Influence of the Polymer Content in the Preparation of Polymeric Membranes

Abstract:

This work aims to evaluate the effect of polymer content in the preparation of membranes obtained from polyamide 6/national clay nanocomposites. The polymeric membranes were produced varying the polymer content at 20 and 22% and using the technique of precipitation by immersion, which consists of three main steps: preparation a homogeneous polymer solution, scattering the solution on a surface forming a film of determined thickness and finally formation of polymeric structure of membrane by separation phases the system. The obtained results by scanning electron microscopy (SEM) indicated that the content of polymer changes the pore formation, the distribution and density, thereby obtaining membranes with different pore sizes, and it was possible to observe that the higher the polymer content, the lower will the pore diameter and more thicker will be the selective membrane layer.
