in order to improve the flexibility of poly (DL-lactide) (PDLLA)
a high molecular weight poly(dioxanone) (PPDO) with great flexibility was added in PDLLA matrix with different weight ratios.Hybrids were characterized in terms of phase structure (scanning electron microscopy)
thermal properties(differential canning calorimetry and dynamic mechanical analysis)
mechanical properties(tensile analysis)
surface properties(dynamic contact angle analysis) and degradability.As a result of the PPDO appended in
the flexibility of the PDLLA was significantly improved as well as the degradation speed of the blends.
