Resumen:
To perform a material with potential biomedicals
aplications, a novel gelatin films was prepared by
cold-casting method using cerium (III) and genipin
solution as crosslinking agents, and surface modified
with dendritic molecules. The structure and properties
of the synthesized gelatin films were investigated by
ATR-FTIR, mechanicals tests, swelling behavior and
water vapor permeability (WVP). The results showed
that crosslinking could improve the mechanical
properties and lower the hydrophilic property of the
gelatin films; additionally, the system
gelatin/cerium(III)/genipin film showed the best
properties, so was prepared a one-surface modified
film with weysocianate (commercial dendron) from
this. The results showed that experimental
methodology performed allows the one-surface
modification, so was obtained a novel biomaterial as
film form with good properties and dendritic structure
in one face (hydrophobic and hydrophilic faces) that
gives a multivalent structure useful in biomedicine
development.
