“…The lower of tensile strength of composites are PVA-OPFB-20% and PVA-OPFB-5%. Tensile strength and elongation at break are improve due to the strong interaction between PVA and nanocellulose [6]. Increase nanocellulose in the matrix make the tensile strength decreased, it cause the possible aggregation of nanocellulose in the polymer matrix and also nanocellulose was not disperse homogeneously in the polymer matrix [14].…”

Composites polyvinyl alcohol filled with nanocellulose from oil palm empty fruit bunch (OPEFB) and oil palm fronds (OPF) have investigated. Nanocellulose prepared by formic acid 50 wt%. Functional groups and degree of crystalline of nanocellulose were analyzed by FTIR and XRD. The degree of crystalline nanocellulose presented at 2θ at intensity of 22.26 and 21.86 for OPEFB and OPF. Amorphous part of nanocellulose at intensity of 14.68 and 15.86 for OPEFB and OPF. Functional group of nanocellulose give the same pattern for OPEFB and OPF. Nanocellulose reinforce in polyvinyl alcohol as many as 1, 5, 10 and 20% and as a comparison with polyvinyl alcohol without filler. Eight of composite films and one of vinyl alcohol film have studied mechanical properties such as tensile strength and elongation at break, and also functional groups. The tensile strength of OPF 5% and 10% increased than polyvinyl alcohol matrix. Tensile strength OPEFB 10% slightly increase from polyvinyl alcohol. The elongation of composites both OPEFB and OPF decreased with increased of nanocellulose loading.

“…It is worth noting that the use of polymer nanocomposites in FDM to produce products with superior performance shows a brighter future than traditional polymer alloys or polymer composites. Up to now, nanofillers used in modified printed materials have mainly included cellulose nanocrystals (CNCs), nano‐silica, nanomontmorillonite, graphene and carbon nanotubes . However, it is difficult to achieve the desired results due to a single structure and function when they are used alone.…”

The preparation of 3D printed products with excellent comprehensive performance is still receiving much attention. Cellulose, the most abundant and green natural polymer, was used in this study to fabricate polymeric composites used for 3D printing. Specifically, novel cellulose nanocrystals/silica nanohybrids (CSNs) were synthesized via the sol-gel method using cellulose nanocrystals (CNCs) obtained by hydrolysis of sulfuric acid as raw materials, and the thermostability was significantly improved due to the adsorption of silica (SiO 2 ) on the surface of the CNCs via hydrogen bonding and covalent bonds. Subsequently, the CSNs were used in fused deposition modeling (FDM) with acrylonitrile-butadiene-styrene (ABS) as the matrix. Unlike ABS/CNC product which shows obvious yellowing, the ABS/CSN product shows a smooth undefiled surface, demonstrating their excellent applicability to high temperature FDM molding. Further, the effect of different silane coupling agents on the mechanical properties was compared and organically modified CSNs (oCSNs) were prepared using KH570 to optimize the dispersion of the filler and the interaction with the matrix. Satisfactorily, the addition of organically modified oCSNs not only does not degrade the fluidity but it also eliminates the warpage of FDM products and improves both layer adhesion and mechanical properties. This study provides a pioneering strategy for the thermal processing applications of CNCs and the modification of FDM products. RESULTS AND DISCUSSION Characterization of the CSNs Morphology and elemental analysis of the CSNsThe morphology and elemental analysis of the CNCs and the CSNs are shown in Fig. 2. Figure 2(a) demonstrates rod-like structures of the CNCs. Most of the CNCs possessed a length range of 100-500 nm and the diameters were a few nanometers, indicating that they had a large aspect ratio. Besides, the CNCs agglomerated together to form a bundle. CNCs are hydrophilic carbohydrate polymers with numerous hydroxyl groups and the strong Polym Int 2019; 68: 1351-1360

“…As such, PVA, as one of popular biopolymers has received great attention as the alternative to general synthetic polymers owing to its good flexibility, water solubility, recyclability and biotribological properties. PVA was widely used for industrial applications such as tissue engineering, pharmaceutical formation, drug delivery, cosmetics and biosensors Dorigato and Pegoretti, 2012;Huang and Wang, 2013;Cataldi et al, 2018). Carbon based nanofillers such as carbon nanotubes (CNTs) are considered as more effective nanoreinforcements.…”

Polyvinyl alcohol (PVA) nanocomposite films reinforced with bamboo charcoal (BC) nanoparticles were successfully fabricated via solution casting and their nanomechanical properties in terms of material phases were determined by a peak force quantitative nanomechanical tapping mode (PFQNM). Our experimental results revealed that the elastic modulus of PVA semicrystalline phase in stack-bundle form was 24 ± 4.2 GPa with the semicrystalline phase width being 20-76 nm, as opposed to 11.4 ± 3.1 GPa and 18-65 nm for corresponding PVA amorphous phase accordingly. The incorporation of BC nanoparticles enhanced the elastic moduli of both crystalline and amorphous phases of PVA by ∼51% and ∼100%, respectively. Moreover, the phase width was decreased to be in range of 5-53 nm for crystalline phase and 4-35 nm for amorphous phase.
