Investigating the effect of adding polyethylene glycol (PEG) on thewettability properties of thermoplastic polyurethane

In this study, thermoplastic polyurethanes containing the soft segment (polyol polyester) and the hardsegment (methylene diphenyl diisocyanate and ۱, ۴-butane diol) were synthesized by prepolymerizationmethod. Polyethylene glycol ۴۰۰ was added to the hard segment of polyurethaneduring synthesis until the wettability properties of polyurethane increase. In order to investigate thechemical structure and physical properties of the synthesized polymers, FTIR and Tensile analyseswere used. The water contact angle and water absorption content of polymers were investigated. Theresults showed by increasing the amount of polyethylene glycol in thermoplastic polyurethane, theamount of water absorption increased and the amount of water contact angle decreased
