Study of Surface Tension of Binary Mixtures of Poly (Ethylene Glycol) in Water and Poly (Propylene Glycol) in Ethanol and Its Modeling Using Neural Network

In this work, the surface tension (σ ) of aqueous solutions of pegs (poly ethylene glycol) with molecular weights of 200, 300 and 6000 in water, and poly (propylene glycol) (ppg) with a molecular weight of 2000 in ethanol, were measured in the (293.2-338.2) k temperature range and atmospheric pressure. the results of the measurements were modeled by an artificial neural network(ann) with input of mass fraction of polymer and solution temperature. the predictions of the artificial neural network model fit the experimental data perfectly.
