Membrane separation is known as an efficient technique for the oily wastewater treatment. Therefore, in the present study, sulfonated poly (ether ether ketone) (SPEEK) was introduced into the polysulfone (PSF) solution in order to enhance the hydrophilicity and the membrane structure for the oil–water separation. The hollow fiber membranes were fabricated via a phase-inversion process. The memb...

in the present study, floating drug delivery beads (fdds) were prepared with sodium alginate/ starch blend as a matrix, sodium hydrogen carbonate as a pore forming agent, methyl cellulose as a binder and barium chloride solution as a hardening agent. in order to prepare the beads with different porosity and morphology the ratio between pore forming agent to polymer blend and ratio of the consti...

In this study, poly carbonate (PC) and poly (ethylene terephthalate) (PET) were reactive melt-blended under two different conditions to produce PC/PET copolymers. For each condition, samples were taken at specified mixing times representative a specific structure of copolymers and each one employed to physically compatibilize a PC/PET blend with a fixed composition. Reactive blending and copoly...

With the booming of automobiles industry, recycling automobile shredder residue (ASR) with complicated constitutes gradually become an urgent issues owing to its difficulty for traditional recycling. Herein, solid-state shear milling (S3M) technology which can control domain size various polymers in blend was applied overcome mismatch viscosity and poor compatibility ASR thus modify processabil...

Abstract Nowadays, greenhouse covering materials have a vital role in terms of protective cultivation process. Many farmers use polyfilms, rigid or semi-rigid plastic panels, and glazing as the present scenario. However, these are known for their high cost, short service life, cause harmful environment. Solar transmittance property is one main criteria choosing any materials. This study prepare...
