Natural lignocellulosic fibers (NLFs) have been used as a reinforcement for polymer matrix composites in the past couple of decades. Their biodegradability, renewability, and abundance make them appealing for sustainable materials. However, synthetic fibers surpass NLFs in mechanical and thermal properties. Combining these fibers as a hybrid reinforcement in polymeric materials shows promise for multifunctional materials and structures. Functionalizing these composites with graphene-based materials could lead to superior properties. This research optimized the tensile and impact resistance of a jute/aramid/HDPE hybrid nanocomposite by the addition of graphene nanoplatelets (GNP). The hybrid structure with 10 jute/10 aramid layers and 0.10 wt.% GNP exhibited a 2433% increase in mechanical toughness, a 591% increase in tensile strength, and a 462% reduction in ductility compared to neat jute/HDPE composites. A SEM analysis revealed the influence of GNP nano-functionalization on the failure mechanisms of these hybrid nanocomposites.

High-performance eco-friendly soft actuators showing large displacement, fast response, and long-term operational capability require further development for next-generation bioinspired soft robots. Herein, we report an electro-ionic soft actuator based on carboxylated cellulose nanocrystals (CCNC) and carboxylated cellulose nanofibers (CCNF), graphene nanoplatelets (GN), and ionic liquid (IL). The actuator exhibited exceptional actuation performances, achieving large displacements ranging from 1.

Copper, though highly conductive, requires improved wear resistance and thermal dissipation in applications that involve continuous movement and current-induced vibrations, such as power breakers. Conventional solutions, such as copper-tungsten alloys or lubricant use, face limitations in durability, friction, or environmental impact. This study explores the development of copper-graphene (Cu-GNPs) composite coatings using pulsed electrodeposition to enhance the tribological, thermal, and mechanical properties of circuit breaker components by adopting an industrially scalable technique.

High-performance and sustainable membranes for water desalination applications are crucial to address the growing global demand for clean water. Concurrently, electrospinning has emerged as a versatile manufacturing method for fabricating nanofibrous membranes for membrane distillation. However, widespread adoption of electrospinning for processing water-insoluble polymers, such as fluoropolymers, is hindered by the reliance on hazardous organic solvents during production.

Environmental issues have resulted in the forming of sustainable materials, including natural fiber-reinforced PLA composites; nonetheless, this composite has low water resistance, resulting in poor composite performance. This research aims to investigate the impact of adding a small amount of graphene nanoplatelets (GNP) on the water absorption (WA) characteristic of bamboo/kenaf-reinforced PLA hybrid composites. The physical behavior and water resistance of the composites, as well as the mechanical performance and surface after 14 days of immersion, were comprehensively investigated.

Article Synopsis
- A novel and cost-effective method for extracting cellulose nanofibers (ECNFs) from Imperata cylindrica grass was developed, resulting in high yield and purity.
- The extracted ECNFs exhibited impressive characteristics, including a uniform diameter, high crystallinity, and small crystal size, confirmed through advanced analytical techniques.
- ECNFs were shown to significantly improve the mechanical properties of chitosan composite films, while incorporating graphene nanoplatelets further enhanced their thermal stability, flame retardancy, and electromagnetic shielding capabilities.
