โฆ Synopsis
The influence of incorporated silver on the properties of polyurethane based on poly(tetramethylene glycol) 1010, methylenebis( p-cyclohexyl isocyanate), and butanediol was investigated. The influence of the incorporated metal ions was reflected in the form of a reduction in the stress-strain parameters as well as an alteration in the thermal behavior. The water uptake of the material was increased severalfold by the incorporation of the silver ions. The induced hydrophilicity together with the variation in mechanical and thermal properties was assigned to the considerable alteration in the morphological features of the polyurethane that resulted from the incorporation of silver ions.
