Influence of Hydrogen Bonding on the Temperature-Accelerated Hydrolysis of Silicone Based Polyetherurethane
degradation was established to estimate the longevity of polyurethane applied for long-term implantation. However
the prediction did not correlate well with the data from clinical explants and the rationality of accelerated
in vitro
test is still in a controversial due to the deviation. To improve the accuracy of the
in vitro
prediction
the influence of hydrogen bonding (HB) on the accelerated hydrolysis of silicone based polyetherurethans (SPEUs) extended with three side chains. Combining the temperature-controlled FTIR and the physical properties after temperature-accelerated
in vitro
degradation
it was demonstrated that side chain could increase the degree of hydrogen bond dissociation at higher temperature
resulting in the decrease of the calculated activation energy (
E
a
) of hydrolysis. At low temperatures
changes in surface morphology and molar mass of PEUs are minimal and HB are less easily dissociated
which had barely impact on the hydrolysis resistance. It was proposed that the
E
a
will not be impacted and that the accuracy of prediction will be increased if the acceleration temperature is lower than 70 °C and HB change is less than 15%.
