Summary: In this study, PANF/rGO composite films were prepared by a simple yet efficient strategy using polymerization-induced aramid nanofiber (PANF) and reduced graphene oxide (rGO). The assembly of the two components was achieved through a low cost and scalable vacuum-assisted filtration method. The resulting PANF/rGO composite films showed excellent mechanical property, thermal stability, flame retardancy, electromagnetic interference shielding performance, and Joule heating performance, making them promising for practical engineering applications of aramid and graphene.

Summary: High-temperature defects induced by nitrogen doping accelerate grain growth and ordering of graphene films during graphitization, resulting in highly conductive films similar to highly oriented pyrolytic graphite. This not only paves the way for the technological application of highly conductive graphene films, but also provides a general strategy to improve the synthesis and properties of other carbon materials.

Summary: This paper proposes a new process for preparing printhead chips by bonding tantalum nitride thin-film heaters and SU-8 chamber film using UV curing optical adhesive. The new process simplifies the preparation process of chips and overcomes the limitations of traditional adhesive bonding methods. Experimental results show that the new process achieves a high bonding interface width and strength, and the printhead can stably eject binder droplets, opening up new possibilities for applications such as binder-jetting printing of powder.

Summary: This work developed a simple method to obtain regenerated cellulose nanoparticles (RCNPs) from delignified coffee parchment, and conducted a comprehensive physicochemical characterization of the obtained nanoparticles. The results showed that the RCNPs had high cellulose purity, high crystallinity of cellulose II, and spherical morphology. The RCNPs also exhibited good thermal stability and suspension stability, and when blended with PVA and Glycerol, showed potential for application in food packaging.

Summary: Polymer-based conductive and transparent thin films are essential in flexible organic electronic devices but susceptible to degradation and mechanical instability. The study demonstrates that depositing water or solvent drops on these films leads to buckling instability and formation of folds, which can be used to estimate material parameters and pattern surfaces at low cost for enhanced conductive pathways.

Summary: Cu-Ag core-shell nanowire (Cu@Ag NW) films were fabricated as transparent conductive films (TCFs) using vacuum filtration and transfer method (VFT) on glass substrates coated with polymer thin films. To enhance the adhesion between the NWs and substrates, the NWs were pressed against the substrates using capillary immersion force generated during ethanol dropping and evaporation. The resulting NW films showed good performances as TCFs, making them suitable for the fabrication of various optoelectronic devices by spin coating.
