New Polyurethane Biocomposites Based on Cellulosic Fibers: Effect of the Cellulose Content on the Composite Thermomechanical Properties
Two polyurethane (PU) matrices were synthesized using poly(ε‐caprolactone) diol and 4,4′‐diisocyanato dicyclohexylmethane using two different synthetic approaches. NMR and FTIR spectroscopy analysis ensured the chemical structure and the formation of the matrices. Thereafter, composite materials were prepared by in...
