Abstract:This study explores the interplay between elastomeric
nanofibrillar
thermoplastic polyurethane (TPU) and cellulose nanocrystals (CNCs)
to expand the applications of poly(lactic acid) (PLA) composites via
optimization of the nanofibril TPU/CNC ratio. Advanced analytical
methods reveal the contrasting effects of CNC stiffening and TPU toughening
capabilities. Fourier transform infrared spectroscopy (FTIR) and nuclear
magnetic resonance (NMR) confirm isophorone diisocyanate (IPDI) as
a cross-linker and chain exte… Show more
