Biodegradable open cell foams of telechelic poly(epsilon-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.
