Abstract
The synthesis of waterborne polyurethane cationomers was successfully carried out. Different proportions of α,ω-di(hydroxyl)polydimethylsiloxane (PDMS) modifier (0–7.3% by weight) were applied. Analysis of IR spectra confirmed the structure of obtained polyurethane cationomers and the incorporation of a modifier into the polyurethane structure. The differential scanning calorimetry (DSC) method was employed for the microstructural assessment of the obtained materials. A clear decrease of the degradation temperature with increasing amounts of incorporated PDMS indicates immiscibility part of the polysiloxane segments with soft segments derived from polyethylene glycol. Changes were discussed in the free surface energy and its components, as calculated independently according to the method suggested by Owens–Wendt, in relation to chemical and physical structures of cationomers as well as morphology of coating surfaces obtained from those cationomers. Test results of contact angle measurements indicated that with increasing content of the polysiloxane in the analyzed films, the contact angles increase. Copyright © 2017 John Wiley & Sons, Ltd.
