Effectof cellulose nanowhiskers (CNW) on crystallization kinetics of semicrystalline Poly(3- hydroxybutyrate-co-3-hydroxyvalerate)

摘要

It has been shown that nanoparticles can alter crystallization characteristics of semicrystalline polymers and consequently change morphology and properties of final nanocomposites. In this study, biodegradable polyester Poly(3-hydroxybutyrate-cd-3-hydroxyvalerate) (PHBV) films with 1.2-4.6 wt% of cellulose nanowhiskers (CNW) were manufactured by solution casting method using N,N-dimethylformide (DMF) as a solvent. Aqueous suspension of CNW was prepared by sulfuric acid hydrolysis. CNW was re-dispersed in DMF by solvent exchange method.
