article description
The controlling of mechanical properties of hydrogel by crystallization of hydrophobic domains, were investigated. Two chemically equivalent polymer systems were compared, in which only the stereochemistry is changed to create amorphous vs semicrystalline hydrogels. The stiffness of hydrogels made from PLA-PEO-PLA can be controlled by the stereoregularity of the polymer. The results show that the use of PLA allows the stereochemistry to be altered while holding all other molecular parameters constant and thus allowing the impact of crystallinity ton be determined directly.
