WebDec 15, 2007 · parameter Flory-Huggins theory. There is, however, no con-sensus on how to improve upon the Flory-Huggins theory. Measurements of ł for a chosen pair of polymers are typically made using one set of polymers, i.e., for a particular value of N1 and N2.13 There are relatively few cases where polymer blend thermodynamics are studied as a … The Flory-Huggins interaction parameter \(\chi\) for polymer-solvent mixtures captures the nature of interactions and provides insights on solubility. \(\chi\) is usually estimated using experimental or (empirical) computational methods, which may be expensive, time-consuming or inaccurate. See more For the dataset accumulated over various sources, dataset validation was done to ensure its viability. From the definition of \chi, it follows that the smaller the value of \chi, the greater is the reduction in Gibb’s free energy of … See more Next, we move on to discuss the trained GPR-based ML model utilizing the 1586 \chi data points corresponding to 58 polymers and 140 solvents, trained using 400 features. … See more One of the major goals of any machine learning algorithm is extrapolative prediction. Thus, there is a need to validate the model by checking its generalizability. To ensure the model’s validity, we tested … See more
