This article provides a comprehensive review of the principles, mechanisms, materials, and applications of interfacial polymerization in membrane synthesis.

Principles of Interfacial Polymerization

Interfacial polymerization operates on the fundamental concept where two monomers, each soluble in different phases, react at the interface to form a polymer. This polymerization typically happens at the interface between a water phase and an organic phase. The distinctive inherent properties such as density, solute diffusivity, and reactivity of the reactants govern the structure and hence the functionality of the resulting membrane.

Key Components:

1. Phase Separation: Typically involves an aqueous phase and an organic phase. Choice of solvents critically influences the formation and properties of the membrane.
2. Reactants: Monomers in each phase react to form a polymer at the interface. Commonly used monomers include polyamines and polyacyl chlorides.
3. Catalysts/Initiators: Sometimes involved to initiate or accelerate the polymerization process.

Mechanism of Interfacial Polymerization

The typical process involves the immersion of a porous support in an aqueous monomer solution (e.g., diamine), followed by the contact with an organic phase containing another monomer (e.g., acid chloride). At the interface, these monomers react quickly to form a polymeric film. The key steps in the mechanism include:

1. Diffusion: The monomers from each phase diffuse to the interface.
2. Reaction: At the interface, monomers react to form the polymer.
3. Growth: The polymer film grows at the interface, becoming a barrier to further diffusion of reactants.

Principles of Capacitive Deionization

To understand HCDI, it’s essential first to grasp the basics of Capacitive Deionization (CDI). CDI is an electrochemical water treatment technology that removes ions from water through electrostatic adsorption onto porous electrodes. This process involves applying a low voltage across the electrodes, causing cations and anions within the feed water to migrate towards the oppositely charged electrodes, where they are held, effectively de-ionizing the water.

The Basic CDI Cycle

1. Charging Phase: During this phase, a potential difference is applied between two electrodes (usually made of activated carbon or other porous materials). Positively charged ions (cations) in the water migrate towards the negatively charged electrode, while negatively charged ions (anions) migrate towards the positively charged electrode.
2. Desorption/Discharge Phase: Once the electrodes become saturated with ions, the applied voltage is reduced to zero or reversed, allowing the ions to be released back into a waste stream. This cyclical process ensures continuous purification of the feed water.

Advantages of CDI

• Energy Efficiency: CDI operates at lower voltages than methods like RO, translating into significant energy savings.
• Scalability: CDI units can be scaled up or down to meet varying water treatment demands.
• Lower Environmental Impact: CDI technology generally produces less waste and fewer harmful by-products than traditional techniques.
