Line 4. Fabrication and modification of synthetic membranes
The objective of this line of research is the manufacture and modification of porous synthetic membranes for ultrafiltration, microfiltration and other processes.
The manufacturing is carried out from polymer and/or plastic collodions that may subsequently be susceptible to modification, with the aim of producing low-fouling membranes and at the same time improving their permeoselective properties, through the addition of nanoparticles and/or surface activation.
The use of recycled polymers for the manufacture of membranes, compared to the use of commercial polymer, offers an alternative for the manufacture of low-cost membranes. These membranes could currently be competitive according to their characterization parameters, compared to the commercial membranes themselves.
After the manufacture of the different membranes, equipment is available for the characterization of their structure using both laboratory techniques (Porosity, Equilibrium water content, Average pore radius and Ternary phase diagram), and microscopic techniques (Scanning Electron microscopy), Thermogravimetric Analysis and Contact Angle).
In addition, laboratory plants are available at different scales for the application of all membrane techniques and for the characterization and feasibility study of the manufactured and/or modified membranes.
