Polymeric Membranes for Purification

Self-assembly of the diblock copolymer can be utilized as a template for producing polymeric membranes. Current research aims to pave the path for producing membranes of desired pore sizes using the same precursor method.

Steps for analyzing phase diagram of diblock copolymer-water-oil system

Behavior of Complex Fluids

Small particles dispersed in a solvent can interact via hydrodynamic and inter-particle interactions. Inter-particle interactions arise due to electrostatic repulsion, Van der Waals attraction, steric repulsion, or depletion interactions. Overall, the behavior of suspension depends on the strength, range of forces, and thermal fluctuations.

Schematic of polymer adsorption on laponite discs

Laponite and PVA chains are represented by circular disc and red coils, respectively. The left side to right side of the diagrams in each sub-regime shows an increase in the concentration of polymer in suspension
