“…At the same time some smaller RLFs are found to be incorporated in the rHDPE matrix. It's because the smaller particles have higher surface area 26 . The voids and the gaps between RLFs and rHDPE matrix observed reveal the low compatibility between the biofillers and the polymeric matrix.…”

Recycled plastic (rHDPE) was coupled with different weight percentage of ronier palm leaf fiber (RLFs) to prepare eco‐friendly polymer biocomposites. Fourier transform infrared analysis, tensile test, dynamic rheological test, hardness test, scanning electron microscopy (SEM) analysis, and density measurement were used to determine the structural, mechanical, morphological and physical properties of the biocomposites. The modulus showed excellent improvement with the addition of RLFs. G′ and G″ were found to increase with the increment of both the filler content and the angular frequency. At low frequencies, the loss factor was increased with the frequency and decreased with the RLFs content. However, at high frequencies, it was decreased with both the angular frequency and the RLFs content. The complex viscosity η* was found to be increasing and decreasing with the RLFs content and the angular frequency, respectively. SEM micrographs of tensile fractured surfaces of biocomposites show pulled out RLFs zones and voids due to the presence of agglomeration. Finally, the experimental Young's modulus data was compared with theoretical predictions. A good fit was obtained with Einstein Model.

“…However, nanocomposites need to be strong. Therefore, it is important to analyze the mechanical performance of polymer nanocomposites developed for EMI shielding [5,32,[54][55][56]. Figure 9a, b shows the representative stress-strain response of neat PPR and PPR/MWCNT nanocomposites samples from a three-point flexture test.…”

We report the electrical, mechanical and electromagnetic interference (EMI) shielding performance of polypropylene random copolymer (PPR)/multi-wall carbon nanotube (MWCNT) nanocomposites enabled via customized fused filament fabrication process. The electro-conductive PPR/MWCNT filament feedstocks were fabricated via shear-induced melt-blending process that allows 3D printing of nanoengineered composites even at higher MWCNT loading (up to 8 wt%). The uniform dispersion of MWCNTs in PPR matrix confirmed via Raman spectroscopy and scanning electron microscopy facilitates better mechanical, electrical and EMI shielding performance. The results furthermore show enhanced shielding properties and higher attenuation for the nanocomposites printed in 90° direction (~ − 37 dB for 8 wt% MWCNT loading). Effective interfacial adhesion between the beads with lesser extent of voids (confirmed via micro-computed tomography) endorsed low transmission loss in nanocomposites printed in 90° direction compared to samples printed in 0° direction. Surface architected structure (frustum shape) reveals higher specific shielding effectiveness (maximum ~ − 40 dBg−1cm3, + 38%) over the plain structure. The realization of excellent shielding effectiveness (~ 99.9% attenuation) of additive manufacturing-enabled PPR/MWCNT nanocomposites demonstrates their potential for lightweight and strong EMI shields.

“…Each monomer residue contains hydroxyl groups that form extensive intra-and inter-molecular hydrogen bonds with adjacent glucose residues in the same and nearby chains (Barhoum et al, 2020;Li et al, 2018;Moon et al, 2011;Shen et al, 2020). The mechanical stability of material plays an important role which could be explored in various applications (Verma et al, 2018). Cellulose-based biomaterials offer the advantage to fall under the category of mechanically stable and environmentally friendly.…”

Biopolymers have attracted considerable attention in various biomedical applications. Among them, cellulose as sustainable and renewable biomass has shown potential efficacy. With the advancement in nanotechnology, a wide range of nanostructured materials have surfaced with the potential to offer substantial biomedical applications. . The progress of cellulose at the nanoscale regime (nanocelluloses) with diverse forms like cellulose nanocrystals, nanofibres and bacterial nanocellulose) has imparted remarkable properties like high aspect-ratio and high mechanical strength, and biocompatibility. The amalgamation of nanocellulose together with magnetic nanoparticles (MNC) could be explored for a synergistic effect. In this review, a brief introduction of nano cellulose , magnetic nanoparticles and the synergistic effect of MNC is described. Further, the review sheds light on the recent studies based on MNCs with their potential in the biomedical area. Finally, the review is concluded by citing the remarkable value of MNC with their futuristic applications in other fields like friction layers for triboelectric nanogenerator (TENG), energy production, hydrogen splitting, and wearable electronics.
