Preparation of semipermeable polycarbonate membranes and study their chemical physical and mechanical properties and one of its application

Abstract EN

Now polycarbonate (PC) used to make semipermeable membranes by the phase inversion process, this way is a primary way to get flat membranes.

In the experimental part of this work, four membrane samples were made with different casting parameters (polymer concentration in the casting solution) were tested for chemical properties (chlorine tolerance and pH rang) and physical properties (viscosity, pore size and porosity) and mechanical properties (tensile strength and strain).

The results showed that PC (10%, 12%) membrane having the higher chlorine tolerance and pH rang, on the other hand membrane (PC 12%) having the higher viscosity, tensile strength and strain but it was having the lowest pore size and porosity.

One of the membrane application was the determination of average molecular weight for any polymer, so we determined the polystyrene (PS) molecular weight by knowing its osmotic pressure
