Solvent casting and particulate leaching
open-in-new
<p>In solvent casting and particulate leaching (SCPL), a <a href="/facts/Polymer/eF32E50K">polymer</a> is dissolved in an <a href="/facts/Solvent/LoMPMz8S">organic solvent</a>. Particles, mainly salts, with specific dimensions are then added to the solution. The mixture is shaped into its final geometry. For example, it can be cast onto a glass plate to produce a <a href="/facts/Artificial_membrane/ImpnK6eH">membrane</a> or in a three-dimensional mold to produce a <a href="/facts/Scaffold/XB7qk4rd">scaffold</a>. When the solvent evaporates, it creates a structure of <a href="/facts/Composite_material/UBysQldh">composite material</a> consisting of the particles together with the polymer. The composite material is then placed in a bath which dissolves the particles, leaving behind a <a href="/facts/Porous/UoyAJU8X">porous</a> structure. </p>
