Key Points

The study aims to develop polyamines that overcome the limitations of traditional polyesters in medical applications by enhancing degradation rates and mechanical properties.
Developed poly(p-dioxanone)/polycaprolactone/polyethylene glycol (PPDO/PCL/PEG) based amphiphilic polyurethanes.
Evaluated mechanical retention and degradation rates under simulated physiological conditions.
Conducted in vitro assessments to measure the performance of the new polymer formulations.
The developed amphiphilic polyurethanes exhibited significantly improved degradation rates compared to conventional polyesters (p<0.05).
Mechanical retention was enhanced, maintaining structural integrity for longer periods in simulated environments.
In vitro tests demonstrated superior biocompatibility and performance of PPDO/PCL/PEG over traditional options.

Abstract

Polyester-based biodegradable polymers are widely used in absorbable medical devices, however, the hydrophobic essence of polyesters limits the implanted applications in the conditions required rapid degradation. This work reported poly(p-dioxanone)...
