About

PFSA Polymer Dispersions,Ion Exchange Resin Solution

Ion exchange resin is an insoluble polymer compound with functional groups (active groups that exchange ions), network structure. Pore structure is divided into gel type and macroporous type. Those with physical pore structure are called macroporous resin. If the classification is acidic, "cation" should be added before the name, and if the classification is alkaline, "anion" should be added before the name.
PFSA polymer dispersions are made from chemically stabilized perfluorosulfonic acid (PFSA) in the acid (H) form and are available in several polymer contents and dispersant compositions. Typical uses include the fabrication of thin films and coating formulations for fuel cell membranes, catalyst coating, sensors, and a variety of electrochemical applications.

Adsorption selection:

Ion exchange resins have different affinities for different ions in solution and are selective for their adsorption. There are general rules for the strength of various ions exchanged and adsorbed by resin. The main rules are as follows:
1, adsorption of cations
High-valence ions are usually preferentially adsorbed, and among the same-valent ions, the ions with larger diameters are more strongly adsorbed. Some cations are adsorbed in the following order:
Fe3+> Al3+> Pb2+> Ca2+> Mg2+> K+> Na+> H+
2, the adsorption of anions
The general order of adsorption of inorganic acid radicals by strongly basic anion resins is:
SO42-> NO3-> Cl-> HCO3-> OH-
The general order of adsorption of anions by weakly basic anion resins is as follows:
OH-> citrate-> SO42-> tartrate-> oxalate-> PO43-> NO2-> Cl-> CH3COO-> HCO3-
3, Adsorption of colored substances
Sugar liquid decolorization often uses strong basic anion resin, which has strong adsorption to pseudo-melanin (reducing sugar and amino acid reaction product) and alkaline decomposition products of reducing sugar, while the adsorption of caramel color is weak. This is thought to be due to the fact that the first two are usually negatively charged, while caramel has a weak charge.
Generally, resins with a high degree of crosslinking are more selective for ions, and resins with macroporous structures are less selective than gel-type resins. This selectivity is larger in dilute solutions and smaller in concentrated solutions.

1, A base titration procedure measures the equivalents of sulfonic acid in the polymer, and uses the measurement to calculate the acid capacity or equivalent weight of the pure polymer.
2, Thermogravimetric Analysis was performed to test the decomposition temperature. The polymer were placed inside a furnace and heated from room temperature to 600C at a heating rate of 10C/min.

Application:

1. As the material of the PFSA ion exchange membrane
SY-1000 perfluoro sulfonic acid ion exchange resin is used as the materials of ion exchange membrane, the fuel cell membrane, the ion exchange membrane for vanadium battery, the ion membrane for a chlor-alkali industry, the hollow fiber membrane, the super acid catalyst used in organic synthesis, the super stable ion exchanger, and the like are reprepared in various electrolysis apparatuses.
2. Fuel Cell Applications: PFSA polymer dispersion and PFSA resin solution is a diluted, liquid form of the same chemical used for a PEM fuel cell membrane, PFSA polymer dispersion, and PFSA resin solution can drastically reduce the amount of platinum needed as a catalyst by exposing a larger fraction of the platinum to the hydrogen gas. Also, PFSA polymer dispersion and PFSA resin solution act as a binding agents to hold the platinum, membrane, and gas diffusion layer together.

The ion exchange resin>

The bases of ion exchange resins mainly include styrene and acrylic acid (esters), which are polymerized with the cross-linking agent divinylbenzene respectively to form a polymer with a network skeleton structure with a long molecular main chain and a cross-linked transverse chain.

The degree of crosslinking of the resin, that is, the percentage of divinylbenzene used in the polymerization of the resin matrix, has a great influence on the properties of the resin.
