Abstract In this study, hydrophilic polyurethane (PU) was synthesized by one shot process to get good non-swelling effect
and to keep high breathability using reactive silicone oil of mono terminal and bi-terminal types. We also blended non
reactive silicone oil with pure hydrophilic PU to compare non-swelling effect and breathability with hydrophilic PU
synthesized by the two types of reactive silicone oils. The hydrophilic films were analyzed by nuclear magnetic resonance
(NMR) spectroscopy, scanning electron microscope (SEM), Fourier transform infrared (FT-IR) spectroscopy, X-ray photo
electron (XPS) spectroscopy, energy dispersive spectrometry (EDS), breathability, waterproofness, tensile strength, contact
angle and swelling effect. The results showed that the film made by hydrophilic PU which was synthesized with mono
terminal type silicone oil provided good non-swelling effect and acceptable moisture permeability due to the modified surface
properties. |
