Abstract Polylactic acid (PLA) composites with multifunctional properties and minimal filler content are increasingly in demand across various industries. However, achieving a balance between high mechanical strength, electrical conductivity, thermal electromagnetic interference (EMI) shielding remains challenging. In this study, dual‐processing strategy combining Pickering emulsion templating melt blending is presented to hybridize 1D carbon nanotubes (CNTs) 2D graphene nanoplatelets (GNPs) within PLA matrix. This approach successfully forms stable dual‐filler network, ensuring uniform dispersion of the fillers. The results show that method significantly enhances performance resulting PM‐PG x C y (P: emulsion; M: blending; y: mass fractions GNPs CNTs, respectively). Specifically, 1.43 composite exhibits remarkable improvements strength (56.2 MPa), conductivity (43.5 S m −1 ), EMI effectiveness (20.1 dB), (0.34 W m·K outperforming prepared using either alone. These findings indicate effectively combines fillers, facilitating superior interfacial interactions enhancing PLA‐based composites. study offers new high‐performance low content, offering significant potential for applications electronics, packaging, technologies.

High-density polyethylene (HDPE) is a light and low-cost polymer widely explored as an excellent barrier material for γ-ray neutron radiation in situations of high exposure (e.g., aerospace). Nevertheless, this not suitable structural due to its low mechanical resistance. Herein, amino-functionalized carbon nanotubes (CNTs) graphene oxide (GO) were incorporated into HDPE statistically studied through Taguchi design experiments (DoE) model that investigated their synergistic effect. After incorporating these nanocarbons, microscopy images suggest homogeneous distribution HDPE. Furthermore, X-ray diffraction shows the crystallinity degree increased nucleation effect caused by nanofillers. Additionally, all nanocomposites presented improved microhardness resistance (up 69%), particularly when both nanocarbons matrix. The nanocomposite with higher had attenuation potential, exhibiting similar shielding HDPE, linear coefficient than Aluminum, reference material. Hence, study synergy between can be improve hardness without negatively affecting ability. Therefore, are potential materials applications requiring surface durability resistance, such air-/spacecraft systems.

Abstract This leading-edge overview delivers an all-inclusive knowledge on fundamentals, state-of-the-art, and technicalities of two important polymer categories filled with graphene quantum dots, namely conjugated polymer/graphene dots rubber/graphene nanocomposites. According to the literature up till now, facile efficient fabrication methods, like in situ polymerization, solution mixing, melt blending, etc. have been reported for these derived hybrids. The ensuing based nanocomposites were inspected microstructural, electrical conductivity, charge transportation, thermal/mechanical resistance, fluorescence properties, allied valuable physical features. Incidentally, we notice promising applications inimitable hybrids gas/molecular/piezoelectric sensors, supercapacitors, biomedical areas. Nevertheless, due limited reports applied sides conjugated/rubbery matrices, future research attempts seem indispensable resolve challenges optimized/controlled processing also unveil structure-property-performance links synergistic mechanisms developing next generation industrial level
