Resumen:
Biocompatible polymers like polycaprolactone (PCL)
and polyvinylalcohol (PVA) have several interesting properties that make them
very interesting for biomedical applications; nevertheless many of them depend
of the processing method. In the case of wound dressing, the
incorporation of nancoclays into PCL improves mainly the barrier and
mechanical properties. This enhancement is strongly related with the clay
dispersion degree. The properties of PVA cryogels mostly depends on the crosslinking and crystallinity degree. On the other hand, it is still unclear the role
that processing variables, such as the numbers of freezing/thawing (F/T)
cycles, the cycle extent, the freezing temperature, , the polymer concentration
and its molecular weight (Mw) play on
the significant properties of the
material.
The aim of this work was to analyze the effect
of processing variables on the improvement of specific properties of of
PCL-clay and PVA-hydrogel to be used as wound healing.
