- Abstract
- Wool fibres were submitted to green hydrolysis with superheated water in a microwave reactor, in view
of potential valorisation of keratin-based wastes. The keratin hydrolysates containing free amino acids,
peptides and low molecular weight proteins, were exploited as a biofiller in preparing polypropylene
matrix composites. Maleic anhydride grafted polypropylene was used as a compatibilizer to promote
dispersion of keratin. The thermal and mechanical properties were investigated in dependence of keratin
and compatibilizer loadings, and related to morphological characteristics. The presence of keratin preserved
the molecular weight of the polymer matrix during the processing and gave good overall mechanical
properties to the compatibilized composites. The keratin hydrolysates strongly interfered on the
crystallization behaviour and thermo-oxidative degradation of the polypropylene. The increase of
polypropylene crystallization rate and the enhancement of thermal stability were observed as a function
of the keratin amount in the compatibilized composites. (literal)
