Is polyacrylonitrile hydrophobic or hydrophilic?

<h2>Why Polyacrylonitrile (PAN) is Changing Membrane Technology</h2> <p>When designing advanced filtration systems, material choice is everything. A key player in this field is <strong>polyacrylonitrile (PAN)</strong>, a polymer widely known for its excellent <strong>hydrophilicity</strong>. Unlike hydrophobic materials that tend to repel water and trap contaminants, PAN’s affinity for water allows fluids to pass through efficiently while maintaining high performance.</p> <p>Beyond its water-loving nature, PAN brings exceptional <strong>chemical and solvent stability</strong> to the table. These traits make it an ideal support layer for thin-film composite (TFC) membranes. Because it can withstand harsh environments without degrading, engineers can push filtration boundaries further.</p> <p>Ultimately, the unique properties of PAN unlock new possibilities in demanding separation tasks, including <strong>forward osmosis</strong> and <strong>organic solvent nanofiltration</strong>. By bridging the gap between durability and permeability, PAN continues to be a go-to material for modern industrial and environmental filtration challenges.</p>
