Biodegradable Open Cell Foams of Telechelic Poly(ε-caprolactone) Macroligand with Ruthenium (II) Chromophoric Subunits via Sub-Critical CO2 Processing

This work reports on the effect of CO2 at subcritical conditions and the gaseous state on the telechelic poly(epsilon-caprolactone) polymers. The tested polymers are semi-crystalline in nature and thus the effect of functional groups and their overall contribution to foaming and formation of microstructures with open-cell morphollogy is discussed.
