Enhancing the Solubility of Semiconducting Polymers in Eco
WebYou can see for yourself with polymer chains (from 1 to 10) floating in a virtual (invisible) sea of solvent molecules. The key variable is RelAttr, the relative attraction of the solvent for the polymer. When this is large (--> 1) the polymer prefers, on average, to be surrounded by the sea of solvent molecules so tends to be fully extended. WebSep 5, 2024 · According to the Kamlet-Abraham-Taft (KAT) polarity parameters (α, β, π*), polymers and solvents can be categorized as hydrogen-bond (H-bond) acidic (α>β) or H-bond basic (α WebPolymers and Packaging. Determining the diffusion rate of solvent molecules through a polymer is vital in polymer processing, analysis, and performance. Another characterization that can be studied is the solubility parameter which is directly related to the cohesive energy density of a material. how many metro lines in hangzhou
