Özet
In this study, polyurethane films prepared from the 4,4-diphenylmethane diisocyanate (MDI), ethylene glycol, and different ratio fructose were used to prepare a novel amperometric pH electrode. Fructose-based films were characterized by FT-IR, DSC, DTA, and TGA. Prepared polyurethanes exhibited suitable T-g(degrees C), good thermal stability and good adhesive properties. The incorporation of saccharides into the PU structure results in a higher crosslinking density and a higher content of hard segments. Furthermore, the behavior of films prepared from polyurethane solutions containing 1%, 3%, 5%, and 10% fructose toward pH changes were examined by normal pulse voltammograms technique and diferantial pulse voltammetry.
