A Kinetic Framework for the Pyrolysis of Poly(Ether‐Ketone‐Ketone) (PEKK)
Journal of Applied Polymer Science, EarlyView.Crosslinking influences poly(ether‐ether‐ketone) (PEKK) pyrolysis. ABSTRACT Research to date on the thermal degradation of poly(ether‐ketone‐ketone) (PEKK) has largely been limited to low temperatures or analysis as part of a composite. Herein, we investigate the pyrolysis kinetics of neat PEKK from 480°C to 1000°C and characterize the degradation by ...

Journal of Applied Polymer Science, EarlyView.Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...
