Matsu To reduce membrane fouling of reverse osmosis (RO) membrane, we adopted layer-by-layer (LbL) assembly. LbL assembly has received attention as a means of preparing ultrathin layers of composite membrane...
متن کاملProtein and Lactose Separation by Modified Ultrafiltration Membrane using Layer by Layer Technique
Layer-by-Layer (LbL) is a method which can be used for nanoscale coating and surface functionalization of a material. LbL technique mainly uses the electrostatic attracting between charged materials (polyelectrolytes, nanoparticles, etc.) and an oppositely charged surface. In this study, protein separation (BSA) from lactose solution was carried out using the LbL self-assembly method, which was...
متن کاملNovel Membrane Materials for Reverse Osmosis Desalination
The use of solvents in desalination processes limits the use of certain materials in the construction of the reverse osmosis membranes. Therefore now the research effort has focused on improving new materials. In particular, nanostructured materials will probably form the basis for new reverse osmosis membrane materials. This study makes a review of the new materials used for the construction o...
متن کاملAutomated spin-assisted layer-by-layer assembly of nanocomposites.
We present the design and verification of a desktop system for the automated production of nanostructured thin films via spin-assisted layer-by-layer (spin-LBL) assembly. The utility of this system is demonstrated by fabricating polyvinyl alcohol/clay nanocomposites. Ellipsometry measurements demonstrate that the automated spin-LBL method creates composites with bilayer thickness and growth rat...
متن کاملCharge Inversion and Layer-by-Layer Assembly of Flexible Polyelectrolytes
We have applied a continuum self-consistent field (SCF) theory to flexible polyelectrolytes on flat surfaces which are either uncharged or carrying the opposite charge as the polyelectrolytes. We examined in detail the effects of various parameters on the polyelectrolyte adsorption and surface charge compensation by the adsorbed polyelectrolytes. The ground-state dominance approximation (GSDA) ...
