Název v původním jazyce

The effect of nucleating agents, blending and annealing on crystallization, impact properties and heat deflection temperature of PLA/PHBV/L-CNC bionanocomposites

Popis výsledku v původním jazyce

The production of renewable, biobased and biodegradable bionanocomposites is dicussed in current research. The developement of such materials is mainly driven by rising concerns over environmental issues, sustainability and dependency on decreasing petroleum resources. The effect of blending, addition of heterogeneous nucleating agents and post-molding annealing on properties of poly(lactic acid) (PLA), poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and lignin-coated cellulose nanocrystals (L-CNCs) bionanocomposites was investigated. Masterbatches were prepared by melt mixing using an internal mixer and further then were standard tensile test bars injection molded. The crystallization behaviour, morphology, impact strength and heat deflection temperature of neat and annealed PLA, PLA/PHBV blends and PLA/PHBV/L-CNC bionanocomposites were investigated. The results showed that both property modifiers (PHBV, L-CNC) and post-molding annealing had significant influence on material properties.
