][16][17][18][19], copolymer directly formation [20][21][22], and blending [6,7,[23][24][25][26][27]. Surface coating is an efficient and easy-to-operate method that directly covers a functional layer onto the membrane surface by physical adsorption interaction.…”

“…It appears that the pore sizes in the membrane active-layer decrease progressively from the upper surface towards the inner section. Progressive decrease of these pore sizes and good performances of these membranes for ultrafiltration of heavy metal ions, published previously [11], suggest the high membrane tortuosity from one face to another.…”

“…As a result, it was found that, the membrane properties depended on: (i) uniform distribution of PAA chains in the network formed by the PSf matrix, (ii) rate of immobilization of PAA, and (iii) morphology of the membrane. The PSf/ PAA membrane has shown good performances for the ultrafiltration of different heavy metal solutions and dye molecules [10,11]. Here, our interest will be focused on the PSf/PAA membrane morphology in order to learn much about the mechanisms of the morphology forming and to know how to improve the membrane performances in view to prepare tailored membranes.…”

Experiment Polymer propertiesPolysulfone (PSf) and poly (acrylic acid) (PAA) were supplied by Aldrich and dimethyl formamide (DMF) by Prolabo. All polymers and chemical products were used as supplied, without any further purification. Molecular weights of PAA and PSf were 450 000 and 26 000 g/mol, respectively. Membrane preparationPolysulfone (PSf) and Poly (acrylic acid) (PAA) were dissolved, separately, in dimethyl formamide (DMF) in a glass reactor equipped with a mechanical stirrer and thermostated at 90°C for over 3 hours. The PSf concentration was 17 (or 19) wt. % and that of PAA was 5 wt. %. Afterwards, both solutions were mixed together in known proportions, stirred for 30 min and de-bubbled. Such de-bubbled casting-solution was casted on a glass plate with a lab-made Gardner knife, dried in freeair for a known time (generally 20 seconds) and finally immersed in a coagulation-bath containing a sufficient volume of MilliQ water (18.2 MΩcm) at 18°C. Membranes were thoroughly washed with water, and stored in a dilute sodium azide solution till their use. Kinetic measurementFive polymer-solutions with the same mass (2 g) and different composition (PSf/PAA 100/0, 96/04, 92/08, 89/11 and 83/17) were poured on a glass plate to get exactly a same surface area. Afterwards, AbstractThis work focuses on the study of the morphology forming of Polysulfone (PSf) and polyacrylic acid (PAA) membranes which are prepared by mixing both of the polymers in DMF and the obtained blend is precipitated in water (non-solvent). The precipitation kinetic and the effects of polysulfone concentration, drying-time in free-air and proportions of both polymers are investigated.Based on the SEM technique, the kinetic and viscosity measurements, and the visual observations, this study brings to the fore the different steps of the morphology forming of PSf/PAA membranes: formation of finger-like structures, sponge-like-structures, inner pores, superficial pores and the craters. Appearance of these structures is governed by the exchange process, between casting polymer-solution and the precipitation-bath (coagulation), which is controlled by operating conditions. This work constitutes a great tool in understanding the mechanisms of the morphology forming of PSf/PAA membranes and to improve their performances: preparation of tailored membrane.
