“…Graphite is also well known for its excellent thermal conductivity, and graphene-based dispersions and composites have been widely studied as media for heat dissipation and exchange. − ,, To determine whether the high surface area of GrNPs could be used to increase the rate of radiative heat transfer, dispersions of GrNPs were spray-coated onto the fins of aluminum heat sinks mounted on the backs of thermoelectric Peltier blocks (see the Experimental Section). The plates generated substantial amounts of heat when powered by a 12-V/5-Ah battery, with heat sink fins achieving a steady-state temperature of nearly 80 °C in ambient conditions (22.8 °C).…”

“…GrNPs are especially useful for supporting transduction mechanisms between charge and electron mobility, such as electrical double-layer (EDL) capacitors 31 and contacts for solid-state ion-selective electrodes (ISEs). 32 Graphitic materials are also well known for their excellent heat conduction properties, with GrNPs having been used as fillers in composites for heat exchangers 33 and heat sinks 34 and also as fluid suspensions for similar heat-transfer applications. 35 The spray-coating of GrNPs onto heat-exchange interfaces with large surface areas should thus be attractive from an additive manufacturing perspective, although such an application is yet to be reported.…”

Nonaqueous dispersions of graphene nanoplatelets (GrNPs) can be used to prepare thin films and coatings free of surfactants, but typically involve polar organic solvents with high boiling points and low exposure limits. Here, we describe the mechanochemical exfoliation and dispersion of GrNPs in volatile aprotic solvents such as ethyl acetate (EtOAc) and acetone, which rank favorably in green solvent selection guides. GrNPs in powder form were exfoliated with a solvent on a horizontal ball mill for 48 h and then sonicated at moderate power to produce suspensions in excess of 300 μg/mL with minimum loss of dispersion stability over 7 weeks at room temperature. Atomic force microscopy of individual particles indicates a median thickness and lateral width of 8–10 layers and 180 nm, respectively. GrNP films can be deposited by conventional airbrush equipment with a dry time of seconds and applied as layers and coatings that enhance the reproducibility and performance of electronic devices. We demonstrate the utility of spray-coated GrNPs as contact layers for low-cost electrochemical sensing with improvements in intrabatch reproducibility and as conformal coatings on metal heat sinks with enhanced rates of heat dissipation.

The mixing and processing of high-viscosity materials play a pivotal role in composite material processing. In this context, the internal meshing screw mixer, rooted in volume extensional rheology, offers distinct advantages, including heightened mixing efficiency, exceptional material adaptability, and favorable thermomechanical properties. This research endeavors to advance our understanding of these qualities by presenting an in-depth exploration of internal meshing screw mixing. To facilitate this, an internal meshing screw mixing experimental apparatus was meticulously constructed, accompanied by extensive numerical simulations and experimental investigations into its heat transfer characteristics. Two distinct heat transfer modes are established: Mode 1 entails the transfer of the high temperature from the outer wall of the stator to the interior, while Mode 2 involves the transmission of the high temperature from the inner wall of the rotor to the exterior. The ensuing research yields several notable findings: 1. It is evident that higher rotational speeds lead to enhanced heat transfer efficiency across the board. However, among the three rotational speeds examined, 60 rpm emerges as the optimal parameter for achieving the highest heat transfer efficiency. Furthermore, within this parameter, the heat transfer efficiency is superior in Mode 1 compared to Mode 2. 2. As eccentricity increases, a corresponding decline in comprehensive heat transfer efficiency is observed. Moreover, the impact of eccentricity on heat transfer efficiency becomes increasingly pronounced over time. 3. A lower gap dimension contributes to higher heat transfer within the system. Nevertheless, this heightened heat transfer comes at the expense of reduced stability in the heat transfer process. 4. It is demonstrated that heat transfer in Mode 1 primarily follows a convection heat transfer mechanism, while Mode 2 predominantly exhibits diffusion-based heat transfer. The heat transfer efficiency of Mode 1 significantly surpasses that of Mode 2. This research substantiates its findings with the potential to enhance the heat transfer efficiency of internal meshing screw mixers, thereby making a valuable contribution to the field of polymer engineering and science.
