Application of cryogenic grinding for filler preparation in the form of Coconut Nanocomposites into the Thermoplastic Matrix with the evaluation of properties while using different types of MAgPP Coupling agents / Petr Lenfeld...[et al.]

The application of natural plant materials as fillers in polymeric materials is currently a very interesting area of research in order to achieve specific properties of polymer composites with a potential of the particular application in various industrial fields. One of these areas is the research concerning cryogenic grinding application for the preparation of nanoparticles from natural materials and the use of such prepared fillers in polymer matrices of a synthetic or natural origin. This paper focuses on the implementation of nanoparticles produced by cryogenic grinding of natural coconut fibers into a polypropylene matrix, evaluating the effects of different types of MAgPP coupling agents providing sufficient wettability and therefore compatibility at the interface between the hydrophobic polymer matrix and natural fillers, on final properties of polymeric nanocomposites

Properties of Injection Molded Nanocomposites and Blends Based on PLA, PHBV and L-CNC / Martin Borůvka...[et al.]

The practical approach to produce sustainable, biobased, biodegradable and ecofriendly blends and nanocomposites with tailored material properties is reported in this paper. The aim of study is to investigate the effect of blending and addition of heterogeneous nucleating agents based on lignin-coated cellulose nanocrystals (L-CNCs) on the properties of poly(lactic acid) (PLA) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) blends and nanocomposites. The crystallization behaviour, morphology, impact strength and heat deflection temperature of neat PLA, blends and nanocomposites were investigated. Masterbatches were prepared by melt mixing using an internal mixer and further then were standard tensile test bars injection molded. The results showed that both property modifiers (PHBV and L-CNC) had significant influence on PLA material properties. Crystallinity of resulted samples has been improved. Morphology examinations showed PHBV well dispersed in PLA phase in form of droplet like particles in nanometre range. An increase of impact strength and heat deflection temperature (HDT) has been observed
