Static Self-Adsorption of Polyelectrolytes onto the Membrane Surface

3 Static Self-Adsorption of Polyelectrolytes onto the Membrane Surface 

Static deposition is a process where the deposition of polyelectrolytes onto the membrane support is done without any external force to make the polyelectrolyte solution flow through or stay on the membrane support. This also implies that the static deposition method is more inexpensive and easier to be broadly applied in membrane surface modification because less energy is required to complete the modification or fabrication process. Most of the membrane fabrication or modification employing
