Resumen:
Hydrogels consist on a hydrophilic soft polymer, which forms a three-dimensional network and has the ability to absorb a large amount of water. In particular, cryogels of polyvinylalcohol (PVA) constitute an eco-friendly alternative because they can be obtained by a physical crosslinking method thus avoiding the use of potentially harmful components. However, the use of hydrogels sometimes is restricted due to their specific properties. PVA-bentonite nanocomposite hydrogels have been prepared and chemically, morphologically and mechanically analyzed. Specifically, in the present work, thermal degradation behavior of PVA-bentonite hydrogels will be studied. Kinetic analytical models will be applied to non-isothermal thermogravimetric measurements.
